The Earth
====The Earth's atmosphere has 6 layers the exosphere,thermosphere,mesosphere,stratosphere**,Ozone,** and troposphere. The exosphere is 300 to 400 kilometers thick and the thermosphere is 80 to 300 kilometers thick the mesosphere is 50 to 80 kilometers thick also the stratosphere is 12 to 50 kilometers thick the Ozone is 30 kilometers thick the troposphere is 12 kilometers thick. In the troposphere all life exists but as you go up the temperature decreases in the stratosphere the temperature slowly gets warmer from about -50 degrees C to 0 degrees C the is mesosphere is -90 deg.C to -130 deg.C.====
