Tropical monsoon type of climate.

Teacher's Note:

b) Mention both 'tropical' and 'monsoon' to ensure complete credit.

(b) Mention any two factors responsible for it. [2 Marks]

Answer:
1. The presence of the mighty Himalayan mountain range in the north which prevents freezing winds from Central Asia.
2. The reversal of wind systems (monsoon winds) due to differential heating and cooling of land and water.

b) State precise geographical controls governing Indian climatic conditions.

(ii) With the help of a suitable example explain how relief features affect the rainfall of a place. [2 Marks]

Answer:
Relief features act as barriers to moisture-laden winds. When moisture-laden winds strike mountain barriers, they are forced to rise, cool, and condense, causing heavy orographic rainfall on the windward side. For example, Mumbai (windward side of the Western Ghats) receives heavy rainfall, whereas Pune (on the leeward rain shadow side) receives scanty rainfall.

Teacher's Note:
a) Orographic rainfall is directly dependent on relief barriers.

Answer:
(a) Delhi experiences a continental type of climate as it is located in the interior, away from the moderating influence of the sea. Mumbai experiences an equable maritime climate due to its coastal location.
(b) Mango showers are pre-monsoon showers that occur along the coast of Kerala and Karnataka, helping in the early ripening of mangoes.

(c) North East monsoon winds blow from land to sea (offshore winds), and hence they are dry and contain very little moisture, resulting in little to no rainfall except over the Tamil Nadu coast.

Teacher's Note:
a) Contrast continentality with maritime moderation for temperature range questions.
b) Highlight the wind direction (offshore vs onshore) when explaining why winter monsoons are mostly dry.

(iv) Study the climatic data and answer the following questions:

(a) Calculate the annual range of temperature.
(b) What is the total rainfall during the monsoon season?
(c) On which coast is the station located? Give a reason for your answer. [3 Marks]

Answer:
(a) Annual range of temperature = Highest temperature - Lowest temperature = 30.4 degrees C (July) - 23.8 degrees C (January) = 6.6 degrees C.
(b) Total rainfall during the monsoon season (June to September) = 45.3 + 46.5 + 45.4 + 43.3 = 180.5 cms.
(c) The station is located on the eastern coast (Coromandel Coast / southeastern coast) of India because it receives significant rainfall during October and November (retreating monsoon / North East monsoon).

Teacher's Note:
a) Ensure correct identification of highest and lowest temperatures from the table for range calculation.
b) Winter/autumn rainfall maximum is the hallmark of stations situated along the Tamil Nadu (Coromandel) coast.

(c) Alluvial soil differs in texture. [3 Marks]

Answer:
(a) Black soil is formed in-situ by the weathering of underlying parent basaltic rock and has not been transported.
(b) Red soils are porous, deficient in nitrogen, humus, phosphorus, and lime, and formed over crystalline metamorphic rocks.
(c) Alluvial soil varies in texture from coarse sandy loam in upper river courses to fine clayey silt in river deltas due to sorting of sediments by running water.

(c) Tropical deciduous forests are commercially most exploited. [3 Marks]

Answer:
(a) Xerophytic plants have long roots to penetrate deep into the underground water table in arid regions to absorb moisture.
(b) Forest canopy intercepts rainfall, reduces surface runoff speed, and tree roots increase soil porosity, allowing rainwater to percolate into the ground.
(c) Tropical deciduous trees grow in pure stands rather than mixed forests, making lumbering easier and economically viable.
