Question

Explain the formation of ozone layer and the reason of its depletion.​

Answer 1

Answer:

ozone is o3 gas and it is formed due to cfc used in refrigerator and perfumes

Answer 2

Explanation:

Ozone is a molecule formed by three atoms of oxygen.

The UV radiations split apart some molecular oxygen (O2) into free oxygen (O) atoms which then combine with the molecular oxygen (O2) to form ozone (O3).

O2 -->O + O

O + O2 --> O3 (ozone).

Ozone depletion is primarily caused by human activities. The main effect of ozone depletion is an increase in UV-B rays reaching the earth's surface.

Causes : chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer. These chemicals are found in cleaning agents, aerosols, insulating foam, and refrigerants. CFCs and halons break down into chlorine and bromine which in turn destroy the ozone layer.
