The tectonic plates (initially called continental drift) is the current model of the internal functioning of the Earth. The oceanic plates are located at the Mid Ocean wrinkles. At these places, the oceanic crust is very thin, a few kilometers thick lava happens to clear a permanent move to the surface through large cracks long thousands of kilometers.
This is done to gauge the speed of a few centimeters per year on average and thus Europe and North America were joined there almost 150 million years, were at a distance of another.
