Ozone in the upper atmosphere is formed mainly through the action of ultraviolet radiation, which breaks down oxygen molecules into individual atoms that can react to create ozone. This process occurs in the stratosphere, where the ozone layer plays a critical role in protecting life on Earth from harmful UV rays.

Ozone is formed in the upper atmosphere primarily by the action of ultraviolet radiation on oxygen molecules. This radiation splits O2 into individual oxygen atoms, which then combine to form ozone. The ozone layer is essential for protecting life on Earth from harmful UV rays. ;
