University of Toronto (2006, April 20). Impact Of Rainfall Reaches To Roots Of Mountains. ScienceDaily Citat: "...The erosion caused by rainfall directly affects the movement of continental plates beneath mountain ranges, says a University of Toronto geophysicist...Diagram showing plate movements due to erosion...“These are tiny, tiny changes on the surface, but integrating them over geologic time scales affects the roots of the mountains, as opposed to just the top of them,” says Pysklywec. “It goes right down to the mantle thermal engine — the thing that’s actually driving plate tectonics. It’s fairly surprising — it hasn’t been shown before.”..."
