keyterm- Stratosphere

Answer 1

The stratosphere is the second layer of Earth's atmosphere, located above the troposphere and below the mesosphere. It is characterized by a stratified temperature profile, with temperatures increasing with altitude due to the concentration of ozone molecules that absorb and scatter incoming solar radiation. The stratosphere also plays a key role in protecting Earth from harmful ultraviolet radiation by containing the ozone layer. Additionally, commercial aircraft often fly in the lower stratosphere to take advantage of the stable air conditions and strong tailwinds.
