What is the convection pattern between 30°S and 30°N latitude? Cooler air rises and moves away from the equator, then warms and falls and moves back to the equator.

Question

Cooler air rises and moves away from the equator, then warms and falls and moves back to the equator.

Hotter air rises and moves away from the equator, then cools and falls and moves back to the equator.
Hotter air rises and moves away from the equator, then cools and falls and moves back to the equator.

Hotter air rises and moves toward the equator, then cools and falls and moves away from the equator.
Hotter air rises and moves toward the equator, then cools and falls and moves away from the equator.

Cooler air rises and moves toward the equator, then warms and falls and moves away from the equator.

Answer 1

The correct convection pattern between 30°S and 30°N latitude is:

Hotter air rises and moves away from the equator, then cools and falls and moves back to the equator.

This describes the general circulation pattern in the tropics, known as the Hadley cell. In this pattern, warm air near the equator rises due to heating from the sun, moves toward the poles at higher altitudes, cools, sinks around 30° latitude, and then flows back toward the equator at the surface, completing the cycle. This process contributes to the trade winds and the overall climate of the tropics and subtropics.
