Wegener’s continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth must have once been a single supercontinent before breaking up to form several different continents.In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.The theory of continental drift proposes that the continents are drifting away from each other because they are located on tectonic plates, or sections that make up the Earth’s crust, the outermost rigid layer of the Earth. These plates are constantly moving around on the Earth’s surface, like rafts in a pool.

Pangea is a super continent predicted by the theory of continental drift. Scientists believe that about 240 million years ago all the continents were one large one called Pangea. The land of Pangea then broke apart due to tectonic plate movement and moved over millions of years.
Is the continental drift?
Continental drift was a revolutionary theory explaining that continents shift position on Earth’s surface. The theory was proposed by geophysicist and meteorologist Alfred Wegener in 1912, but was rejected by mainstream science at the time.

Which theory came first continental drift or plate tectonics?
In the early 20th century, a scientific theory called continental drift was proposed about this migration of the continents. That theory was initially ridiculed, but it paved the way for another theory called plate tectonics that scientists have now accepted to explain how Earth’s continents move.
What is the theory of plate tectonics?
The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
