How does ozone layer protect us from UV rays?

Answer 1

Nitrogen and Oxygen stop UV-C and more energetic radiation. When they do this, they are broken down into constituent atoms.

N2 + energetic light -> 2N

O2 + energetic light -> 2O

Some of the oxygen forms ozone (eventually). Ozone is broken apart by absorbing UV-B and more energetic radiation.

O3 + energetic light -> O2 + O

Answer 2

See "Is UV radiation filtered out by the ozone layer?"

Answer 3

Ozone layer yes blocks radiation. These radiations are from sun and are called UV's.

Answer 4

CFC's are involved in ozone depletion. they react with ozone and deplete them.

Answer 5

The ozone layer acts as a shield. It absorbs the UV rays and prevents them from entering.

Answer 6

Ozone blocks UV rays by decomposing it into oxygen. It is very important process.

Answer 7

When UV hits ozone, it absorbs. It is destroyed and does not travel farther.
