What is the Theory of Continental Drift?

• There is a gravitational force that is acting on Earth's land masses, pulling them apart at a rate of 1-2 cm per year.

• The continents are located exactly where they will remain for the next 250 million years.

• The Earth was once a molten mass that has since cooled and contracted, separating the continents by vast oceans.

• The continents were once together in one large land mass but they have since drifted apart.
