Detailed explanation-1: -In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone.
Detailed explanation-2: -Oxygen was also responsible for formation of the ozone layer in the atmosphere. The UV radiation from the sun split oxygen molecules (O2) into 2 atoms of oxygen, which then reacted with another oxygen molecule to generate ozone (O3).
Detailed explanation-3: -Atmospheric oxygen from photosynthesis also forms the ozone layer, which protects organisms from harmful high-energy ultraviolet (UV) radiation from the Sun.
