The contracting Earth theory, also called geophysical global cooling, was a nineteenth century geological theory associated with James Dwight Dana that predated plate tectonics. It held that the Earth had originally been molten and that mountains and other crustal features formed as the planet's interior cooled and its volume shrank, forcing the rigid outer crust to crumple. That crumpling of the shrinking crust was offered as the mechanism producing mountain ranges.

In the early 1900s, Professor Eduard Suess used the theory to explain the 1908 Messina earthquake, being of the opinion that the Earth's crust was gradually shrinking everywhere.
