Ozone in Earth’s Atmosphere


Ozone is a special form of oxygen. Unlike the oxygen we breathe, which is composed of two atoms of oxygen, ozone is composed of three atoms of oxygen. A concentrated ozone layer between 10 and 30 miles above Earth’s surface absorbs some of the harmful ultraviolet radiation coming from the Sun. The amount of ultraviolet light reaching Earth’s surface is directly related to the angle of incoming solar radiation. The greater the Sun’s angle of insolation, the greater the amount of ultraviolet light that reaches Earth’s surface. If the ozone layer were completely destroyed, the ultraviolet light reaching Earth’s surface would most likely increase human health problems, such as skin cancer and eye damage.
80. State the name of the temperature zone of Earth’s atmosphere where the concentrated layer of ozone gas exists. [1]
_______
