Geothermal Gradient....as you go deeper and deeper into the earth the pressure increases, which in turn increases the temperature...the geothermal gradient. As a plate is subducted (dives under) another plate, the part that is plunging into the crust will eventually be under enough pressure that it will begin to melt. The molten rock is lower in density then the surrounding material, and will migrate towards the surface.
