WebSeafloor spreading is the mechanism for Wegener’s drifting continents. Convection currents within the mantle take the continents on a conveyor-belt ride of oceanic crust that over millions of years takes them around the planet’s surface.

On one side, the oceanic crust is subducted below the continental crust. On the other side, the two plates collide in a transform boundary, which is a horizontal type of movement. The latter is the closest we really come to continents drifting. flip open utility knife
