The temperature remains fairly constant here. This layer separates the troposphere from the stratosphere. We find the jet stream here. These are very strong winds that blow eastward. This layer contains the ozone layer.
Ozone acts as a shield for in the earth's surface.
It absorbs ultraviolet radiation from the sun. This causes a temperature increase in the upper part of the layer. The temperature drops in this layer to about -100 degrees Celsius. This is the coldest region of the atmosphere. This layer protects the earth from meteoroids.
