The atmospheric layer that is immediately above the troposphere and contains most of the Earth's ozone. Here temperature increases upward when ozone absorbs solar ultraviolet light, protecting life from harmful electromagnetic radiation (Fig. 1). Ozone is created in sunlight from molecular oxygen, which accumulated as a by-product of hundreds of millions of years of photosynthesis. As the protective ozone layer grew, more plants were able to colonize the land surface. The stratosphere's existence is evidence of life on Earth. See also: Ozone; Photosynthesis; Stratospheric ozone
