Over the years the continents drift into new configurations. This is caused by convection in the molten rock of earths mantle to drive the movement of the plates.
Convection in the molten rock of Earth’s mantle drives the movement of the plates. Hotter material rises to the surface, while cooler material sinks toward the core. This creates pushing and spreading apart at mid-ocean ridges and subduction (sinking) of one plate under another at subduction zones.
