The ozone layer is composed of ozone, a molecule made up of three oxygen atoms bonded together. Most of the ozone on Earth accumulates in the stratosphere, a layer of the atmosphere between 15 and 30 kilometers above the Earth's surface. The ozone layer prevents the heat energy reflected by the Earth's surface from being re-radiated into space. This process traps heat on the Earth and keeps it warm.
