Question

The Sun emits ultraviolet rays which are harmful for us. A protective layer in the
atmosphere prevents these ultraviolet rays from entering the Earth. This protective layer is depleting slowly due to human activities. Which layer is this and how we prevent its
depletion? Suggest any four ways.

Answer 1

Answer:

Most of Earth's ozone resides in the stratosphere, the layer of the atmosphere that is more than 10 kilometers (6 miles) above the surface. About 90% of atmospheric ozone is contained in the stratospheric “ozone layer”, which shields Earth's surface from harmful ultraviolet radiation emitted by the Sun.
