How convection currents affect the plates?

Answer 1

The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.

Answer 2

The heat in the Earth's mantle rises and in return it forces the plates to move which is why the Earth's plates move.

Think of a pot of boiling stew, the chunks move as the liquid boils.

Answer 3

Convection currents in the mantle drive plate tectonics by moving the plates above them. As the mantle heats up and rises near mid-ocean ridges, it pushes plates apart and creates new crust. As the mantle cools and sinks near subduction zones, it pulls plates downward, leading to their descent back into the mantle.

Answer 4

A convection current causes magma to rise at the midocean ridge and pushes the plates apart.
