Explanation: The Bay of Bengal branch moves northwards along the east coast initially affecting northeastern India and the eastern coastal plains with heavy rainfall.
Explanation: The Bay of Bengal branch moves northwards along the east coast initially affecting northeastern India and the eastern coastal plains with heavy rainfall.
Q15. The Inter-Tropical Convergence Zone (ITCZ) is important because:
Answer: C.
Explanation: ITCZ is the convergence zone near the equator where trade winds meet, leading to rising air and frequent rainfall; its seasonal shift influences monsoon patterns.
Explanation: ITCZ is the convergence zone near the equator where trade winds meet, leading to rising air and frequent rainfall; its seasonal shift influences monsoon patterns.
Q16. Why does a low-pressure area develop over northwest India in summer?
Answer: B.
Explanation: Intense solar heating during pre-monsoon months raises surface temperatures causing air to rise and a low-pressure region to form over the heated land, drawing moist winds from the sea.
Explanation: Intense solar heating during pre-monsoon months raises surface temperatures causing air to rise and a low-pressure region to form over the heated land, drawing moist winds from the sea.
Q17. Cyclones forming in the Bay of Bengal commonly affect which season(s)?
Answer: B.
Explanation: Cyclonic depressions often form during the monsoon and post-monsoon seasons, bringing intense localized rainfall especially to eastern and southern coasts.
Explanation: Cyclonic depressions often form during the monsoon and post-monsoon seasons, bringing intense localized rainfall especially to eastern and southern coasts.
Q18. 'Nor'westers' are most associated with which of the following?
Answer: B.
Explanation: Nor'westers are violent thunderstorms occurring in eastern India (e.g., West Bengal, Odisha) during the pre-monsoon hot season, bringing sudden heavy rain.
Explanation: Nor'westers are violent thunderstorms occurring in eastern India (e.g., West Bengal, Odisha) during the pre-monsoon hot season, bringing sudden heavy rain.
Q19. Which of the following reduces the moisture content of winds as they move inland over mountains?
Answer: B.
Explanation: As moist air ascends windward slopes it cools and precipitates, thus losing moisture before descending on the leeward side leading to drier conditions.
Explanation: As moist air ascends windward slopes it cools and precipitates, thus losing moisture before descending on the leeward side leading to drier conditions.
Q20. The withdrawal of monsoon from India typically begins in:

Q25. The Thar Desert receives low rainfall mainly because:
Answer: B.
