Layers of the Atmosphere

Front

What are the layers of the atmosphere in order from the surface of the Earth to outer space?

Back

Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.

Front

What is the troposphere?

Back

The lowest layer of the atmosphere where weather occurs and where we live.

Front

What is the stratosphere?

Back

The second layer of the atmosphere, above the troposphere, which contains the ozone layer.

Front

What is the mesosphere?

Back

The third layer of the atmosphere, where temperatures decrease with altitude and meteors burn up.

Front

What is the thermosphere?

Back

The fourth layer of the atmosphere, characterized by high temperatures and where the Aurora Borealis occurs.

Front

What is the exosphere?

Back

The outermost layer of the atmosphere, where the atmosphere thins out into space.

Front

Why is it difficult to breathe at higher altitudes?

Back

There is less oxygen as altitude increases and gases in the atmosphere become 'thinner' (less dense).

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 significance of the Aurora Borealis?

Back

It is a natural light display in the thermosphere caused by the interaction of solar wind with the Earth's magnetic field.

Front

How does temperature change with altitude in the troposphere?

Back

Temperature decreases with altitude in the troposphere.
