Which of the following provides the best explanation as to why convection currents in the mantle cause tectonic plate movement?
A.
Warm, less dense material rises: while cool more dense material sinks. This creates convection currents which cause the tectonic plates to move.
B.
Warm, more dense material rises; while cool, less dense material sinks. This creates convection currents which cause the tectonic plates to move.
C.
Cool, less dense material rises; while warm, more dense material sinks. This creates convection currents which cause the tectonic plates to move.
D.
