what are the atmospheric layers in order
Starting from the surface of the Earth, these layers are troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Layers of the Atmosphere. The mass of all the atmospheric layers combined adds up to 1.10231131 Ã 10 19 lbs; approximately 80 percent of which can be attributed to the troposphere alone.n mesosphere, temperature decreases with altitude. It is separated from the thermosphere by the mesopause, which is also the coldest part of the Earth, with a temperature of around -100Â°C (-148.0Â°F). Mesosphere is the layer wherein most of the meteors burn when they enter the atmosphere.
