How did we fix the ozone
WebOzone. In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O 2 ), 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. WebOzone protects us from the sun by interacting with light. It's created when ultraviolet light hits oxygen molecules (O 2) in the stratosphere, splitting the molecules into two atoms of oxygen (O). When this atom encounters another oxygen molecule, the …
