1. True
2. False

Q. Choose the correct statement(s) from the following.

1. Earth spins on its axis from East to West.
2. The points on the equator spin faster than those near the poles.
3. In the northern hemisphere, winds get deflected to the right.
4. Coriolis force does not impact the direction of wind movement.

Q. Assertion (A): Wind gets deflected to the right, in the northern hemisphere and to the left in the southern hemisphere.

Reasoning (R): The earth's rotation is responsible for this.
