Which layer contains the ozone layer and what does it do?

Answer 1

This is the stratosphere. There is also ozone in the lower troposphere, but the ozone layer in the stratosphere contains helpful ozone that blocks much of the ultraviolet radiation. Without this layer, life on earth would be very difficult.

Answer 2

The ozone layer is located in the stratosphere, which is the second layer of Earth's atmosphere. It plays a critical role in absorbing the majority of the sun's harmful ultraviolet (UV) radiation, thus protecting life on Earth from the damaging effects of UV rays.
