Web7 jul. 2024 · The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24). WebThe density of gases in the mesosphere is low, they are composed of oxygen, carbon dioxide and nitrogen, and their proportions are almost the same as those of tropospheric gases. The main difference between the two layers is the density of the air in the middle layer is lower, the water vapor content is lower, and the ozone content is higher.
