Who Discovered Plate Tectonics?
Alfred Wegener's theory of continental drift laid the groundwork for the theory of plate techtonics. English geologist Arthur Holmes added more to this theory, proposing that the plate junctions lie beneath the sea. Read More »

What Drives Plate Tectonics?
What drives plate tectonics is a force that we can't see, so we can only speculate that it is gravity, or pressure underneath the earth from the temperature variance between the heat of the center and the cooler surface. For more informatio... Read More »
