Continents During the Triassic Period
What is the driving force behind the movement of the continental plates?
Not everyone agrees on why the continental plates move across Earth—but there are some theories. In general, the continental plates are made of light material that “floats” on the heavier, molten material of Earth’s interior (called the mantle). As the upper part of the mantle circulates and moves, it slowly “carries” the plates around the planet.
