Question

Samuel puts a pot of water on the stove to boil and remembers when his teacher taught the class about convection, which is fluid movement driven by heat. Samuel recalls that convection in the Earth’s mantle involves the movement of A.water currents. B.molten materials. C.tectonic plates. D.the lithosphere.

Answer 1

The answer is B. It is B because in if convection currents cooled down then the earth would die.

Answer 2

Answer: Molten materials

The convection can be defined as the heat transfer in liquid. The liquid inside the earth moves in a circular motion and in this way heat transfer takes place.

The hotter liquid moves up and the cold liquid takes place of the hotter particles and it looks exactly like a circular movement of liquids.

The movement of molten material is driven by the heat inside the earth.
