Continental drift is the theory that the planet's continents have shifted over geologic time relative to each other, and they appear to have drifted across the ocean bed. Abraham Ortelius first put forward the notion that continents might have drifted in 1596.
It was then further developed in the initial part of the 20th century, mostly by Alfred Wegener. Wegener said that the continents move around us, and they were joined together as a single supercontinent. During the time Wegner was alive, scientists did not believe this. Wegener collected irrefutable evidence that the continental drift theory was real.
Individual rocks of the same type and age were discovered on both sides of the Atlantic. The eastern US and Canada applications are just like mountain ranges in Greenland, Ireland, Great Britain, and Norway. There were also extinct plants and animals found in the rocks.
