7.E.1.1 Atmosphere Layers Test Review

When cold air is at the tops of mountains, the air

• will flow toward areas of lower pressure in valleys.

• will flow toward areas of higher pressure in valleys.

• is considered to be less dense than warmer air

• is considered to be free of oxygen atoms

An atmospheric layer of a specific gas provides shielding from harmful ultraviolet light from the Sun, allowing life to thrive on Earth. What gas makes up this layer?

• H2O

• CO2

• N2

• O3

The BEST description of the troposphere is the layer of the atmosphere with the

• most ozone

• greatest density

• highest altitude

• coldest temperature

Which BEST explains why air temperatures near mountaintops are often much colder than air temperatures near sea level?

• Large amounts of snowfall decrease the temperature.

• Air near mountaintops is less dense.

• Strong winds near mountaintops decrease temperatures.

• The lack of vegetation at sea level allows the ground to absorb more heat

On Mount Everest the temperature decreases as the altitude increases. The summit of this mountain is in which atmospheric layer? (Hint: It is still in the lowest layer)

• mesosphere

• stratosphere

• troposphere

Which of these statements BEST describes temperature as elevation in the atmosphere increases?

• Temperature remains constant with elevation in the thermosphere

• Temperature remains constant with elevation in the mesosphere.

• Temperature generally decreases with elevation in the stratosphere.

• Temperature generally decreases with elevation in the troposphere.
