Layers of Atmosphere

Front

What is the troposphere?

Back

The lowest layer of the atmosphere where weather occurs and where air pressure is highest.

Front

What is the stratosphere?

Back

The layer above the troposphere, characterized by a temperature increase with altitude and containing the ozone layer.

Front

What is the mesosphere?

Back

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

Front

What is the thermosphere?

Back

The layer above the mesosphere, known for its high temperatures and where the auroras occur.

Front

What is the exosphere?

Back

The outermost layer of the atmosphere, where air is extremely thin and satellites orbit the Earth.

Front

What is the greenhouse effect?

Back

The process by which the atmosphere traps the sun's radiation, keeping the Earth warm and livable.

Front

How does temperature change in the troposphere with altitude?

Back

In the troposphere, the temperature decreases as altitude increases.

Front

Why is the ozone layer important?

Back

It shields the Earth from harmful ultraviolet (UV) rays from the sun.

Front

What is air pressure?

Back

The force exerted by the weight of air above a given point, highest in the troposphere.

Front

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

Back

Air pressure decreases as altitude increases.
