The first cell is called the __________ __________. At the equator, the ground is intensely heated by the sun. This causes the air to rise which creates a low-pressure zone on the Earth's surface.

The _________ cell occurs at higher latitudes (between 30 degrees and 60 degrees N and 30 degrees and 60 degrees S):

A hot desert is an example of ____________ pressure

This line of latitude lies 23.5 degrees south of the Equator

This line of latitude is approximately 23.5° North of the terrestrial Equator.

This cell extends from between 60 and 70 degrees north and south, to the poles.

As air cools it descends, leading to ________ pressure

__________ is the amount of solar radiation received on a given surface in a given time period.

Warms it ascends, leading to _________ pressure

The air above the Equator is very hot and rises, creating an area of _______ __________
