Layers of the Atmosphere

Which layer contains the ozone layer?

• exosphere                       

• stratosphere 

• thermosphere  

• troposphere

Where will you find the weather balloons?

• exosphere                   

• mesosphere  

• stratosphere 

• thermosphere

Which layer do most clouds form?

• stratosphere

• troposphere

• thermosphere

• mesosphere

Which layer do meteors form?

• mesosphere

• troposphere

• stratosphere

• thermosphere

In which layers does temperature increase with increasing height?

• thermosphere and stratosphere

• mesosphere and troposphere

• stratosphere and mesosphere

• exosphere and troposphere

What causes space rocks to burn in the atmosphere?

• too much heat

• air friction

• ozone

• sunlight

What makes the exosphere so hot?

• It contains a lot of carbon dioxide.

• It is directly exposed to sunlight.

• EM waves become short wavelengths.

• More gases trap heat from the sun.

What makes the troposphere the densest layer?

• Weather exists here.

• Sunlight heats the gases.

• Most gases are found here.

• Ultraviolet rays are absorbed above it.

What makes the mesosphere the least studied layer?

• It is so high that it cannot be reached by Earth scientists.

• Radio signals cannot pass through the mesosphere.

• Air friction burns any aircraft that can reach the layer.

• Weather balloons and aircraft cannot fly high enough to reach this layer.

Why does it feel cold in the thermosphere even though the registered temperature is thousands of degrees Celsius?

• The gases in this layer do not absorb much heat.

• There is a thin atmosphere and gases are far apart.

• There are no gases in this layer that can trap sunlight.

• The clouds that are formed in this layer contain ice crystals.
