Ozone Layer-effects in the Earth’s atmosphere

Ozone Layer-effects in the Earth’s atmosphere

In the earth surface, the earth surface is reacted to the UV rays and some harmful rays which can effect our human atmosphere and animals. so we are discuss about the “Ozone Layer-effects in the Earth’s atmosphere”. Further wasting any time let gets start and know about the ozone layer effects on earth surface.

Ozone Layer-effects in the Earth’s atmosphere

The formation of ozone in the stratosphere takes place in two steps.

Firstly, the ultraviolet radiation coming from the sun have sufficient energy to split the dioxygen  into two oxygen atom. Secondly, the oxygen atom react with more dioxygen to form ozone.


O2   —hr→     O + O

O + O2     →         O3

The ozone thus formed the ultraviolet rays and is again broken into dioxygen and an oxygen atom and heat is released.

O3     hr →      O2 + O + Heat

In this way ‘Oxygen Cycle’ is completed in the stratosphere.

Ozone layer does not allow the harmful ultraviolet radiations coming from the sun to reach the space of the earth and thus protect life in the earth. So ozone layer is called earth’s protective umbrella.

Depletion of ozone layer:

Due to human activity two types of compound have been responsible for depleting the ozone layer and creating hole into it.

Effects of depletion of ozone layer:

  • With increase in the exposure to ultraviolet radiation due to ozone hole, the chance of skin cancer.
  • Exposure of eye to UV Radiation damages the cornea and lens the eye and may causes contact or even blindness.
  • Exposure of plants to ultraviolet radiation adversely affects the plant proteins and result in the reduction of chlorophyll and harmful mutation.
  • Depletion of ozone layer will upset the heat balance of the earth.
  • Ozone depletion, if not controlled, would cause ecological disturbances, which would adversely affects man & animals.
