Answer/Explanation:
movement can be cause by the intense heat in the earth's core, which causes molten rock in the mantle layer to move. it moves in a pattern called 'convection cell' which can form when the warm material rises, then cools, and eventually sink down. then the process repeats (cooled, warms up and rises.. etc..)
