Question

What caused wind to deflect towards left in Southern Hemisphere?

Answer & Solution

Answer: (Detailed Solution Below)

Option C: Coriolis force

Detailed Solution:

The correct answer is “Coriolis force”.

The Coriolis force is responsible for the deflection of wind in the atmosphere. Due to the rotation of the Earth, moving air (or any moving object) is deflected.

In the Southern Hemisphere, the Coriolis effect causes winds to be deflected to the left of their original path. In the Northern Hemisphere, the Coriolis force deflects winds to the right.

This deflection occurs because the Earth is rotating, and the Coriolis effect is a result of this rotation. It affects all moving objects, including winds, currents, and even airplanes.
