What is the meaning of ozone layer depletion?

Answer 1

Stratospheric ozone depletion is a concern because the ozone layer in the stratosphere keeps 95-99% of the suns ultraviolet radiation from striking the earth. Stratospheric ozone depletion is a concern because the ozone layer in the stratosphere keeps 95-99% of the suns ultraviolet radiation from striking the earth.

Answer 2

Depletion is an abnormal reduction in the amount of something. So ozone depletion would be inclusive of a larger than normal ozone hole (there has likely always been a hole of some size in winter/spring), and / or increases in UV-B arriving at the Earth's surface (meaning the path from the Sun to the Earth's surface has less ozone along it to absorb UV-B).

Answer 3

Ozone layer depletion refers to the thinning of the ozone layer in the Earth's stratosphere, primarily caused by human-made chemicals like chlorofluorocarbons (CFCs). This depletion allows more harmful ultraviolet (UV) radiation from the sun to reach the Earth's surface, leading to increased risks of skin cancer, cataracts, and other health and environmental problems. Efforts to reduce the use of ozone-depleting substances have been successful in slowing down this process.

Answer 4

The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.

Answer 5

Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.

Answer 6

Ozone depletion is caused most over Antarctica. It is due to CFC's reacting with it.

Answer 7

From the refrigeration, AC, Aerosol sprays CFC (chlorofluoro carbons) are producing.It is entering the atmosphere.This CFC will release chlorine which breaks ozone into oxygen.

Answer 8

Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.

Answer 9

Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.
