PLATE TECTONICS
Plate tectonic is the scientific theory that suggests, that the outermost shell of the earth is divided into several plates that move over the mantle and moving constantly due to the extreme pressure and heat coming from underneath the planet.
The theory also states that the outer shell of the earth is broken into multiple pieces or fragments and divided into several plates that move over the semi-liquid composition of the mantle.
