The Atmosphere

Front

What is the troposphere?

Back

The troposphere is the lowest layer of the atmosphere where weather occurs and is heated by the Earth’s surface.

Front

Does temperature vary evenly with altitude in the atmosphere?

Back

Yes, temperature varies with altitude, but not always evenly.

Front

True or False: All layers of the atmosphere have the same role.

Back

False, different layers of the atmosphere have different roles.

Front

What happens to temperature in the mesosphere?

Back

The temperature decreases with height in the mesosphere because it does not absorb ultraviolet radiation from the sun.

Front

Why does the atmosphere have different layers?

Back

The atmosphere has different layers to protect us from ultraviolet radiation and meteors and asteroids.

Front

What is the role of the ozone layer?

Back

The ozone layer absorbs harmful ultraviolet radiation from the sun.

Front

What is the stratosphere?

Back

The stratosphere is the layer above the troposphere where the ozone layer is located.

Front

What is the significance of the thermosphere?

Back

The thermosphere is the layer of the atmosphere where the temperature increases significantly with altitude and is where the auroras occur.

Front

What is atmospheric pressure?

Back

Atmospheric pressure is the force exerted by the weight of air above a given point.

Front

How does altitude affect atmospheric pressure?

Back

As altitude increases, atmospheric pressure decreases.
