The plate tectonics theory states that…

• Continental crust “plows through” oceanic crust

• Seafloors or ocean floors move and carry the continents.

• Earth's lithosphere is composed of a massive slab of rocks called plates which moves at 10 cm a year.

• The relative position and shapes of continents as a result of continuous movement of plates of Earth’s crust.
