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: -Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago).

Detailed explanation-3: -Many people have heard of Pangaea, the supercontinent that included all continents on Earth and began to break up about 175 million years ago.

Detailed explanation-4: -Nowadays, it’s believed that Pangea was just one of several supercontinents to mass together (and break apart) over the course of geological history. According to the theory, this cycle of breaking apart and coming together happens because of subduction, which occurs when tectonic plates converge with one another.

Detailed explanation-5: -In fact, 250 millions years ago the Earth’s seven continents were all grouped together into a supercontinent called Pangea. Just before the days of the dinosaurs the Earth’s continents were all connected into one huge landmass called Pangaea .
