Thermal Convection, ridge push and slab pull are believed to be the
processes that cause plate tectonics to move.
Thermal convection is a process when the core of the Earth’s heat is
transferred to Earth’s surface by mantle.
Ridge push is when the mantle wells upward
due to convection and raises the edge of spreading oceanic plates. Since the
plates are higher at the spreading center, they are forced downhill because of
gravity as a result, the ocean floor is flatten.
Slab pull is the part of tectonic plates’
motion which can be accounted for through its subduction.
