Question

Why do the polar winds not move in exact North-South direction?

• A. The revolution of the earth affects the direction of the winds.
• B. The rotation of the earth affects the direction of the winds.
• C. The Other air currents in the atmosphere change the direction of the polar winds.
• D. None of these

Answer 1

The correct option is B The rotation of the earth affects the direction of the winds.

The polar winds do not move in exact North-South direction winds would have flown in the north-south direction from north to south, or from south to north. A change in direction is, however, caused by the rotation of the earth.
