The earth has layers - mainly because dust from our solar system is constantly getting caught in our gravity well - falling to the planet surface - piling on top of and covering up what is already here. Estimates vary, but the USGS says at least 1,000 million grams, or roughly 1,000 tons of material enters the atmosphere every year and makes its way to Earths surface.Source(s): blurtit//
