Question

Which layer of the atmosphere protects us from harmful uv rays?

Answer 1

In the stratosphere, we find the "good" ozone that protects life on Earth from the harmful effects of the Sun's ultraviolet rays.

Answer 2

Ozone (O3) layer of the atmosphere prevents ultraviolet rays from coming on the surface of earth. Though the thickness varies seasonally and geographically, the ozone layer is found in the lower portion of the stratosphere, from approximately 20 to 30 kilometers above Earth.
