C. Answer The Following:

 

ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र पृथ्वी के विभिन्न अक्षांशीय ताप कटिबंधों को दर्शाता है। इसमें 0° भूमध्य रेखा से लेकर 90° उत्तरी और दक्षिणी ध्रुव तक फ्रिजिड (शीत), समशीतोष्ण (टेम्परेट) और टॉरिड (उष्ण) कटिबंध दिखाए गए हैं, जो सूर्य के प्रकाश के आपतन कोण के आधार पर तापमान के वितरण को समझाते हैं।

 

Question 1. Explain with a diagram, the effect of the spherical shape of the earth on the temperature at different latitudes.
Answer:
• Due to the spherical shape of the earth and the resultant curvature of the surface, sunrays occupy a larger or a lesser area.
• Equatorial regions which receive straight rays of the sun occupy less space and heat received is more.
• Polar regions receive slant rays of the sun occupy larger space but the heat received is less.
In simple words: The Earth's round shape causes sunrays to hit different latitudes at varying angles, leading to an unequal distribution of heat. Direct rays at the equator concentrate heat, while slanted rays at the poles spread out, resulting in less warmth.

🎯 Exam Tip: When explaining geographical phenomena, always link cause and effect. The spherical shape of Earth is the cause, and unequal temperature distribution is the effect, which is fundamental to understanding climate zones.

 

Question 2. What is the relation between the latitudinal extent and temperature of a region?
Answer:
• 0° and 23° 30′ North and South perpendicular rays. Temperatures are higher throughout the year.
• 23° 30′ and 66° 30′ North and South receive extreme slant rays. Temperatures are moderate.
• 66° 30′ and 90° North and South receive extreme slant rays. Temperatures are very low.
In simple words: Temperature is directly related to latitude: closer to the equator (0° to 23°30' N/S), temperatures are high due to direct sunrays; in the mid-latitudes (23°30' to 66°30' N/S), temperatures are moderate due to slanted rays; and near the poles (66°30' to 90° N/S), temperatures are very low because of extremely slanted rays.

🎯 Exam Tip: Memorize the major latitudinal zones (Torrid, Temperate, Frigid) and the general temperature characteristics associated with each. This helps in quickly analyzing climate patterns.

 

Question 3. What makes the isotherms run zigzag over continental areas?
Answer: Isotherms run zigzag over continental areas because the temperature is influenced by its physical set up and height above the mean sea level on the continent.
In simple words: Over continents, isotherms appear zigzag because landforms, altitude, and varying absorption/radiation properties of land create diverse temperature patterns, unlike the more uniform temperatures over oceans.

🎯 Exam Tip: Understand the concept of continentality. Land heats and cools faster than water, and variations in topography (mountains, plains) also significantly influence local temperatures, causing isotherms to deviate from straight lines.

Give Geographical Reasons For The Following Statements:

 

Question 1. There is unequal distribution of heat received from the Sun.
Answer: The unequal distribution of heat received from the Sun is because:
• The earth is spherical in shape.
• The rays which fall on the equator are straight, occupy less area and give more heat.
• The rays which fall on the curvature i.e., on the polar regions are slant rays which occupy large area and give less heat.
In simple words: The Earth's spherical shape causes sunrays to strike at different angles across latitudes; perpendicular rays at the equator concentrate heat, while slanted rays at the poles spread out, leading to an uneven distribution of solar energy globally.

🎯 Exam Tip: This is a core concept. Always link the Earth's spherical shape to the varying angle of insolation, which directly explains the unequal distribution of solar energy and the formation of temperature zones.

Answer The Following Questions In Short:

 

Question 1. Explain the movement of ocean currents from equator to the polar region.
Answer: Due to temperature differences, both upward and horizontal currents develop in the ocean. Besides temperature differences, factors like winds and differences in the density of water also give rise to horizontal currents. These ocean currents flow from the equator to the polar region and from the polar region to the equator.
In simple words: Ocean currents move due to temperature, wind, and water density differences, flowing both from the equator to the poles and vice-versa.

🎯 Exam Tip: Focus on the main causes (temperature, wind, density) and the general direction of ocean currents for full marks.

 

Question 2. Explain the effect of the ocean current flows from the frigid to the torrid zone.
Answer: When an ocean current flows from the frigid to the torrid zone, it reduces the temperature of the coasts in the torrid zone. When a current flows from the torrid to the frigid zone, it increases the temperature of the coasts in the frigid zone.
In simple words: Cold currents from frigid zones cool torrid zone coasts, while warm currents from torrid zones warm frigid zone coasts.

🎯 Exam Tip: Remember the reciprocal effect: cold currents reduce temperature, warm currents increase it, depending on the zone they flow into.

 

I Can Do This!

Answer: Factors influencing temperature are latitude, winds, nearness to the sea, continentality, vegetation cover, cloud cover, physical set up, height above sea level and industrialisation.
In simple words: Temperature is affected by many factors like location (latitude), wind, proximity to oceans, landmass size, plant life, clouds, altitude, and human activities.

🎯 Exam Tip: Provide a comprehensive list of factors to demonstrate a full understanding.

 

Question 3. Describe the global distribution of temperature with its characteristics.
Answer: The isotherms in the southern hemisphere are fairly parallel to the latitudinal lines. From South Pole to the Tropic of Capricorn the distance between these lines is almost equal. As the proportion of land in the southern hemisphere is limited, temperatures in these parts are largely influenced by latitude.
In the northern hemisphere, the distance between these lines varies. In this hemisphere, the proportion of land is comparatively greater. This affects the distribution of temperature. These effects are seen in the form of variations in the distance between the isotherms and curved nature of these lines.
In simple words: Global temperature distribution shows parallel isotherms in the southern hemisphere due to less land, making latitude the main factor. In the northern hemisphere, more land causes isotherms to vary and curve, reflecting a more complex temperature pattern.

🎯 Exam Tip: Clearly differentiate the characteristics of temperature distribution in the Northern and Southern Hemispheres, specifically mentioning the role of landmass. Isotherms are key here.

 

Question 4. Describe the structure of a thermometer.
Answer: A vacuum glass tube is filled with mercury or alcohol is mounted on a wooden board. There are two temperature scales showing Celsius and Fahrenheit.
In simple words: A thermometer consists of a vacuum glass tube containing mercury or alcohol, fixed on a board, with scales for measuring temperature in Celsius and Fahrenheit.

🎯 Exam Tip: Mention the key components (vacuum glass tube, mercury/alcohol, mount) and the common units of measurement (Celsius, Fahrenheit).
