Gas particles are not found in which region above earth

The earth's atmosphere consists of a layer of different gases held in place by gravity. the atmosphere protects earth by absorbing solar radiation, retaining heat, and regulating temperature extremes. the atmosphere has five different levels: the exosphere, the thermosphere, the mesosphere, the stratosphere, and the troposphere. since there are so many layers and we are limited in space, below are a few ideas to get you started as well as an equation below to you calculate for each layer's weight, which is actually called density.
