Stratosphere
What is it?
The stratosphere is the layer of the earth's atmosphere that exists between approximately 15 and 50 kilometers above the earth's surface. The stratosphere is between the troposphere and the mesosphere.
Give me an example!
Conditions in the stratosphere are not affected by the water cycle or any other earthly changes in weather. Temperatures in the stratosphere start at about -50 degrees Celsius at the bottom and climb to around 0 degrees Celsius in the upper parts. The stratosphere also contains the earth's fragile ozone layer which has been damaged by chloroflourocarbons.
