but is also more easily absorbed by the ozone layer. The problem lays at the places that aren’t protected by this layer because of the existence of ozone hole.
the ozone layer is reduced to as little as 100 Dobson units, or about the thickness of a dime. Since it was discovered, this "ozone hole" has grown larger in each successive Antarctic winter before it disappears in the summer.
Life exists on earth because of ozone layer. This layer protects the earth from the harmful UV rays of the sun. As per a recent study, scientists have deeply explored variations in this layer and its depletion in larger amounts in the poles which is commonly termed as ozo...
The term 'ozone hole' refers tothe depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth's polar regions. ... Polar stratospheric clouds create the conditions for drastic ozone destruction, providing a surface for chlorine to change into ozone-destroying form....
The ozone layer is a region in the Earth’s atmosphere that contains high concentrations of ozone. Ozone is three molecules of oxygen bonded together, and so it has the chemical symbol O3. The ozone layer contains more than 91% of the ozone in the Earth’s atmosphere. Because it absorbs ...
