7.E.1.1 Layers of Atmosphere Review

Which gas can be dangerous in the troposphere, but is helpful at blocking the sun's UV rays in the stratosphere?

• nitrogen

• ozone

• carbon dioxide

• water

Think about the layers of the atmosphere as you move away from the surface of Earth, what happens to the pressure?

• Pressure increases as altitude increases

• Pressure decreases as altitude increases

• Pressure stays the same as altitude increases

What happens to temperature in the troposphere as you increase altitude?

• temperature decreases

• temperature increases

• temperature remains the same

What happens to temperature in the stratosphere as you increase altitude?

• temperature decreases

• temperature increases

• temperature remains the same

What happens to temperature in the mesosphere as you increase altitude?

• temperature decreases

• temperature increases

• temperature stays the same

What happens to temperature in the thermosphere as you increase altitude?

• temperature decreases

• temperature increases

• temperature remains the same

Think about all the layers of the atmosphere, which layers have temperature decreasing as you increase altitude?

• troposphere and stratosphere

• troposphere and mesosphere

• troposphere and thermosphere

• stratosphere and thermosphere

Thinking about the layers of the atmosphere, which layers show increasing temperatures with increasing altitude?

• all of them

• troposphere and thermosphere

• stratosphere and mesosphere

• stratosphere and thermosphere

Which gas is most common in all the layers of the atmosphere combined?

• carbon dioxide

• oxygen

• argon

• nitrogen

Thinking about all of the layers of the atmosphere, what does the troposphere have to support life that is not found in other layers? (select all that are correct)

• high density of air molecules

• temperatures that are not too hot or cold

• water in all 3 phases of matter

• large volume of air for molecules to spread out in
