• There is also oil that is buried under the sea water and it’s bad because the sea animals get sick and they die in hours.

Atmosphere:

• The Atmosphere has air that covers the entire earth and it keeps the natural gasses away from our house.
• Also the Thermosphere is part of the earth’s Atmosphere because it is above Mesosphere and below the Exosphere.

• Mesosphere: The region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 50 and 80 km in altitude.
• Exosphere: The outermost region of a planet's atmosphere.
