Question

Assertion (A): The air circulation over the oceans in the middle latitudes is mainly anticyclonic.

Reason (R): The oceanic circulation pattern corresponds with the circulation of air.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and Rare true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is the correct explanation of A.

Explanation: 

• Assertion (A): The air circulation over the oceans in the middle latitudes is mainly anticyclonic – True. In the middle latitudes (30°–60° N and S), high-pressure zones dominate over oceans, leading to anticyclonic (clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere) wind circulation.

• Reason (R): The oceanic circulation pattern corresponds with the circulation of air – True. The movement of air (winds) greatly influences the surface ocean currents, as wind-driven circulation follows similar patterns to atmospheric flow.
