The Layers of Our Atmosphere
In order to better understand our atmosphere, scientists have divided it into several layers. These layers are divided based on the characteristics of the gases found at that height. Imagine a layered cake. A layered cake is made out of layers of different ingredients. The first layer might be cake mix. On top of that a cook could put a layer of pudding. On top of that layer they perhaps could put another layer of cake mix, followed by a layer of whipped cream, and so forth. Each layer in our atmosphere is referred to as a sphere.The first layer of the atmosphere is, fortunately, not made out of cake, but rather it is made out of the gases that we breathe everyday. This layer is called the troposphere. The troposphere is the layer that we live in.
