Q:

What atmospheric layer contains the most ozone?

A:

Quick Answer

The ozone layer contains about 90 percent of Earth's ozone. It is part of Earth's stratosphere and lies between 6 and 30 miles above the planet's surface, according to the Environmental Protection Agency. The highest concentration of ozone is found between 12 and 19 miles above the surface, notes Wikipedia.

Full Answer

The ozone layer absorbs from 97 to 99 percent of medium-length ultraviolet radiation from the sun, protecting life on Earth from UV radiation's harmful effects, according to Wikipedia. It is normally thinnest at the equator and thickest at the poles. It also varies with the seasons, and it is thicker in the spring than in the autumn. Ozone is depleted by free-radical catalysts from natural sources and man-made chemicals, such as chlorofluorocarbons and bromofluorocarbons.

  • Q:

    What damages the ozone layer?

    A:

    The atmospheric release of chlorofluorocarbons and hydrofluorocarbons causes a depletion of the ozone layer. When these chemicals reach the stratosphere, they react with UV light, releasing chlorine atoms that break apart ozone molecules.

  • Q:

    How can we protect the ozone layer from being destroyed?

    A:

    In order to halt the depletion of the ozone layer, countries around the world have banned the use of chlorofluorocarbons and other ozone-depleting substances. These compounds produce chlorine and bromine atoms high in the atmosphere, and these atoms react with ozone, destroying it.
