The earth is made up of a series of large plates, these are called tectonic plates,like pieces of a large jigsaw puzzle.
The tectonic plates are constantly moving at a rate of a few centimeters per year, and the ocean floors also move as well.
The tectonic plates are moved by convection currents which are below them, this moves the plates in different directions.
