The surface of this planet is not fixed as it seems but rather broken up like pieces of a jigsaw puzzle. There are enormous plates that move under Earth, this process is called plate tectonic, and it transformed the thinking of geologist everywhere. One of them, Harry Hess, was a factor in figuring out how plate tectonics worked. .
