Layers of the Atmosphere

Front

What is the Troposphere?

Back

The lowest layer of the atmosphere where weather occurs and most water vapor is found. It has the greatest air pressure because it contains the most molecules.

Front

What is the Stratosphere?

Back

The layer of the atmosphere above the Troposphere, which contains the ozone layer that absorbs harmful ultraviolet rays.

Front

What is the Mesosphere?

Back

The layer of the atmosphere above the Stratosphere, where temperatures decrease with altitude and meteors burn up upon entering this layer.

Front

What is the Thermosphere?

Back

The hottest layer of the atmosphere, characterized by very thin air and temperatures that can rise significantly. It eventually fades into space.

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 radiation.

Front

What happens to air pressure as you go higher in the atmosphere?

Back

Air pressure decreases as altitude increases because there are fewer air molecules at higher elevations.

Front

What is the significance of the Troposphere for weather?

Back

The Troposphere is where all weather phenomena occur, including clouds, rain, and storms.

Front

How does temperature change in the Stratosphere?

Back

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

Front

What is the boundary between the Troposphere and the Stratosphere called?

Back

The Tropopause.

Front

What is the boundary between the Stratosphere and the Mesosphere called?

Back

The Stratopause.
