Seasonal wind reversal is the main basis of what?

Answer and explanation

Correct answer: Monsoon

Direct answer: Option A, monsoon. Monsoon is a seasonal wind system in which the prevailing wind direction reverses between seasons. In the summer season, heating over land and related pressure differences help draw moisture-bearing winds toward the land in South Asia. In winter, the general direction changes. This seasonal reversal is a defining basis of the monsoon, although the complete monsoon system also involves pressure, land-sea heating, relief and moisture. Option A is correct. Option B, earthquake, is caused by sudden movement in the Earth’s crust, not seasonal winds. Option C, volcano, involves molten material and eruptions, not wind reversal. Option D, river erosion, is caused mainly by running water wearing away land, not by the seasonal reversal itself. Memory cue: monsoon equals seasonally reversing winds.
