Detailed explanation-1: -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-2: -The continental drift hypothesis, the foundation of Plate Tectonics theory was developed in the early part of the twentieth century, mostly by Alfred Wegener who proposed that continents move around on Earth’s surface and that they were once joined together as a single supercontinent called Pangaea.
Detailed explanation-3: -The three most recent supercontinents were Pangea, Gondwana, and Pannotia. Geologists think there were other supercontinents before these three, which are called Nuna (or Columbia), Rodinia, and Ur. One definition of a supercontinent is a single landmass that contains at least 75% of all land on Earth.
