Layers of the Atmosphere

Satellites in space allow communication. Communication is an important aspect of daily life that allows us to receive radio signals that transmit to our phones, computers, and TVs. Where is the satellite communication taking place in our atmosphere?

•  Mesosphere

  
  

•  Stratosphere

  
  

• Thermosphere

•  Troposphere

The stratosphere contains the Earth’s ozone layer. The ozone blocks some solar radiation. What would happen if the ozone layer was removed from the atmosphere?

• The removal of the ozone layer would cause higher temperatures.

  
  

•  The removal of the ozone layer would cause an increase in all living populations.

  
  

• The removal of the ozone layer would cause a higher rate of skin cancer.

• The removal of the ozone layer would cause the depletion of natural resources.

Which of the following is not a reason to use a model of the layers of the atmosphere?

• The model allows us to safely observe the atmosphere.

• The model allows us to see all of the layers and their characteristics at once.

  
  

• The model allows to study the layers as models do not have limitations.

• The model allows us to run simulations which may take years to occur naturally

Referencing the diagram above, how does layer C of the atmosphere protect Earth’s surface?

• The mesosphere's thickness helps break down meteors.

• The stratosphere’s thickness helps break down meteors.

• The mesosphere contains the ozone layer which helps absorb the sun's radiation.

• The stratosphere contains the ozone layer which helps absorb the sun's radiation.

Referencing the diagram above, how does layer A support life on Earth?

• The mesosphere’s thickness helps break down meteors.

• The thermosphere shields us from dangerous radiation from the sun.

  
  

• The troposphere contains the gases we breathe and water cycle we depend on.

• The stratosphere contains the ozone layer which helps absorb the sun’s radiation.
