Our factsheets will give you key information and our science pages provide detailed information. There is also a quiz to test your knowledge.
The ozone layer
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere, it covers the entire planet and protects life on earth by absorbing harmful UV-B radiation.
