Question

Assertion (A): Coriolis effect increases from the equator towards the poles.

Reason (R): The speed of rotation decreases towards the poles.

Options

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true but R is not the correct reason for A.

Explanation:

• A is true: Coriolis effect is weakest at the Equator and becomes strongest at the poles.
• R is true: The Earth’s rotational speed is highest at the Equator and decreases toward the poles.
• But R is not the correct reason: The Coriolis effect increases because it depends on latitude, not on the change in rotational speed.
