Answer the following questions.
(i) Why do the plates move?​

Answer 1

One explanation for the movement of the Earth's crustal plates is believed to be convection currents which occur in the semi-molten mantle. These convection currents are created by heat from within the earth – much of which is generated by radioactive 

Answer 2

Why do plates move? The main driving force of plate techtonics is gravity. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle. This process is called subduction.
