GEOLOGY

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: -From about 300-200 million years ago (late Paleozoic Era until the very late Triassic), the continent we now know as North America was contiguous with Africa, South America, and Europe. They all existed as a single continent called Pangea.

Detailed explanation-3: -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.

Detailed explanation-4: -In 1912, German scientist Alfred Wegener proposed a theory he called continental drift. According to Wegener’s theory, Earth’s continents once formed a single, giant landmass, which he called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today.

Detailed explanation-5: -Past Supercontinents. 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.
