Consider the following statementsThe South-West monsoon originates in ...
The southwest monsoon brings rains towards the end of summer as the high pressure built in the India Ocean pushes the wind masses towards the low pressure formed on land. The southwestern summer monsoon occurs from July through September. Northern and central Indian subcontinent heats up during the hot summers. This causes a low pressure area over the northern and central Indian subcontinent. To fill this void, the moisture-laden winds from the Indian Ocean rush in to the subcontinent. These winds, rich in moisture, are drawn towards the Himalayas. The Himalayas act like a high wall, blocking the winds from passing into Central Asia and forcing then to rise. As the clouds rise their temperature drops and precipitation occurs. 4. Second Civil Disobedience Movement- 1932

Consider the following statementsThe South-West monsoon originates in ...
The correct answer is option 'A', which means statements 1 and 4 are correct. Let's understand each statement in detail:
1. Low pressure in the Punjab plain:
The South-West monsoon in India is driven by the presence of low-pressure systems in the region. During summer, the intense heating of the landmass in the Indian subcontinent creates a low-pressure area over the Punjab plain. This low-pressure region acts as a trigger for the monsoon winds to move towards India from the southwest.
2. High pressure in areas South of India:
This statement is incorrect. The South-West monsoon is not caused by high pressure in areas south of India. Rather, it is the low pressure over the Indian subcontinent that draws in the monsoon winds.
3. Equatorial low being filled up by descending air current:
This statement is incorrect. The Equatorial low, also known as the Intertropical Convergence Zone (ITCZ), is a belt of low pressure near the equator. It is formed due to the convergence of trade winds from both hemispheres. The South-West monsoon winds do not originate from the equatorial low but are influenced by other factors, such as the low pressure over the Indian subcontinent and the presence of the Himalayas.
4. The Himalayas:
This statement is correct. The presence of the Himalayas plays a crucial role in the formation and direction of the South-West monsoon winds. As the monsoon winds approach the Indian subcontinent, they encounter the barrier of the Himalayan mountain range. The Himalayas act as a barrier and force the monsoon winds to rise, leading to orographic rainfall on the windward side. This rainfall is one of the primary sources of water for agriculture in India.
In conclusion, the correct statements are 1 and 4. The South-West monsoon in India is primarily caused by the low pressure in the Punjab plain and influenced by the presence of the Himalayas.
