How do convection cells in Earth's atmosphere cause high and low-pressure belts?
1 Answer
Descending areas of air produce high pressure areas as the atmospheric molecules get squeezed together. Low pressure areas are when the air at the surface is being sucked upwards.
Explanation:
The Earth's big convection cells are either moving area upward in the atmosphere (which tends to produce areas of low pressure and ofter rain) and areas of descending air that gets compressed, heated up and therefore is higher in pressure. The big series of Low pressures along the equator produces the tropical biome while the band of High pressure around 30S and 30N produce dry deserts in this region (like the Sahara, Mexican deserts).
