QUESTION:

29. - 30. Ozone layer is the layer in the earth's stratosphere at an altitude of about 6.2 miles (35 km) containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun. What makes it important? And why should we save and protect the ozone layer?

ANSWER:

Why is Ozone Layer important?

Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life. With a weakening of the Ozone Layer shield, humans would be more susceptible to skin cancer, cataracts and impaired immune systems.

Why we should protect ozone layer?

Because it absorbs most of the sun's ultraviolet radiation (UV-B), limiting the amount of this radiation that reaches the surface of the Earth, this radiation causes skin cancer and cataracts, the ozone layer plays an important role in protecting human health.

Ultraviolet radiation from the sun is absorbed by ozone in what layer?

It is the stratosphere, or the part of it called the ozone shield that absorbs most of the sun's UV rad. It has a high concentration and composition of ozone ( 3 atoms of oxygen ) where it splits when it is hit by UV rad making it less harmful.
