Question

Earth is flattened at the poles and bulges at the equator. This is due to the fact that

• A. the earth revolves around the sun in an elliptical orbit,
• B. the angular velocity of spinning about its axis is more at the equator.
• C. the centrifugal force is more at the equator than at poles.
• D. None of these.

Answer 1

The correct option is C the centrifugal force is more at the equator than at poles.

The high centrifugal force at the equator pulls out the water away from the center. As a result, the earth bulges near the equator and is flattened at the top.

The correct option is C.
