what separates the layers of the atmosphere?


I was watching the layers of rhe atnosphere in a google search and it says that there are different layers, but I really don’t understand that separates them. It is the gravity of the earth that creates such phenomenon?

Really, there are no “layers” in the atmosphere, not in the physical sense. There’s the ozone layer, sure, but in terms of the troposphere, stratosphere, etc, it’s a fairly smooth gradient in terms of pressure and atmospheric density — yes, caused by gravity. The names are mostly for human convenience.

Temperature gravity windsheer all effect the layers, however there isn’t a sharp boundary between each layer more a gradual transition.

The “borders” between the layers are extremely fuzzy, but it’s basically the same effect as oil floating on water – the lighter elements exist in heigher concentrations in the upper layers.
