'Ozone layer' absorbing ultra - violet radiation exists in which of the atmospheric layer?
Explanation
The ozone layer is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere. The stratosphere is the second major layer of the atmosphere, located above the troposphere and below the mesosphere, extending from approximately 10–15 km to 50 km above the Earth's surface.
- Stratosphere: Contains about 90% of the planet's ozone, primarily in the lower portion (15–35 km). It protects life by filtering harmful UV-B radiation.
- Troposphere: The lowest layer where weather occurs; ozone here is considered a pollutant (smog).
- Mesosphere and Thermosphere: Higher layers where the air is extremely thin and ozone concentrations are negligible.
