Question

which of the following statements describes mantle convection?
when the molten material beneath the earths crust erupts through the surface.
when the molten material beneath the earths crust moves
when two crustal plates collide
when two crustal plates diverge

Explanation:

Mantle convection is the slow - moving flow of the mantle's semi - molten rock. It involves the movement of molten material beneath the Earth's crust. Eruption through the surface is related to volcanic activity. Plate collisions and divergences are results of plate tectonics influenced by mantle convection but are not the definition of mantle convection itself.

Answer:

When the molten material beneath the Earth's crust moves
