Question

Which layer of the Earth's atmosphere protects us from Sun's ultraviolet rays?
a. Carbon Layer
b. Ozone Layer
c. Nitrogen Layer

Answer 1

Ozone protects us from Sun's ultra violet rays.

>> Ultra violet rays are direct rays which are emitted by sun to Earth.

>> These rays are very dangerous if they fall on our body.

>> These rays causes skin cancer and also results to the bone melting.

>> Ozone is a gas blanket which absorbs these rays and sends good rays to Earth.

>> But now - a - days ozone layer is duplicating.

>> There is a hole formed in the ozone layer in the area of Antarctica.

>> The causes for the ozone duplication are CFCs { Chloro Fluro Carbons } which are released from refigirators, Air conditioners, sprays etc.

>> We should reduce the usage of these things to protect our ozone layer.

Answer 2

HI

The ozone layer of the Earth's atmosphere protects us from the Sun's UV (Ultraviolet) Rays.

So, option b. is the correct answer.

✨ More to know...

▶️The ozone layer was discovered by Charles Fabry and Henri Buisson, French physicists, in 1913.

▶️UVB radiation can cause immune system suppression, cataracts, genetic damage and even skin cancer.

▶️The ozone layer has been damaged by substances known as chlorofluorocarbons (CFCs) which were used in a variety of products such as insulating foam, solvents, and refrigerants.
