PITTSBURGH (KDKA) - I like to think of the atmosphere as sort of a big sandwich since the atmosphere isn't just one layer. It has many distinct layers from the ground all the way into space. This ...

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...
