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.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R does not explain A.
- A is true but R is false.
- A is false but R is true.
Answer
Both A and R are true and R is the correct explanation of A.
Explanation — Ocean currents are greatly influenced by the stresses exerted by the prevailing winds and Coriolis force. The oceanic circulation pattern roughly corresponds to the Earth's atmospheric circulation pattern. The air circulation over the oceans in the middle latitudes is mainly anticyclonic. Hence, the oceanic circulation pattern also corresponds with the circulation of air.
