Which factor activates a convection current, starting the flow of a fluid?

A. Temperature differences in the mantle.

B. Heated liquids at Earth’s surface.

C. Iron-rich rocks in the mantle.

D. Cold temperatures at the north pole.

Convection is a form of heat transfer in fluids resulting from the movement of the molecules of the medium. Differences in temperature affects the density and makes hotter fluids to flow readily. The hot fluids rises to the surface whereas the cold fluids sinks deeper into the mass.

Mantle convection is a very important process that furnishes the movement of plates on the earth surface.
Cold part of the mantle sinks further deeper and hot part rises.
This sets up a convection cell within the mantle which drives the plates that sits on them.
