Detailed explanation-1: -It absorbs all the ultraviolet radiations and does not allow them to reach earth’s surface, thus protecting all living organisms from the harmful effects of UV radiations. The ozone layer absorbs the radiation and maintains the natural cycle of oxygen and ozone.

Detailed explanation-2: -The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.

Detailed explanation-3: -Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called ‘good’ ozone. This is in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation.

Detailed explanation-4: -The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin. This then may damage DNA molecules in plants and animals.

Detailed explanation-5: -The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun.
