Question

which layer of earth is primarily responsible for mantle convection? crust outer core mantle inner core

Explanation:

Mantle convection occurs within the mantle. The mantle is the layer between the crust and the core. Heat from the core causes the semi - molten rock (magma) in the mantle to move in convection currents. The crust is the outermost layer and is not the site of mantle convection. The outer and inner cores are too deep and their composition (outer core is liquid iron and nickel, inner core is solid iron and nickel) is not directly responsible for mantle convection.

Answer:

Mantle
