Earth's Atmosphere

This term, team 4 is leaning about  Earth and space. I can’t wait to fill my brain

with amazing thing. I am very fascinated by all the thing I have learned already.

Troposphere: The Troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth. It's thinnest at the North and South Pole

Stratosphere: The Stratosphere is one of the layers of the atmosphere of the planet Earth. It extends from about 8 km above the poles (18 km above the equator) to about 50 km. In the Stratosphere, the temperature rises with increasing height.

Mesosphere: The Mesosphere is the third and coldest layer of Earth's atmosphere, reaching about 130 degrees below zero. The Mesosphere is also where most meteors, or space rocks and metal, burn up before they can crash to the ground.

Atmosphere: This layer of Earth's Atmosphere is about 319 miles (513 kilometers) thick. That's much thicker than the inner layers of the Atmosphere, but not nearly as thick as the Exosphere.

Exosphere: The air in the Exosphere is very thin, and is made up mostly of helium, and hydrogen. Traces of other gases such as atomic oxygen and carbon dioxide can also be found. The upper level of the exosphere is the farthest point from earth that is still affected by earth's gravity.
