Ozone layer
01
臭氧层
a layer of gases in the earth's atmosphere that does not let the sun's ultraviolet radiation pass through
Example
The ozone layer is a region of the Earth's stratosphere that absorbs most of the sun's ultraviolet radiation.
Human activities, such as the release of chlorofluorocarbons ( CFCs ), have contributed to the depletion of the ozone layer.
Scientists monitor the ozone layer's thickness and recovery progress using satellite data.
