- Plate tectonics
- Theory
- Earth's surface was once one land mass
- Lithosphere made up of plates which float on the underlying asthenosphere
- Plates moving because underlying mantle is moving
- Evidence
- Fit between coastlines of continents on opposite sides of the Atlantic ocean (supports idea of single land mass)
- Identical fossils found in South America and Africa, supporting idea of a single land mass
- Magnetic stripes on sea floor, supporting idea of seafloor spreading
- Theory
