Match each statement with a layer of the atmosphere. There will be two statements for each layer.

The biosphere interacts most with this layer.
It is the second layer from Earth's surface.
It contains layers of single, unmixed gas.
This layer is where most meteor showers occur.
It is heated by the ozone layer beneath it.
It contains the ionosphere and exosphere.
Winds are strong and steady in this layer.
This layer can have thunderstorms or clear, sunny skies.

The troposphere:

H. This layer can have thunderstorms or clear, sunny skies.

D. This layer is where most meteor showers occur. 

The thermosphere :

F. It contains the ionosphere and exosphere. 

C. It contains layers of single, unmixed gas. 

Explanation:

Depending on the Earth's  temperature the atmosphere can be separated into layers. The troposphere, the stratosphere, the mesosphere and the thermosphere are those layers. The lowest layer is named as Troposphere (0-10 km from the Earth outer surface), it comprises about 75% of the atmosphere's total air and nearly most the water vapor.

Stratosphere (10-30) includes much of the surface ozone. The change in height temperature arises as this ozone absorbs ultraviolet (UV) radiation from the sun. The temperature in Mesosphere (30-50 Km) declines again with height, hitting a minimum of about -90 ° C at the "mesopause." Above this thermosphere (50-400 Km) is settled which is a area where temperatures rise with height once again. The penetration of intense  UV and X-ray radiation from the sun induces this temperature rise.
