Question

What is the reason for the depletion of Ozone layer? What are its effects?​

Answer 1

Answer:

Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.

Answer 2

$\underline{\underline{\sf{Answer}}}$

Ozone layer depletion increases the amount of UVB that reaches the Earth's surface.

Laboratory and epidemiological studies demonstrate that UVB causes non-melanoma skin cancer and plays a major role in malignant melanoma development.
