This perfect aligning of mountain ranges indicated that the continents were once together. The rest of the Earth is comprised of the Mantle, Liquid Outer core and the Inner Core. He called his hypothesis continental drift. Another term for subduction is slab pull which suggests that as the denser oceanic plate is subducted at a convergent margin, they become denser than the underlying mantle and pulls the rest of the plate behind it.
