UPSC Prelims PYQ 2010: Cause of wind deflection in Southern Hemisphere
What causes wind to deflect towards the left in the Southern Hemisphere?
- Temperature
- Magnetic field
- Rotation of the earth
- Pressure
Explanation
Option (c) is correct
- The deflection of winds is caused by the Coriolis force, which arises due to the rotation of the Earth. In the Southern Hemisphere, this force deflects moving air to the left, while in the Northern Hemisphere, it deflects winds to the right. Temperature, pressure and magnetic field do not directly cause the directional deflection of winds.
Answer: (c) Rotation of the Earth
