Which layer of the atmosphere decreses with increasing height?

In the Earth's atmosphere, the temperature generally decreases with increasing height in the troposphere, which is the lowest layer. This layer extends from the surface up to about 8 to 15 kilometers (5 to 9 miles) above sea level, depending on location. Above the troposphere lies the stratosphere, where temperature begins to increase with height due to the absorption of ultraviolet radiation by the ozone layer.
