What Is the Function of the Ozone Layer?
The function of the ozone layer is to shield the Earth from the harmful ultraviolet rays of the sun and to keep the Earth warm. 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.
