Which force causes the trade winds of the southern hemisphere to start blowing from southwest to northeast in India after crossing the equator?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. Coriolis force.
The Coriolis force is responsible for causing the trade winds of the southern hemisphere to shift direction after crossing the equator. As these winds move towards India, they are deflected due to the Earth's rotation. In the southern hemisphere, the trade winds initially blow from southeast to northwest. However, upon crossing the equator, the Coriolis effect causes them to veer to the right, resulting in a southwest to northeast direction, contributing to the onset of the Indian monsoon.
