Question

in which layer of the earth does the motion of the convection currents drive plate movement?

lithosphere
inner core
outer core
mantle

Explanation:

Convection currents occur in the mantle. Heat from the core causes the mantle material to circulate. This movement drives the motion of tectonic plates. The inner core is solid, the outer core is liquid but mainly affects the magnetic field, and the lithosphere is the rigid outer layer that moves due to mantle convection.

Answer:

mantle
