Atmospheric pressure and Types of Winds — Practice Quiz

Air becomes less dense

As altitude increases, air becomes thinner or less dense, resulting in lower pressure.

Less dense than cold air

When air is heated, it expands and becomes less dense, causing it to rise.

Air rises due to intense heating

The equator receives intense solar heating, warming the air, making it light and causing it to rise, creating low pressure.

Air is cold and sinks

Cold air at the poles is dense and sinks, creating high pressure.
