Running concurrently with the upper reaches of the ionosphere, ultraviolet solar radiation ionizes oxygen and nitrogen in this zone's F1 and F2 layers, respectively.
Running concurrently with the upper reaches of the ionosphere, ultraviolet solar radiation ionizes oxygen and nitrogen in this zone's F1 and F2 layers, respectively. Almost devoid of ozone, CO2, and H2O, its density is less than one-millionth of ground level air. This site of the auroras is characterized by an increase in temperature from -90 to several thousand degrees Celsius with increasing height. For 10 points, name this region of the earth's atmosphere extending in altitude from 50 to 250 miles between the mesosphere and the exosphere.
