Question

Write brief about ozone
layer​

Answer 1

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation.

It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson.

The ozone layer absorbs 97 to 99 percent of the Sun's medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms near the surface.

In 1976, atmospheric research revealed that the ozone layer was being depleted by chemicals released by industry, mainly chlorofluorocarbons (CFCs).

Concerns that increased UV radiation due to ozone depletion threatened life on Earth, including increased skin cancer in humans and other ecological problems, led to bans on the chemicals, and the latest evidence is that ozone depletion has slowed or stopped.

Answer 2

Answer:

It is a layer which is made up of mainly ozone or O3 which is present in stratosphere. It protects us from Sun's ultraviolet rays by absorbing the UV rays. So in return, we need to protect it. But instead we humans are slowly destroying the layer by releasing harmful gases, we are depleting the ozone layer. So we need to create awareness about this, and stop depletion of ozone layer.

Hope this helps:)
