WIND Wind is the movement of air. It is caused by: 1.Differences in temperature. 2.Differences in pressure.

DIFFERENCES IN TEMPERATURE 1. Warm air rises. Warming air make the molecules move faster and spread out. This makes the air less dense. Less dense air is light and will rise.

Differences in Temperature 2. Cold air sinks. Cooling air makes the molecules move slower and group together. This makes the air more dense. More dense air will sink.

DIFFERENCES IN PRESSURE 1. Rising air creates low pressure. If air is lifted up, that means there is Less air pushing down on Earth. 2. Sinking air creates high pressure. If air is sinking, then air is pushing down on the surface of Earth with a high amount of pressure.

The Creation of Wind 1. Differences in temperature cause air to rise and sink all over Earth’s surface. 2. Rising and sinking air creates high and low pressure. 3. The atmosphere does NOT like UNBALANCED PRESSURE SOOOO… IT TRIES TO EQUAL OUT PRESSURE BY MOVING AIR FROM HIGH TO LOW PRESSURE.

Winds are created by … 1. Heating the air, decreases pressure (warm air rises creating a low pressure area). 2. Cool air rushes in to replace the warm air (cooler, denser, air produces high pressure). 3. As air goes from high pressure to low pressure, winds form. 4. Wind is a horizontal movement of air. 5.There are 2 types of winds: local & global.
