Wind in the southern hemisphere is deflected towards left

  1. Due to rotation of the earth

  2. Due to temperature

  3. Due to heating

  4. None of these


Correct Option: A
Explanation:

Coriolis force or Coriolis effect is responsible for wind deflection in the right or left direction. It initiates the change in the direction of winds and ocean currents to be deflected left if in the southern hemisphere and right in the northern hemisphere. It is the result of the earth's rotation. Earth is constantly spinning around its axis, from west to east.
