GEOLOGY

Detailed explanation-1: -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-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: -In 1912, German scientist Alfred Wegener proposed that Earth’s continents once formed a single, giant landmass, called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today.

Detailed explanation-4: -Early Gondwana (pre-Pangea, 550-336 mya) Gondwana was something of a miniature supercontinent. It didn’t contain all land on Earth, or even close to it, really. Nearly of Earth’s modern southern hemisphere landmasses were part of Gondwana.

Detailed explanation-5: -Pangea was the last supercontinent, a giant conglomeration of all the continents. It formed 300 million years ago when the tectonic plates that make up Earth’s crust modified and rearranged themselves, bringing the continents together.
