The Earth Amosphere

BY: Jevari Sharpe

The stratosphere is a layer of Earths atmosphere. It is the second layer of the atmosphere as you go upward. the troposphere  it is  the lowest layer is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere and the temperature in the stratosphere is -60*c

The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth. The troposphere is wider at the equator (10mi) than at the poles (5mi). and The temperature in the troposphere can reach -80*C

mesosphere is 50 to 80 km long in the lower part of the stratosphere. The temperature drops in this layer to about 100*c. This is the coldest region of the atmosphere. This layer protects the earth from meteoroids. They burn up in this area.

Thermosphere 80 km and up The air is very thin. Thermosphere means heat sphere. The temperature is very high in this layer because ultraviolet radiation is turned into heat. Temperatures often reach 2000*c.

Exosphere the upper part of the thermosphere. It extends from about 550 km for thousands of kilometers. Air is very thin here. This is the area where satellites orbit the earth.At roughly 300 miles from sea level to the top of the thermosphere, the bulk of Earths atmosphere is relatively thin compared to the 8000 mile diameter of our planet.
