Question

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

mantle
outer core
inner core
lithosphere

Explanation:

Convection currents in the mantle drive plate movement. The mantle is a layer of the Earth between the crust and the core. Heat from the core causes the mantle material to circulate (convection). This movement exerts forces on the tectonic plates (which are part of the lithosphere). The lithosphere "floats" on the more fluid - like asthenosphere (a part of the upper mantle). The inner core is solid, and the outer core is liquid but mainly involved in generating the Earth's magnetic field, not directly in plate movement via convection currents like the mantle.

Answer:

mantle
