Layers of the Atmosphere

Front

What is the Stratosphere?

Back

The second layer of the Earth's atmosphere, located above the Troposphere and below the Mesosphere. It contains the ozone layer.

Front

What is the Thermosphere?

Back

The fourth layer of the Earth's atmosphere, located above the Mesosphere. It is characterized by high temperatures and is where the auroras occur.

Front

What is the Troposphere?

Back

The lowest layer of the Earth's atmosphere, where all weather events occur. It extends from the Earth's surface up to about 8-15 kilometers.

Front

What gas makes up 78% of the Earth's atmosphere?

Back

Nitrogen.

Front

What gas makes up 21% of the Earth's atmosphere?

Back

Oxygen.

Front

What is the Mesosphere?

Back

The third layer of the Earth's atmosphere, located above the Stratosphere and below the Thermosphere. It is where most meteors burn up upon entering the atmosphere.

Front

What is the Exosphere?

Back

The outermost layer of the Earth's atmosphere, where the atmosphere thins out into space. It is above the Thermosphere.

Front

What is the Ozone Layer?

Back

A region within the Stratosphere that contains a high concentration of ozone (O3) molecules, which protect the Earth from harmful ultraviolet (UV) radiation.

Front

How does temperature change in the Troposphere?

Back

Temperature decreases with altitude in the Troposphere.

Front

How does temperature change in the Stratosphere?

Back

Temperature increases with altitude in the Stratosphere due to the absorption of UV radiation by the ozone layer.
