Question

Assertion (A): The temperature of surface water is higher than the temperature at the bottom of the ocean.

Reason (R): The unequal heating sets up conventional currents in the water bodies.

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 because sunlight heats only the upper layers of the ocean, so the surface water is warmer.
• R is true because unequal heating creates convection currents.
• However, R is not the correct reason for A because convection currents do not explain why deep water stays
