Geography-climate causes of heat and rainfall

How does rain happen by atmospheric circulation?

Sun heats Earth at equator=air rises(warm air=less dense)

Air rises=cools(pressure drops,expansion)

Cooling=condensation clouds form

Droplets combine=heavy=rain

Occurs at equator=low pressure=rainfall

What is heat and how does it affect the atmosphere?

Energy from the Sun warms Earth’s surface

Moves by radiation, conduction, and convection.

Heats the air at the equator, rises, and low pressure drives winds and rain

Cold air at Poles=sinks=high prressure=dry areas
