The ozone layer resides in the stratosphere, Earth's second atmospheric layer. This protective gas layer warms as altitude increases due to ozone molecules absorbing intense UV energy from the sun. Ozone, a minor component (3 parts per 10 million) of air, has a crucial role. Like a sponge, the ozone layer absorbs solar radiation, shielding life from harmful UV rays. UV light, divided into UVB and UVA, poses DNA damage risk to organisms, making ozone's UV-trapping effect vital for safeguarding Earth's inhabitants.
