Question

state one important function of ozone layer in the atmosphere how is it formed there which compounds are responsible for the depletion ozone layer how do these compounds enter into the atmosphere

Answer 1

Ozone layer help us from UV rays come from Sun IT form by the composition of O3 carbon monoxide carbon dioxide are depletion in ozone layer

Answer 2

One important function of the ozone layer in the atmosphere:

• Harmful ultraviolet rays from the sun are extremely dangerous for all species on the earth.
• The ozone layer in the atmosphere shields the earth from these rays by absorbing them.

Formation of the ozone layer:

• Ozone ($O_{3}$) is formed when three free atoms of oxygen (O) combine.
• Oxygen is present in the form of $O_{2}$ molecules in the atmosphere.
• The sun's ultraviolet rays split these molecules into free atoms which allows them to form the ozone layer.

Compounds responsible for the depletion of the ozone layer:

• Chlorofluorocarbons (CFCs)
• Nitrogenous compounds ( $NO_{2}$ ,  $N_{2}O$ , NO )

Entering of depletion causing compounds into the atmosphere:

• Refrigerators, solvents, air-conditioners, spray aerosols, etc. release harmful CFCs into the atmosphere.
• Nitrogenous compounds are released into the atmosphere during combustion.
