GEOLOGY

Detailed explanation-1: -Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called ‘good’ 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: -As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide. UVA is not filtered as significantly by the atmosphere.
