Layers of the Atmosphere

Front

What is the Ozone layer?

Back

A layer in the Earth's stratosphere that contains a high concentration of ozone (O3) molecules, which protects living organisms by absorbing harmful ultraviolet (UV) radiation from the sun.

Front

What percentage of the atmosphere's gas molecules are found in the Troposphere?

Back

Approximately 75%.

Front

What happens to temperature as altitude increases in the Stratosphere?

Back

The temperature increases.

Front

In which layer of the atmosphere does weather occur?

Back

The Troposphere.

Front

Where does most of the heat in the Troposphere come from?

Back

The Earth's surface.

Front

What are the main layers of the atmosphere?

Back

Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Front

What is the function of the Troposphere?

Back

It is the lowest layer of the atmosphere where weather occurs and where most of the Earth's air mass is located.

Front

What is the Stratosphere known for?

Back

It contains the ozone layer and has a temperature that increases with altitude.

Front

What is the Mesosphere?

Back

The layer of the atmosphere above the Stratosphere, where temperature decreases with altitude and meteors burn up upon entering.

Front

What is the Thermosphere?

Back

A layer of the atmosphere characterized by high temperatures and the presence of ionized gases.
