Ozone is a major component of the ozone layer, at 10 ~ 50km from the ground the atmosphere the stratosphere, the concentration of the atmosphere, about 90% of the ozone, of which 22 ~ 25km away from the ground to the highest value of ozone concentration, called the ozone layer. If the Earth ozone compressed to 1 atm, its thickness is only 3mm or so, like a "universe of about 3mm thick clothes." With the rapid development of modern industry, the destruction of the ozone layer is also increasing, so the resulting fall in the birth of the Antarctic ozone hole.

Ozone is a major component of the ozone layer, at 10 ~ 50km from the ground the atmosphere the stratosphere, the concentration of the atmosphere, about 90% of the ozone, of which 22 ~ 25km away from the ground to the highest value of ozone concentration, called the ozone layer. If the Earth ozone compressed to 1 atm, with a thickness of only 3mm or so, like a "universe of about 3mm thick clothes." With the rapid development of modern industry, the destruction of the ozone layer is also increasing, so the resulting fall in the birth of the Antarctic ozone hole.
The ozone layer of ozone is the main component in the ground, 50km 10 ~ in the atmosphere, the stratosphere atmosphere approximately 90% of ozone, including 22 ~ 25km away to reach the highest density of ozone, referred to as the ozone layer. If the earth ozone compression to 1 atmosphere, its ply just 3mm around, like a piece of 3mm thick "about YuZhouFu". Along with the rapid development of modern industry, ozone destruction, and the Antarctic ozone hole and then was born.
