Define thinning of the atomospheric ozone layer.
Homework Answers
Answer- Thinning of the atmospheric ozone layer is known as ozone depletion which is caused by the release of different chemicals from factories and other human activities. Ozone depletion increases the quantity of ultraviolet radiation that can injure living beings on Earth. Ozone layer is very important to block UV rays and its depletion may cause various dangerous effects on Earth.
