Layers of the Atmosphere

Front

What are the layers of the Earth's atmosphere?

Back

The layers of the Earth's atmosphere are: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of the atmosphere, where weather occurs and where we live.

Front

What is the stratosphere?

Back

The stratosphere is the second layer of the atmosphere, 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 decrease with altitude and meteors burn up.

Front

What is the thermosphere?

Back

The thermosphere is the fourth layer of the atmosphere, known for its high temperatures and the presence of the ionosphere.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of the atmosphere, where the atmosphere thins out into space.

Front

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

Back

Air pressure decreases as you go higher in the atmosphere.

Front

What is the ozone layer?

Back

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

Front

What is the ionosphere?

Back

The ionosphere is a part of the thermosphere that contains charged particles and is responsible for phenomena like the Aurora Borealis.

Front

What is the role of the atmosphere in temperature regulation?

Back

The atmosphere helps maintain a stable temperature suitable for life on Earth by trapping heat.
