WebbThe exosphere is the second, outer layer of the thermosphere i. The exosphere lies beyond about 500-1,000 km and is characterized by increasing hydrogen and helium content, because the oxygen and nitrogen that dominate the lower atmosphere have been dissociated into ions in the ionosphere. WebbThe stratopause caps the top of the stratosphere, separating it from the mesosphere near 45–50 km (28–31 miles) in altitude and a pressure of 1 millibar (approximately equal to 0.75 mm of mercury at 0 °C, or 0.03 inch of mercury at 32 °F). In the mesosphere, temperatures again decrease with increasing altitude.
