Atomic oxygen joins regular oxygen molecules to create ozone (O3). This cycle, called the ozone-oxygen cycle, creates an ozone concentration of roughly 2 to 8 parts per million to form the ozone ...

And with that abundant oxygen came ozone. Most of the oxygen in the atmosphere comes in ... This creates a self-reinforcing cycle: With less water vapor in the upper atmosphere, it can’t trap as much ...

In the 1980s, scientists found that chlorofluorocarbons used in aerosol cans and refrigerators were destroying stratospheric ...

will always be present hence the outgoing gas will always be a mixture (see step 3 in the Oxygen – Ozone – Oxygen cycle). The ratio between the outgoing ozone and the oxygen is what constitutes the ...

Their model, the researchers argue, is one step toward a more integrated view of how Earth's crust, mantle and atmosphere interact in the global sulfur cycle ... ozone and very low atmospheric ...

The ozone layer is a section of Earth's atmosphere between 9 and 22 miles (15 and 35 kilometers) above the surface, where there is a high concentration of ozone — an oxygen molecule variant with ...
