What is the BEST explanation that accounts for the climate in tropical areas near the equator? A) When the air is cooled it can absorb more moisture, and it tends to rise. Thus air near the poles, heated by the direct rays of the sun, absorbs moisture and rises.
B) When the air is warmed by the sun it can absorb more moisture, and it tends to rise. Thus air near the poles, heated by the direct rays of the sun, absorbs moisture and sinks.
C) When the air is cooled it can not absorb as much moisture, and it tends to sink. Thus air near the equator, heated by the indirect rays of the sun, absorbs no moisture and sinks.
D) When the air is warmer by the sun it can absorb more moisture, and it tends to rise. Thus air near the equator, heated by the direct rays of the sun, absorbs moisture and rises. Higher in the atmosphere the air cools again, forming clouds that produce rainfall.
