Earth's Atmosphere

Due to lack of trubulence in this layer this is where planes like to fly.

• Troposphere

• Mesosphere

• Stratosphere

• Exosphere

In which layer of Earth’s atmosphere does weather occur?

• mesosphere

• stratosphere

• thermosphere

• troposphere

When a plane flies, it travels through air that contains (has) gases, liquids, and solids. This area is BEST described as the

• atmosphere

• lithosphere

• biosphere

• hydrosphere

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

Why does the troposphere experience (have) the greatest amount of atmospheric pressure compared to the other atmospheric layers?

• It produces the ozone layer.

• It has the highest temperatures.

• It contains a high concentration of gas particles.

• It is the region in which weather occurs.

Which of these statements BEST describes (explains) 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.

Which graph BEST illustrates (shows) the change in density in the lowest layer of Earth’s atmosphere as altitude increases?

• 
• 
• 
• 

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

• H₂O

• CO₂

• N₂

• O₃

Atmospheric greenhouse gases help heat the atmosphere by

• increasing the amount of solar radiation reaching Earth.

• storing energy produced by human activity.

• absorbing infrared radiation released by Earth.

• increasing the average density of air.

On Mount Everest the temperature decreases as the altitude increases. The summit (highest point) of this mountain is in which atmospheric layer?

• mesosphere

• stratosphere

• thermosphere

• troposphere
