Write short notes on stratosphere?

- The stratosphere is the second layer of Earth's atmosphere, located above the troposphere and below the mesosphere.
- It extends from about 10 to 50 kilometers above the Earth's surface.
- The stratosphere is characterized by the presence of the ozone layer, which absorbs and scatters the majority of the Sun's harmful ultraviolet radiation.
- Temperatures in the stratosphere generally increase with altitude due to the absorption of ultraviolet radiation by the ozone layer.
- Commercial airliners typically fly in the lower stratosphere to take advantage of the smoother air and lower fuel consumption.
- The stratosphere plays a crucial role in regulating Earth's climate and protecting life on Earth from harmful radiation.

The stratosphere is the layer of the Earth's atmosphere above the troposphere and below the mesosphere, starting about 10 to 15 kilometers (6 to 9 miles) above the surface of the Earth, and extending to about 50 kilometers (31 miles). Unlike the troposphere, where temperature generally decreases with increasing altitude, the temperature in the stratosphere increases with increasing altitude due to the absorption of ultraviolet radiation by ozone molecules. The stratosphere contains the ozone layer, which shields the Earth's surface from harmful ultraviolet radiation.
