Air has the Following Properties:
It exerts pressure on us.
When air is heated, it expands and contracts.
Warm air rises, while cooler air sinks towards the earth's surface.
As warm air rises, air pressure drops at that location, allowing cooler air to move in.
The term "wind" refers to the movement of air. Air travels from a high-pressure region to a low-pressure zone.
