Explein protective umbrella as ozone for UV from earth

Answer 1

Explanation:

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentration of ozone $O_3$in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9.3 to 21.7 mi) above Earth, although its thickness varies seasonally and geographically.

Answer 2

It does not allow the harmful UV radiations coming from the sun to reach the surface of the earth and thus protects life on the earth. This ozone layer is also called earth protective umbrella.✔✔
