What is the Stratosphere?

Back

The Stratosphere is the second layer of the atmosphere, located above the Troposphere, and contains the ozone layer.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of the atmosphere, where temperatures are the coldest and meteors burn up upon entry.

Front

What is the Thermosphere?

Back

The Thermosphere is the fourth layer of the atmosphere, characterized by high temperatures and the presence of the ionosphere.

Front

What is the Exosphere?

Back

The Exosphere is the outermost layer of the atmosphere, where atmospheric particles are very sparse and can escape into space.

Front

What is the main gas in the atmosphere?

Back

Nitrogen makes up about 78% of the Earth's atmosphere.

Front

What is the ozone layer?

Back

The ozone layer is a region within the Stratosphere that absorbs most of the Sun's harmful ultraviolet radiation.
