2. It provides us with different climatic conditions
3. It guards us from various kinds of diseases such as Skin Cancer,Skin burns ,etc caused due to UV rays

Answer 2

Ozone Layer blocks the shortwave ultraviolet radiation wavelength that passes through it. This property give it an important function in protecting the biosphere. If the Ozone Layer were not present then the ionizing ultraviolet rays would destroy most of all the life on earth.

Increased ultraviolet radiation can lead to skin cancer, cataracts, immune deficiency, decrease crop yields and reduced populations of phytoplanktons e.t.c .

Increased ultraviolet radiation can lead to skin cancer, cataracts, immune deficiency, decrease crop yields and reduced populations of phytoplanktons e.t.c .Ozone layer also protects oxygen existing at lower altitude from ill effects of UV rays.
