If air is forced far enough upslope, dynamic cooling leads to clouds and precipitation. There may be thin or bright spots in the cloud layer, but no openings. A weather situation in which one layer of air flows over the top of another layer, as when warm air ascends over colder air. It is necessary for almost all forms of animal life. If all the normal content of atmospheric ozone were compressed to sea level pressure, it would form a layer only about one inch thick.
Ozone heats the upper atmosphere by absorbing ultraviolet from sunlight.
It is important because ozone strongly absorbs incoming ultraviolet radiation. An atmospheric layer 9.5 to 15 miles above the Earth s surface in which a high percentage of oxygen exists in the form of ozone. It is important because ozone strongly absorbs incoming ultraviolet radiation.
