Monsoons form due to the difference in heating between land and ocean. In summer, low pressure over land draws in moist air from the ocean, causing rainfall. In winter, high-pressure land pushes dry winds towards the ocean, reversing the direction of wind flow.

Class 7 Social Science Chapter 3 Climates of India question answer
Monsoons result from temperature and pressure differences between land and sea. During summer, the Indian landmass heats rapidly, creating a low-pressure area that pulls in moist air from the cooler oceans. These moisture-laden winds bring heavy rainfall. In winter, the process reverses as the land cools faster, creating high pressure and causing dry winds to blow from land to sea. This seasonal wind reversal is the basis of the southwest and northeast monsoons in India.
