University of Toronto study shows that rainfall-induced erosion affects movements of continental plates.
The erosion caused by rainfall directly affects the movement of continental plates beneath mountain ranges, says a University of Toronto geophysicist — the first time science has raised the possibility that human-induced climate change could affect the deep workings of the planet.
“In geology, we have this idea that erosion’s going to affect merely the surface,” says Russell Pysklywec, a professor of geology. “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.”
