WIND

Front

What happens to air at the poles?

Back

Air at the poles is colder and denser, so it sinks.

Front

What is the process that moves cooler air out and warmer air in during a land breeze?

Back

Convection.

Front

How far do local winds typically blow?

Back

Local winds blow over short distances.

Front

What is the relationship between high pressure and low pressure air?

Back

High pressure air moves in to take the place of low pressure air.

Front

What causes differences in air pressure?

Back

Differences in air pressure are caused by uneven heating of the Earth.

Front

Define convection.

Back

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

Front

What is the role of density in air movement?

Back

Colder, denser air sinks, while warmer, less dense air rises.

Front

What is a land breeze?

Back

A land breeze is a local wind that blows from land to sea, typically occurring at night.

Front

What is a sea breeze?

Back

A sea breeze is a local wind that blows from the sea to land, typically occurring during the day.

Front

Explain the concept of air pressure.

Back

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