Question 2. The region with high diurnal range of temperature
(a) Tropical rainforests
(b) Tropical grasslands
(c) Tropical desert regions
(d) Tropical Monsoon regions
Answer: (c) Tropical desert regions
In simple words: Tropical desert regions experience the largest differences between daytime high and nighttime low temperatures due to clear skies and lack of moisture.

🎯 Exam Tip: Remember that lack of humidity and cloud cover in deserts allows for rapid heating during the day and rapid cooling at night, leading to a high diurnal temperature range.

(a) Tundra Climatic Region
(b) Taiga Climatic Region
(c) West European Climatic Region
(d) China-type climatic region
Answer: (b) Taiga Climatic Region
In simple words: Lumbering is a key activity in the Taiga Climatic Region because it is characterized by extensive coniferous forests, which are valuable for timber.

🎯 Exam Tip: Associate specific climatic regions with their dominant vegetation types and corresponding economic activities like lumbering (coniferous forests in Taiga).

 

Question 4. The main reason behind the months of precipitation in the graphs of Monsoon climatic regions being different is
(a) ITCZ
(b) orographic rainfall
(c) hemispheres are different
(d) apparent movement of the sun
Answer: (a) ITCZ
In simple words: The shifting of the Intertropical Convergence Zone (ITCZ) is the primary factor influencing the timing of precipitation in monsoon climatic regions, leading to different rainy seasons across hemispheres.

🎯 Exam Tip: The ITCZ's migration significantly impacts global weather patterns, particularly the timing and intensity of monsoons. Understanding its role is crucial for questions on seasonal rainfall.

 

3. Give Geographical Reasons.

Question 1. In monsoon climate region, rainfall occurs in specific season.
Answer: In monsoon climate region, rainfall occurs in specific season because-
1. The differential heating and cooling of land and water creates low pressure on the land while the sea experiences high pressure.
2. This is strongly related to shifting of the ITCZ. During the summer the ITCZ moves north to the latitudes of 20°-25°.
3. Several months later, the moisture laden summer monsoon is replaced by dry north-east monsoon.
4. By this time, the ITCZ has shifted to the southern hemisphere.
5. In northern hemisphere, the winds move from sea to land bringing moisture along with them in summers and gives rainfall.
6. In southern hemisphere same conditions prevail when there are winters in the northern hemisphere.
In simple words: Monsoon rainfall is seasonal because it's driven by the differential heating of land and sea, causing pressure changes and the movement of the ITCZ, which brings moisture-laden winds during specific summer months.

🎯 Exam Tip: When explaining monsoons, always refer to the ITCZ's movement and the land-sea temperature contrast as key drivers for seasonal rainfall patterns.

 

Question 2. Taiga region is not found in Southern Hemisphere.
Answer: Taiga region is not found in Southern Hemisphere because-
1. There is not much land at higher altitude in the southern hemisphere (until inside the Antarctic circle) where it is permanently ice covered.
2. Most of the land is fairly close to oceans and thus tempered by marine warming.
3. Whereas, Taiga is found throughout the high Northern latitudes between Tundra and the temperate forest, characterised by coniferous forests.
4. The strong oceanic influence in the southern hemisphere reduces the severity of the winter, thus, affecting the temperature and precipitation.
In simple words: The Taiga region is absent in the Southern Hemisphere mainly due to the scarcity of landmass at suitable latitudes and the moderating effect of vast oceans, which prevent the extreme continental conditions necessary for Taiga forests.

🎯 Exam Tip: Relate the absence of specific biomes like Taiga in a hemisphere to the distribution of landmasses and oceanic influences, which modify climate significantly.

 

Question 3. The diurnal range of temperature is more in desert areas.
Answer: The diurnal range of temperature is more in desert areas because-
1. Deserts get hot during the day, but cool down rapidly during night. The main reasons for the temperature fluctuation between day and night are the lack of humidity and cloud cover.
2. Because of water's relatively high specific heat, humid air takes longer to warm or cool, while air on land warms or cools more quickly.
3. Because desert areas receive a large amount of sunlight, the temperatures can get very high, but during night the dry air cools quickly.
4. The lack of cloud cover overhead allows the warmer air to rise into the atmosphere while cooler air settles in its place.
5. Basically, desert temperature varies so much because there is less moisture and cloud to keep the heat there.
In simple words: Deserts have a high diurnal temperature range because the lack of moisture and clouds allows for rapid heating during the day due to intense sunlight and quick heat loss at night through radiation.

🎯 Exam Tip: Focus on the role of humidity and cloud cover in regulating temperature. Their absence in deserts directly leads to extreme daily temperature swings.

 

Question 4. There is no concept of season in equatorial regions.
Answer: There is no concept of season in equatorial regions because-
1. The equatorial region lies between 0° to 10° latitudes in both the hemispheres.
2. The sun is exactly overhead in the equatorial regions throughout the year giving maximum insolation.
3. Thus, constant high temperatures are experienced throughout the year, which gives rise to heavy convectional precipitation.
4. Days and nights are almost of equal length and thus, the concept of summer and winter as being hot and cold seasons do not exist in these parts.
In simple words: Equatorial regions lack distinct seasons because they receive consistent, intense sunlight throughout the year, leading to uniformly high temperatures and regular convectional rainfall.

🎯 Exam Tip: For equatorial climates, emphasize consistent insolation, high temperatures, and convectional rainfall as key reasons for the absence of seasonal variation.

 

Question 5. The Savannah region is prone to droughts.
Answer: The Savannah region is prone to droughts because-
1. The region lies between 10° to 20° N and S latitudes, where the sun's rays at noon are never far from overhead and thus the insolation is maximum and temperature is constantly high here.
2. Distinct wet and dry seasons of relatively equal duration are found. Most of the regions annual rainfall is experienced during the wet season and very little precipitation falls during the dry season.
3. A lengthy dry season and a relatively short wet season is the characteristic of Savannah region.
4. Thus, in Savannah region the dry season becomes more severe and often drought conditions prevail during the course of the year.
In simple words: Savannah regions are prone to droughts due to their distinct and often lengthy dry seasons, during which very little precipitation falls, despite high temperatures and maximum insolation.

🎯 Exam Tip: Highlight the pronounced wet and dry seasons characteristic of Savannah climate. The duration and intensity of the dry season are key to explaining drought susceptibility.

 

Question 6. Though Mussoorie and Dehradun are located on the same latitude, why is their climate different?
Answer: Though Mussoorie and Dehradun are located on the same latitude, their climate is different because-
1. Dehradun lies in the humid sub-tropical climatic region where the summers are long, hot and humid. Whereas, Mussoorie is a hill station in Dehradun district of Uttarakhand which lies in sub-tropical climatic regions that are very wet.
2. Dehradun lies at an elevation of average 450 m above mean sea level whereas Mussoorie is at an elevations of 1880 m above mean sea level.
3. In Dehradun during monsoon season there is often heavy and protracted rainfall, whereas in Mussoorie an average of 660 mm orographic rainfall is experienced.
4. The winter temperature is around 1°C and 20°C in Dehradun with fog commonly experienced. Mussoorie usually receives few spells of snowfall in December, January and February.
In simple words: Despite being on the same latitude, Mussoorie and Dehradun have different climates primarily due to their significant difference in altitude; Mussoorie, being a hill station at a much higher elevation, experiences cooler temperatures and snowfall compared to Dehradun's warmer, humid subtropical climate.

🎯 Exam Tip: When latitude is constant, factors like altitude, proximity to mountains (orographic rainfall), and local topography become critical in explaining climatic variations between two places.

In simple words: Monsoon regions have hot, humid summers with heavy rainfall and cooler, drier winters, primarily supporting agriculture, whereas Mediterranean regions experience hot, dry summers and mild, wet winters, ideal for winter-sown crops like olives and grapes.

🎯 Exam Tip: The key differentiator is the timing of rainfall: monsoons receive summer rain, while Mediterranean climates receive winter rain due to shifting pressure belts.

 

5. Answer In Detail.

Question 1. Explain, with examples, the effects of latitude on a place's climate.
Answer: Latitudes affect the climate of a place in different ways-
Places close to the equator receive more sunlight:
1. The equatorial region lying between 0° to 5° North and South latitudes receive maximum heat as the sunrays are directly falling on the equator.
2. Due to which the region receives heavy rainfall throughout the year.
3. As a result, evergreen forests are found is such regions.
4. Example: Amazon basin.
Places close to the tropical region receives less sunlight:
1. Temperature gradually decreases with increasing distance from the equator, as the angle of sun's rays decreases from it.
2. In tropical areas the sun rays become slanting and thus it gives less heat but covers more area.
3. Example regions lying between Tropic of Cancer 231/2°N to Tropic of Capricorn 23/4°S. Similarly, in the temperate regions 66X/20N and S and the polar regions the climate become extremely cool as the intensity of heat decreases. These regions are thus covered by snow.
In simple words: Latitude primarily determines climate by influencing the angle of the sun's rays; equatorial regions receive direct, intense sunlight causing high temperatures and rainfall, while higher latitudes receive slanting rays, resulting in cooler temperatures and snow cover.

🎯 Exam Tip: When discussing the effect of latitude, always link the angle of the sun's rays to the intensity of insolation received, which then dictates temperature and precipitation patterns.

 

Question 2. Explain with examples, how winds affect the climate of a place.
Answer:
1. The winds affect the climate because they create the hot and cold air which moves around.
2. Prevailing winds affect the climate of an area. The direction of local winds is determined by the daily temperature of variations.
3. When winds blow from warm areas, they carry higher temperatures while winds blowing from cold areas carry lower temperatures.
4. Thus, winds bring in heat/ cold from the direction it has been blown from and thus changes the temperature of the place which affects the climate. For e.g., cold wind waves from the Himalayas carry coldness to the parts of the Deccan plateau.
5. Winds that blow from the sea often carry moisture and give rain to the coast. For e.g.. south-west monsoon winds give heavy rainfall in the western coastline of India.
6. Some winds are warm and dry, they increase the temperature during winter season. For example, winds that blow to Britain from warm areas such as Africa are warm and dry. Such warm and dry winds increase the summer temperature in some areas.
In simple words: Winds influence climate by transporting air masses with specific temperature and moisture characteristics from their source regions; for example, cold winds from mountains bring coolness, while moist winds from oceans bring rainfall.

🎯 Exam Tip: Focus on two main effects of winds on climate: temperature moderation (carrying heat or cold) and precipitation (carrying moisture from oceans or land).

 

Question 3. Russia is larger than Chile in area but does not experience climatic diversity as Chile. Explain.
Answer:
1. The latitude and longitude of Russia is 61.5240°N and 105.3188°E respectively. It is located in northern Asia, between Europe on one side and North Pacific Ocean on the other side.
2. Chile is situated along western margin of South American continent. Its latitude and longitude are 35.6751°S and 71.5430°W respectively.
3. Russia has continental location since it is surrounded to south and west by huge landmass, and to the north lies Arctic ocean which is frozen, so it is like snow covered land.
4. Thus, due to continental location there are dry summer and very cold winters with temperatures of -30° and less and sometimes heavy snowfall.
5. The winter is mostly dry, snow covers the ground from the end of October to mid-March.
6. In Chile the coastal location and the east-west extent is very less.
7. There is a lot of climatic diversity in Chile. There is Atacama Desert in the north, Mediterranean climate at the central part, extreme cold climate in the east.
8. The most important factors that control the climate of Chile are Pacific anticyclone, cold Humboldt ocean current and mountain ranges along the coastline.
9. Thus, though Russia is larger than Chile in area but does not experience climatic diversity as Chile.
In simple words: Chile, despite being smaller, exhibits greater climatic diversity than Russia due to its unique north-south elongated shape and coastal mountain ranges, which lead to a variety of climates from deserts to Mediterranean and extreme cold, unlike Russia's largely continental and uniformly cold climate.

🎯 Exam Tip: Geographical extent, orientation (north-south vs. east-west), continental vs. coastal location, and the presence of significant topographical features like mountain ranges are crucial for explaining climatic diversity.

 

Question 4. Explain the factors affecting climate of a place giving examples.
Answer: Factors affecting climate of a place are as follows
ℹ️ चित्र व्याख्या (Diagram Explanation): यह आरेख एक फ्लोचार्ट के रूप में किसी स्थान की जलवायु को प्रभावित करने वाले छह प्रमुख कारकों को दर्शाता है। ये कारक हैं अक्षांश (Latitude), ऊँचाई (Altitude), समुद्र से दूरी (Distance from the Sea), प्रचलित पवनें (Prevailing Winds), समुद्री धाराएँ (Ocean Currents), और ढलान का पहलू (Aspect of Slope)। यह छात्रों को जलवायु निर्धारकों की एक स्पष्ट और संक्षिप्त सूची प्रदान करता है।
Latitude: Latitude is the primary factor influencing distribution of atmospheric temperature. Generally, latitudes of high degrees are less warm than the low degrees of latitudes. Thus, sun's rays making a high angle to the ground, experience high temperature throughout the year. Temperature gradually decreases with increasing distance from the equator as the angle of the sun's rays decreases away from it. Hence, the polar region experiences very low temperature.
Altitude: The atmosphere is indirectly heated by terrestrial radiation from surface of the earth. Therefore, the place near the sea level experiences higher temperature than the places situated at higher altitude. In other words, the temperature generally decreases with increase in height. The rate of decrease of temperature with increase in height is known as Normal Lapse rate. It is 6.4°C per 1000 meters altitude.
Distance from the Sea : The location of place with respect to the sea also determines the temperature of that place. Though, the sun provides same amount of heat over land and water bodies, there is difference in their heating and cooling capacity. Compared to land, the sea (water) gets heated slowly and loses heat slowly. On the other hand, land heats up and cools down faster. Therefore, the variation in temperature over the water bodies is less as compared to land masses. The coastal areas come under the moderating influence of the sea and land breezes and experience moderate or equable climate while interior parts of the continents experience extreme climate.
Prevailing winds : Winds affect the temperature and rainfall of any area. Winds carry with them the temperature of their source regions. Hot winds increase the temperature while cold winds decrease the temperature, e.g., cold wind waves from Himalayas carry low temperature to parts of the Deccan Plateau. Thus, south west monsoon winds in India reduce the temperature after the onset of monsoon in June all over the country.
Some winds carry moisture and give rain to the area they visit. For example, South-west monsoon winds give rainfall to western coastline of India.
Ocean currents : Ocean currents considerably influence temperature of the adjacent land area. Warm currents raise the temperature of the coastal areas, whereas cold currents reduce the temperature near the coast where they flow.
Aspect of slope : In the northern hemisphere the south facing slopes and in the southern hemisphere the north facing slopes always face the sun. Hence, sun facing slopes are warmer and the opposite slopes are cooler.
In simple words: Climate is influenced by latitude (sun's angle), altitude (temperature decrease with height), distance from the sea (moderating effect), prevailing winds (carrying temperature and moisture), ocean currents (warming or cooling coasts), and aspect of slope (sun exposure).

🎯 Exam Tip: When listing factors affecting climate, provide a concise explanation and a relevant example for each to demonstrate a comprehensive understanding.

11th Geography Digest Chapter 4 Climatic Regions Intext Questions And Answers

Use Your Brain Power!

Question 1.
(i) Have you ever thought why there is difference in the skin colour of various people in the world?
(ii) Why all the people in the world do not eat same food?
(iii) Why there is a variety in clothing pattern and types too? Even our houses are different.
(iv) How come flora and fauna are restricted to a particular region?
(v) Why different fruits are found in different places? (Textbook Page No. 44)
Answer:
(i) There is variation in skin colour of people depending on the latitudes. For. e.g., people near the equator are dark since the sunrays are vertical and hence there is too much heat, while people in temperate or polar region are fair since sunrays in these regions are slanting due to increase in distance from sun. Hence, there is low temperature and colour of skin is fair.
(ii) There is variation in food because food depends on geographical factors like climate, soil, location etc. For example, in extreme cold climate areas soil is covered with snow, so agriculture is not possible, people eat fish and meat of fur bearing animals. The countries located along the coastline eat fish and rice because fishing is carried out at the coastal areas and rice is grown on fertile delta of the river along the coastline.
(iii) People prefer to use clothes according to climate. For example, Inuits in Polar region wear fur clothes due to extreme cold climate, Europeans wear woollen cloths in winter due to cold climate, Asians mostly wear cotton clothes except in winter.
The pattern of house depends upon the climate and availability of material in the surrounding area. For example, in heavy rainfall areas houses have sloping roofs, in hot climatic areas houses are made up of stones or thick walls to prevent the effect of outside hot air.
People use material available in the surrounding area for construction of houses. For example, Inuits in Polar region use snow to build houses, since it is available in plenty. These peculiar houses are called Igloos.
(iv) Particular temperature and rainfall are essential for the growth of flora. For example, coniferous forest grows in cool climate and snowfall. Flora provides food and shelter to fauna, therefore wherever there is thick flora, fauna is bound to be there. In grassland region grass eating animals like dear, antelope, rabbits are seen but the camel is seen only in the desert.
(v) Every fruit crop requires particular type of climate; therefore, different fruits grow in different areas depending upon the climate. For example, apples are grown in Jammu and Kashmir, mangoes, cashew nuts and jackfruits are grown in the Konkan region due to suitable climate.
In simple words: Human characteristics (skin color, food, clothing, housing) and natural distribution of flora and fauna and fruits are all largely determined by the local climate, which dictates environmental conditions, resource availability, and adaptive responses.

🎯 Exam Tip: When explaining human and natural variations globally, always connect them to the underlying climatic conditions, emphasizing adaptation and resource dependency.

In simple words: Human activities like diet, clothing, housing, and agriculture are directly shaped by local climate, geography, and resource availability across different regions of the world.

🎯 Exam Tip: Understanding how geographical factors dictate human lifestyles is key for comprehensive answers in human-environment interaction questions.

Question 2.
(i) What would be the annual range of temperature in this region?
(ii) Where is this type of climate found in India?
Answer:
(i) In equatorial region both diurnal and annual range of temperature will be low as it experiences high temperature all year round. The annual range of temperature may be as low as 3°C.
(ii) This type of tropical rainforest climate is found in north eastern states of India, western coast of West Bengal, and Andaman and Nicobar Islands.
In simple words: Equatorial regions experience consistently high temperatures year-round with a very small annual temperature range, typically seen in India's northeastern states and islands.

🎯 Exam Tip: Remember that equatorial regions are characterized by low annual temperature range and high rainfall, crucial points for describing their climate.

Question 3.Comment upon the type of weathering which will occur in this region.
Answer: Mechanical and chemical weathering is predominant in this region.
In simple words: Both physical and chemical processes are highly active in breaking down rocks and soil in this region.

🎯 Exam Tip: Predominance of both weathering types indicates a dynamic environment, often linked to areas with significant temperature fluctuations and moisture.

Question 4.
(i) Which agricultural crops are produced here?
(ii) Why are longitudes not given in geographical distribution?
Answer:
(i) Maize and rice are grown all over Savannah region. Sorghum and millets are grown in northern Savannah. Stray crops and vegetables are grown in all regions.
(ii) Temperature is the main element of climate. The temperature varies with latitude and not with longitudes. Geographical distribution is the natural arrangement of the various forms of plants and animals in different regions and localities of the earth. This distribution varies with the latitude as we go away from the equator towards the poles. Thus, longitudes are not given.
In simple words: Savannah regions produce crops like maize, rice, sorghum, and millets; geographical distributions of climate are primarily mapped by latitude because temperature, a key climate factor, varies significantly with distance from the equator, not longitude.

🎯 Exam Tip: For geographical distributions, focus on latitude's impact on temperature and climate zones, as longitude primarily affects time and not climate patterns.

Question 5.Comment upon the rate of weathering in this climate.
Answer: Mechanical or physical weathering is predominant in arid regions. The rate of weathering is very slow in this region.
In simple words: In arid climates, mechanical weathering is the main process, but its overall rate is very slow due to limited moisture for chemical reactions.

🎯 Exam Tip: Low moisture in arid regions leads to slow weathering, predominantly mechanical due to temperature changes, not chemical breakdown.

Question 1. Note the values of the axes, how different are these graphs from the earlies ones?
Answer: The values of Taiga or Sub-Arctic regions show the mean annual temperature below freezing point (0°C) that is from 0° to -35° C. These values are not observed in rest of the graphs.
In simple words: These graphs are unique because their temperature scales go well below freezing (0°C to -35°C), which wasn't seen in the previous climate graphs.

🎯 Exam Tip: Pay attention to the range of values on the axes, especially for temperature, as it highlights key climatic differences between regions.

Question 2. Note the highest and the lowest temperature and their months.
Answer: In Whitehorse, the highest temperature recorded is around 20.0°C in the month of July, whereas January is the coldest month with average temperature of -23°C. In Arkhangelsk, the highest temperature is in the month of July around 20°C and lowest in the month of January around -18°C.
In simple words: Both Whitehorse and Arkhangelsk experience their warmest temperatures (around 20°C) in July and their coldest temperatures (around -18°C to -23°C) in January.

🎯 Exam Tip: Clearly state both the highest and lowest temperatures along with their corresponding months for each location to score full marks.

Question 3. Note the highest and lowest rainfall and their months.
Answer: Highest rainfall recorded is about 35 to 37 mm in the months of July, August in Whitehorse and lowest is in the month of April with just 9 mm. In Arkhangelsk, the greatest amount of precipitation occurs in August with an average of 66 mm. The lowest amount of rainfall occurs in February. The average is this month in 27 mm.
In simple words: Whitehorse gets most rain in July-August and least in April, while Arkhangelsk has its highest rainfall in August and lowest in February.

🎯 Exam Tip: Differentiate between rainfall amounts and months for each location mentioned, ensuring precise data points are included.

Question 4. Why does not a place from Southern Hemisphere appear here?
Answer: There isn't much land at higher latitudes in hemisphere (until inside the Antarctic circle where it is permanently ice covered) and most of that land is fairly close to oceans and it has effect of marine warming.
In simple words: The Southern Hemisphere lacks large landmasses at high latitudes (beyond the Antarctic circle), and the land present is warmed by the ocean, preventing the distinct sub-arctic continental climates shown here.

🎯 Exam Tip: Focus on the geographical distribution of landmasses and oceanic influence as key reasons for the absence of such climatic regions in the Southern Hemisphere.

Question 5. What factors are responsible for this climate?
Answer: Located in large Continental landmass between 55°-65° latitude, the Sub-Arctic climate is removed from any moderating influence of an ocean. It therefore, experiences a very large range in annual temperature. During the summer it is dominated by the westerlies and cyclonic activity the winter it is the polar hight and Easterlies. The Sub-Arctic climate has continental polar air masses.
In simple words: This climate is caused by large continental landmasses far from oceans at 55°-65° latitude, leading to extreme temperature variations, with westerlies and cyclones in summer, and polar highs and easterlies with continental polar air masses in winter.

🎯 Exam Tip: Identify and explain the interplay of continental location, latitude, distance from the ocean, prevailing winds, and air masses as primary factors.

Question 1. Why is it that both the graphs are from the northern Hemisphere?
Answer: Tundra is located at the top of the world, near the north pole. Tundra is a Finnish word which means barren land. Thus, Tundra region having least vegetation and polar or arctic climate is found in North America and Eurasia between the southern limit of the permanent ice caps in the north and the northern limit of temperate coniferous forest of taiga climate in the south.
In simple words: Tundra climates are mostly found in the Northern Hemisphere because the vast landmasses at very high latitudes (near the North Pole) allow for the formation of these barren, permanently frozen regions between the ice caps and taiga forests.

🎯 Exam Tip: Connect the concept of tundra (barren land) with its high-latitude location in the Northern Hemisphere and its position relative to ice caps and taiga forests.

Question 2. Which are the warmest and the coolest months?
Answer: In Barrow, the warmest month is July while lowest temperature is in the month of February. Same temperature conditions are observed in Barentsburg.
In simple words: In both Barrow and Barentsburg, July is the warmest month, and February is the coolest.

🎯 Exam Tip: For comparative questions, clearly state the warmest and coolest months for all locations or note if they share the same pattern.

Question 3. What is the annual range of temperature?
Answer: The average annual range of temperature in Barrow is -12.2°C while in Barentsburg it is -5.9° C.
In simple words: The average yearly temperature swing in Barrow is -12.2°C, and in Barentsburg, it's -5.9°C.

🎯 Exam Tip: Calculate the annual range by finding the difference between the highest and lowest monthly average temperatures.

Question 4. Why does not the duration of day (sometimes more than 24 hours) influence its temperatures or precipitation?
Answer: This is because the sun's rays are oblique and little insolation is received being at higher latitude -65° to 90° North.
In simple words: Even with very long daylight hours at high latitudes, the sun's rays are so slanted that they provide very little direct heat (insolation), which means temperatures remain low and don't significantly increase precipitation.

🎯 Exam Tip: Emphasize the angle of the sun's rays (obliqueness) and the resulting low insolation at high latitudes as the primary reason for consistently low temperatures, despite extended daylight.

🎯 Exam Tip: Clearly identify the months of peak and minimal precipitation for each location, indicating the total amount if available from the graph for precision.

Question 3. In what way do you find similarities of this climate with other climate types of high latitudes?
Answer: Precipitation is very low in high latitude regions and mostly it is in the form of snowfall. Temperature is below freezing point (CPC) in all the high latitude regions. This is because the sun's rays are oblique and hence temperature is low. These regions are mostly under permanent snow cover.
In simple words: High-latitude climates, including these, share characteristics like very low precipitation (often snow), temperatures consistently below freezing, slanted sun rays causing low heat, and permanent snow cover.

🎯 Exam Tip: Compare and contrast highland climates with high-latitude climates, highlighting similarities in precipitation type (snowfall), snow cover, low temperatures due to insolation, and the effect of altitude.

Question 4. What factors influence this type of climate?
Answer: Little or no insolation during most of the months in a year, oblique sunrays are the factors responsible for this type of climate.
In simple words: This climate is primarily influenced by the extremely low amount of sunlight received throughout the year due to the very slanted angle of the sun's rays at these high latitudes.

🎯 Exam Tip: The primary factors are low insolation (incoming solar radiation) and the highly oblique angle of the sun's rays, directly linked to high latitude.

Question 1. Which are the warmest and the coolest months?
Answer: The warmest month is June while coolest month is January in Shimla. November is the hottest month and July is the coolest month in El Alto.
In simple words: In Shimla, June is warmest and January is coolest. In El Alto, November is hottest and July is coolest.

🎯 Exam Tip: Clearly state the warmest and coolest months for each location, noting any differences due to their respective hemispheres (Shimla in Northern, El Alto in Southern).

Question 2. Name the months of highest and lowest precipitation.
Answer: Most of the precipitation is in the months of July, whereas driest month is November is in Shimla. Precipitation is highest in January and lowest in June in El Alto.
In simple words: Shimla gets most precipitation in July and is driest in November. El Alto has highest precipitation in January and lowest in June.

🎯 Exam Tip: Identify the months of highest and lowest precipitation for both Shimla and El Alto, specifying their respective seasonal patterns.

Question 3. In what ways do you find similarities of this climate with other types of high latitudes?
Answer: In these regions, precipitation is in the form of snowfall. The regions are covered by snow. Temperature is very low, as the sunrays are oblique and little insolation is received. Temperature decreases with increasing altitude.
In simple words: Highland climates share similarities with high-latitude climates: precipitation often as snowfall, snow-covered regions, very low temperatures due to oblique sunrays and low insolation, and decreasing temperature with increasing altitude.

🎯 Exam Tip: Compare and contrast highland climates with high-latitude climates, highlighting similarities in precipitation type (snowfall), snow cover, low temperatures due to insolation, and the effect of altitude.

Question 4. Why are the axis showing temperature different in both the graphs?
Answer: Shimla is located at 31°6 N to 77°10 E and its elevation is 2,276 m whereas El Alto is located on 16°31 S to 68°10 W with an elevation of 4,150 mts. The temperature axes are different because temperature decreases with increasing altitude, and these places have significantly different elevations and latitudinal positions, resulting in distinct temperature ranges.
In simple words: The temperature axes differ because Shimla (2,276m, Northern Hemisphere) and El Alto (4,150m, Southern Hemisphere) have vastly different altitudes and locations, which lead to different temperature ranges according to the principle that temperature drops with higher elevation.

🎯 Exam Tip: When explaining differences in graph axes, always link them back to the specific geographical data (latitude, longitude, and especially altitude for highland climates) of the locations.

Question 5. What factors influence this type of climate?
Answer: The higher reaches of mountain, altitude, location of leeward or windward side, precipitation are the factors affecting climates of mountain type of climate.
In simple words: Mountain climates are influenced by high altitude, the specific side of the mountain (leeward or windward) which affects moisture, and overall precipitation patterns in the higher mountain regions.

🎯 Exam Tip: List the key geographical factors – altitude, mountain orientation (windward/leeward), and precipitation – as the primary drivers of mountain climate.
