Question

what are the causes and effects of ozon depletion ?
​

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

Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders

Answer 2

Answer:

Causes of Ozone Depletion :

• Ozone depletion occurs when chlorofluorocarbons (CFCs)
• Halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere .
• CFCs and halons cause chemical reactions that break down ozone molecules .
• Reducing ozone's ultraviolet radiation-absorbing capacity .

Effects of Ozone Depletion :

• Ozone layer depletion causes increased UV radiation levels at the Earth's surface .
• It is damaging to human health.
• Negative effects include increases in certain types of -

1. Skin Cancers
2. Eye Cataracts
3. Immune Deficiency Disorders.
