Derived from the Arabic word ‘Mawsim’ (meaning season), “Monsoon” refers to a seasonal reversal in wind direction. It is essentially a large-scale version of a sea breeze, where the wind blows from sea to land in the summer and from land to sea in the winter due to differential heating of land and water. ANSWER: (B) Change in the direction of winds

Monsoons are periodic winds characterized by a complete reversal of direction from one season to another. During the summer, the land heats up much faster than the ocean, creating a low-pressure zone that draws in moist air from the sea, leading to heavy rains. In the winter, the land cools faster than the sea, creating high pressure that pushes dry air back out toward the ocean. While most famous in South Asia (India), monsoon systems also exist in Africa, Australia and parts of the Americas.
