Continental drift and plate tectonics—the notion that large chunks of Earth's crust slowly but inexorably shift positions—was proposed in 1912 but not accepted until the 1960s. These movements changed the face of the planet—pieces of the continents congealed into the "supercontinent" Pangaea about 335 million years ago and then separated about 175 million ago.
