QN008806

If warm surface water from the equator stopped moving toward the poles, the most likely result would be:

(A) Smaller temperature differences globally
(B) Greater temperature differences globally
(C) No change in climate
(D) Increased rainfall everywhere

Correct Answer: B

Explanation:

Heat redistribution would decrease, increasing temperature contrasts.

QN008813

Uneven heating of Earth ultimately contributes to climate regulation because it drives:

(A) Only local winds
(B) Only ocean currents
(C) Movement of air and water on different scales
