Why Air Moves - Part 1: Pressure Belts

Front

What happens to warm air compared to cool air?

Back

Warm air is less dense and rises.

Front

What is the effect of Earth's tilt on air around the equator?

Back

The air is consistently warmed.

Front

What creates convection currents?

Back

The rising of warm air and sinking of cool air.

Front

What is the main cause of pressure differences in the atmosphere?

Back

Uneven heating of Earth's surface by the Sun.

Front

What is the relationship between air pressure and wind speed?

Back

Greater differences in air pressure speed up the wind.

Front

Define air pressure.

Back

Air pressure is the force exerted by the weight of air above a surface.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases).

Front

Explain the role of the Sun in atmospheric pressure.

Back

The Sun heats the Earth's surface unevenly, causing differences in air pressure.

Front

What is a pressure belt?

Back

A pressure belt is a region of the atmosphere where air pressure is relatively constant.

Front

How do pressure belts affect wind patterns?

Back

Pressure belts create areas of high and low pressure, influencing wind direction and speed.
