A
atmosphere
B
ozone layer
C
UV barrier
D
ezone layer
Explanation: 

Detailed explanation-1: -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-2: -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-3: -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-4: -However, scientists now know that UVA light is even more harmful than UVB, penetrating more deeply and causing a deadly skin cancer, melanoma, and premature aging. The ozone layer, Earth’s sunscreen, absorbs about 98 percent of this devastating UV light.

Detailed explanation-5: -The ozone layer protects us from harmful ultraviolet rays of the sun.
