The ozone layer is located in the lower region of the earth’s stratosphere and is a unique form of oxygen.
About 90% of the earth’s ozone can be found in the ozone layer.
The ozone layer acts as a powerful shield against the Sun’s dangerous high frequency ultraviolet rays.
Without the ozone layer, ultraviolet radiation could cause many health problems for humans, from skin irritation to cancer, not to mention harm to all other life.
The ozone layer was discovered by the French physicists Charles Fabry and Henri Buisson in 1913.
