How many tectonic plates are there on Earth?

The Earth is made up of roughly a dozen major plates and several minor plates. The Earth is in a constant state of change. Earth’s crust, called the lithosphere, consists of 15 to 20 moving tectonic plates.

What causes the tectonic plates to move?

The main driving force of plate tectonics is gravity. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle. … The sinking oceanic lithosphere drags the rest of the tectonic plate and this is the main cause of plate motion.
