Back

Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere.

Front

What layer of the atmosphere contains the Aurora Borealis?

Back

Thermosphere.

Front

Why does it become difficult to breathe at higher altitudes?

Back

Gases in the atmosphere become 'thinner' (less dense) as altitude increases.

Front

What is the least dense layer of the atmosphere?

Back

Exosphere.

Front

Why is Earth's atmosphere important?

Back

Life on Earth could not exist without it.

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 layer above the Troposphere, containing the ozone layer which protects us from harmful UV radiation.

Front

What is the Mesosphere?

Back

The layer above the Stratosphere, where temperatures decrease with altitude and meteors burn up.

Front

What is the Thermosphere?

Back

The layer above the Mesosphere, 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.
