Detailed explanation-1: -Stratospheric ozone is a naturally occurring gas that filters the sun’s ultraviolet ( UV. The sun produces UV, which is commonly split into three bands: UVA, UVB, and UVC. UVA is not absorbed by ozone. UVB is mostly absorbed by ozone, although some reaches the Earth.
Detailed explanation-2: -Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called ‘good’ ozone.
Detailed explanation-3: -Ozone is a thin layer of gas found in stratosphere. It absorbs ultraviolet (UV) rays and protects all forms of life on the Earth’s surface. Q.
Detailed explanation-4: -This is why the ozone layer exists in the lower part of the stratosphere. The lower layer of the atmosphere that immediately surrounds the Earth is called the troposphere. Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation.
Detailed explanation-5: -Ozone in the stratosphere absorbs some of the Sun’s biologically harmful ultraviolet radiation. Because of this beneficial role, stratospheric ozone is considered “good” ozone.
