What is the theory of plate tectonics?

• The theory that describes how Earth's outer layers is broken up into moving tectonic plates

• Tectonic plates stay in one place

• All of the continents were once apart of a Super Continent called Panthalassa

• All of the plates were once a solid plate until they broke up and moved to their current position
