Layers of the Atmosphere

Front

What are the main layers of the atmosphere?

Back

The main layers of the atmosphere are the 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, where the ozone layer is located.

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, 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 the air is very thin and satellites orbit.

Front

What is the Tropopause?

Back

The Tropopause is the boundary between the Troposphere and the Stratosphere.

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 happens to temperature in the Troposphere as altitude increases?

Back

In the Troposphere, temperature decreases as altitude increases.

Front

What is the role of the ozone layer?

Back

The ozone layer, located in the Stratosphere, protects the Earth from harmful ultraviolet (UV) radiation.
