Earth’s surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks of Earth’s crust. This movement may be why life exists here. Earth is the only known planet with plate tectonics and the only known planet with life. Most scientists think …

While plate tectonics may not be absolutely necessary for life, they may be necessary for a technological civilization to arise. Habitability may be possible on a static world, but habitability probably won’t persist long enough for a technological civilization like ours to appear. Plate tectonics regulates our planet’s climate, and without it, atmospheric CO2 would rise to catastrophic levels. New …
