I present some simple ways in which physicists can help decode clues from the chemistry of magma and from the magma transport process itself. Using a simple set of coupled differential equations to represent the transport process, I argue that there may be very special circumstances required to actually heat, weaken, and destabilize a continental plate by flushing it through with molten material. I will end by speculating on some examples from Earth history where such destabilization may have occurred, such as the break up of supercontinents. Most importantly, my talk will outline some key problems that remain unanswered and how physicists can help model and interpret noisy Earth science data.
