Atmospheric Layers Flashcard

Front

What is the Exosphere?

Back

The outermost layer of Earth's atmosphere, starting around 500 km above the surface, where satellites orbit and it gradually fades into outer space.

Front

What happens in the Exosphere?

Back

Satellites orbit in this layer, and it gradually transitions into outer space.

Front

What is the Stratosphere?

Back

The layer of the atmosphere where the ozone layer is located, and temperatures rise with altitude.

Front

What is the Mesosphere?

Back

The coldest layer of the atmosphere, located between 50–80 km above the Earth's surface, where meteors burn up.

Front

What is the Thermosphere?

Back

The hottest layer of the atmosphere, where temperatures can exceed 2,000°C.

Front

What is the Ozone Layer?

Back

A region of the Stratosphere that contains a high concentration of ozone (O3) and protects the Earth from harmful ultraviolet (UV) radiation.

Front

What is the Troposphere?

Back

The lowest layer of the atmosphere, where weather occurs and where we live, extending from the Earth's surface up to about 8-15 km.

Front

How does temperature change in the Stratosphere?

Back

In the Stratosphere, temperature increases with altitude due to the absorption of UV radiation by the ozone layer.

Front

What is the significance of the Mesosphere?

Back

It is important for burning up meteors, preventing them from reaching the Earth's surface.

Front

What is the boundary between the Troposphere and Stratosphere called?

Back

The Tropopause.
