Why does warm air rise and move away from the equator?

Equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises When the air cools, it drops back to the ground, flows back towards the Equator, and warm again.

This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises. ... When the air cools, it drops back to the ground, flows back towards the Equator, and warm again.
