The ozone layer which is responsible for protecting life on earth from harmful UV radiation from the Sun is located in which layer of the atmosphere?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Stratosphere
The ozone layer lies in the stratosphere, the layer above the troposphere, mostly at a height of about 15-35 km. Ozone (\(\ce{O3}\)) there absorbs most of the Sun’s ultraviolet radiation, which would otherwise harm living things, and this absorption also warms the upper stratosphere.
