A layer of partially molten rock about 22 to 75 miles underground can't be the only mechanism that allows continents to gradually shift their position over millions of years.
Scientists interested in the construction of the rock layers immediately under the Earth’s crust, the lithosphere and asthenosphere, have new tools to help analyze these layers and further understand plate tectonics.
In a surprising study in Nature, a team led by a Brown University graduate student shows that a sharp boundary exists between the Earthâ€™s hard outermost shell and a more pliable layer beneath, a difference in geological strength underpinning plate tectonic theory. The findings are strong evidence that temperature alone canâ€™t account for differences between the regions, which allow plate tectonics to occur.
