What significant feature is found in the stratosphere?

The stratosphere, which is the second layer of Earth's atmosphere, is characterized by the presence of the ozone layer. This ozone layer is crucial as it absorbs the majority of the Sun's harmful ultraviolet (UV) radiation, protecting life on Earth from its damaging effects. The concentration of ozone is much higher in this layer compared to others, and it plays a vital role in maintaining the temperature structure of the atmosphere by absorbing and heating the stratosphere. This unique feature sets the stratosphere apart from the layers above and below it, where this significant concentration of ozone is not found.
