Layers of the Atmosphere Review

The two most abundant gases in the atmosphere are

• carbon dioxide and oxygen
• carbon dioxide and nitrogen
• nitrogen and oxygen
• nitrogen and hydrogen

The layers of the atmosphere are classified according to changes in

• altitude
• density
• pressure
• temperature

In which layer does the energy from the sun strike gas molecules, causing them to glow (Aurora Borealis)?

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere

Which layer of the atmosphere has the greatest amount of air pressure?

• troposphere
• stratosphere
• mesosphere
• exosphere

When you increase your altitude, the air pressure 

• increases
• decreases
• stays the same

Layer of the atmosphere that is the coldest:

• troposphere
• stratosphere
• mesosphere
• thermosphere

Layer of the atmosphere most important to a meteorologist:

• troposphere
• stratosphere
• mesosphere
• thermosphere

Layer of the atmosphere where the ozone layer is located:

• troposphere
• stratosphere
• mesosphere
• thermosphere

The layer in our atmosphere in which weather occurs is the

• troposphere
• stratosphere
• mesosphere
• exosphere

As altitude increases in the Troposphere, what happens to the air temperature?

• air temperature increases
• temperature decreases
• temperature fluctuates
• temperature rises
