Plate tectonics is the theory that explains how Earth's land masses are in constant motion. Before this theory was discovered, Alfred Wegener found out about the continental drift. Its the hypothesis of how the continents drifted over the ocean bed.
The continental drift led to the theory of plate tectonics. The main reason that led to the movement of the continents is because of the movement of the plates in the lithosphere.
Plates are massive, irregularly shaped slabs of solid rock, generally composed of both continental and oceanic lithosphere.
The intense heat in the Earth's core make the plates to move.
Humans can be affected by volcanic events, sea level rise, and earthquakes, all of which are related to plate tectonics.
