What is Wegener27s hypothesis of continental drift?

Answer 1

There is a theory of continental drift by Wegener. He thought that underneath where we stand (continental crust) is magma (lava). You know sometimes there are lily pads in the pond floating on the water and drifting, bumping, and pulling away from each other? That's just like the theory. Continental crust is divided into 7 different plates. When the plates are moving together, it's called a convergent boundary (convergent sounds like connected). When plates are moving apart, this is called a divergent boundary (divergent sounds like divided). The reason they call it continental drift is because the plates are slowly drifting. Sometimes, instead of convergent boundaries where the plates are slipping under each other and creating mountains and hills, they bump into each other. This causes an earthquake. The exact beginning of an earthquake is called an epicenter. Wegener's theory being supported is called plate tectonics.
