How big are the tectonic plates
WebIt’s got big slabs of crust called tectonic plates that float on an ocean of slowly flowing rubbery molten rock. These plates move because of heat from Earth’s core. Earth’s radioactive core generates an immense amount of heat that keeps our planet from completely cooling over. Less dense molten rock travels from the core to the surface ... WebEarth's thin outer shell is broken into big pieces called tectonic plates. These plates fit together like a puzzle, but they're not stuck in one place. They are floating on Earth's mantle, a really thick layer of hot flowing rock. The flow of the mantle causes tectonic plates to move in different directions.
