Question

4. What are the impacts of control measures on levels of ozone depleting substances?

Answer 1

Answer:

Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. But this layer is depleting day by day by absorbing different gases.To protect it we should find out the causes for depleting ozone layer.

Ozone layer depletion is the gradual thinning of the earth’s ozone layer in the upper atmosphere caused due to the release of chemical compounds containing gaseous bromine or chlorine from industries or other human activities
