Layers of the atmosphere

Front

What is the troposphere?

Back

The lowest layer of the atmosphere where weather occurs and temperature decreases with altitude.

Front

What happens to temperature in the troposphere as altitude increases?

Back

Temperature decreases.

Front

What is the stratosphere?

Back

The layer above the troposphere where the ozone layer is located and temperature increases with altitude.

Front

What is the mesosphere?

Back

The layer above the stratosphere where meteors burn up and temperature decreases with altitude.

Front

What is the thermosphere?

Back

The layer above the mesosphere where temperature increases significantly with altitude and contains the ionosphere.

Front

What is the exosphere?

Back

The outermost layer of the atmosphere with the lowest air pressure, where atmospheric particles are very sparse.

Front

How does air pressure change with altitude?

Back

Air pressure decreases as altitude increases.

Front

How does density change with altitude?

Back

Density decreases as altitude increases.

Front

What is the ozone layer?

Back

A region in the stratosphere that absorbs most of the Sun's harmful ultraviolet radiation.

Front

What is the ionosphere?

Back

A part of the thermosphere that is ionized by solar radiation and is important for radio communication.
