Theory of how the continents were once grouped into one large land mass that broke apart because of plate movement

Detailed explanation-1: -He hypothesized that all of the modern-day continents had previously been clumped together in a supercontinent he called Pangaea (from ancient Greek, meaning “all lands” or “all the Earth”). Over millions of years, Wegener suggested, the continents had drifted apart.
Detailed explanation-2: -About 200 million years ago, all the continents on Earth were actually one huge “supercontinent” surrounded by one enormous ocean. This gigantic continent, called Pangaea, slowly broke apart and spread out to form the continents we know today. All Earth’s continents were once combined in one supercontinent, Pangaea.
Detailed explanation-3: -The theory of continental drift is most associated with the scientist Alfred Wegener. 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.
Detailed explanation-4: -Finally, about 320 million years ago, there was a major collision, geologically speaking, “when Gondwana, Laurussia, and intervening terranes collided to form the Pangea supercontinent, ” according to the chapter, written by Earth scientists Trond Torsvik, Mathew Domeier and Robin Cocks.
Detailed explanation-5: -About 200 million years ago Pangaea broke into two new continents Laurasia and Gondwanaland. Laurasia was made of the present day continents of North America (Greenland), Europe, and Asia. Gondwanaland was made of the present day continents of Antarctica, Australia, South America.
