Unit 2B Atmosphere and Weather Test Review

Temperature increases as altitude increases in both the stratosphere and the thermosphere. What is the

main difference between these two layers?

• The temperature increases in the stratosphere because of direct exposure to the sun, and in

  the thermosphere because ozone absorbs ultraviolet radiation.

• The temperature increases in the stratosphere because of aurora borealis, and in the

  thermosphere because of the jet stream.

• The temperature increases in the stratosphere because ozone absorbs ultraviolet radiation,

  and in the thermosphere because of direct exposure to the sun.

• The temperature increases in the stratosphere because of the jet stream, and in the

  thermosphere because of aurora borealis.

Most ultraviolet (UV) rays are deflected or absorbed by the atmosphere, but some of these rays pass

easily through the atmosphere and penetrate Earth’s surface. What stops these rays?

• Water

• Chlorofluorocarbon

• Ozone

• Nitrogen

The Earth’s atmosphere is important to living things because of which of the following?

• Provides all the gases that living things need in order to survive.

• It contains dust and other particles.

• Maintains constant relative humidity.

• It is very thin compared to the size of the Earth.

What is the relationship between altitude and pressure?

• The lower the altitude the lower the pressure.

• The higher the altitude the lower the pressure.

• There is no correlation between the two.

• The higher the altitude the higher the pressure.

• Troposphere

• Exosphere

Which atmospheric layer of the atmosphere has the highest density of gas molecules?

• Troposphere

Which is most often a result of a warm air mass moving over a cooler air mass?

• A decrease in wind speed

• A decrease in cloud cover

• An increase in precipitation

What is the main source of energy that drives all weather patterns?

• The sun

• The oceans

• The moon

• The mountains

The arrow on the map below shows the location of an air mass over the Gulf of Mexico. Which are the
