Question

what drives tectonic plate movement? coriolis effect convection currents gravity the earths magnetic core

Explanation:

Tectonic plate movement is primarily driven by convection currents in the Earth's mantle. The Coriolis effect influences wind and ocean currents, gravity has a minor role (like slab pull), and the Earth’s magnetic core is related to the magnetic field, not direct plate movement. So the correct option is the one with "convection currents".

Answer:

B. convection currents (assuming the purple option is labeled B; adjust the identifier if the actual labeling is different, but the text is "convection currents")
