Some jet airplanes fly in a layer of the atmosphere where temperature generally (mostly) increases with altitude. What is this layer of the atmosphere?

• mesosphere

• stratosphere

• thermosphere

• troposphere

Which graph BEST illustrates (shows) the relationship of altitude and temperature in the lowest layer of the atmosphere of Earth?

• 
• 
• 
• 

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.

In which layer of the atmosphere does MOST of Earth’s weather occur (take place)?

• the exosphere, which is the outermost layer

• the troposphere, which is the lowest layer

• the thermosphere, which has the highest temperature

• the stratosphere, which contains a sub-layer of ozone
