Ozone is only a trace gas in the atmosphere, only about 3 molecules – smallest physical unit of a substance, consisting of two or more atoms linked together – for every 10 million molecules of air. But it does a vital job; the Ozone Layer acts like a sponge, it absorbs the bits of radiation hitting Earth from the sun. In other words, it acts as a shield for life on earth.

The ozone layer is a thin part of the Earth’s atmosphere that lies approximately 25 miles above Earth’s surface. It absorbs almost all of the sun’s harmful ultraviolet light. The ozone layer is one layer of the stratosphere, the second major layer of the Earth’s atmosphere. The stratosphere can be described as the mass of protective gases clinging to our planet.
