Katen [24]

The correct answer is - plate tectonics.

The convection currents in the mantle, are having very high temperatures and very high pressures.

The very high pressure from bellow manages to push the tectonic plates in certain direction, and even though that movement is only a couple of cm per year, on the long term it has huge effects on everything on the planet.
