Afternoon rains in the equatorial region are the result of influences _______?
0

A. Land Breeze
B. Monsoon
C. Frontal
D. Convectional

A

Convection is the process of heat transfer by the movement of fluids. In the atmosphere, convection is responsible for the formation of clouds and precipitation.

The sun’s heat warms the Earth’s surface, and the warm air rises. As it rises, it cools and condenses, forming clouds. The clouds eventually release their moisture as rain or snow.

Convection is most common in the equatorial region, where the sun’s heat is strongest. The warm, moist air rises and condenses, forming clouds that produce afternoon rains.
