GEOLOGY

Detailed explanation-1: -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. There are two major types of UV light: UVB and UVA.

Detailed explanation-2: -The ozone layer protects us from potentially harmful ultraviolet (UV) radiation. CAMS monitors stratospheric ozone and provides UV forecasts based on this information.

Detailed explanation-3: -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-4: -The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. The emission of ozone depleting substances has been damaging the ozone layer.

Detailed explanation-5: -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.
