Detailed Solution

Stratosphere: Within this layer, temperature increases as altitude increases; the top of the stratosphere has a temperature of about 270 K, just slightly below the freezing point of water.

The stratosphere is layered in temperature because ozone here absorbs high energy UVB and UVC energy waves from the sun and is broken down into atomic oxygen (O) and diatomic oxygen. Atomic oxygen is found prevalent in the upper stratosphere due to the bombardment of UV light and the destruction of both ozone and diatomic oxygen.

It is when these two forms of oxygen recombine to form ozone that they release the heat found in the stratosphere.
