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: -Early Gondwana (pre-Pangea, 550-336 mya) 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. In addition, the Arabian peninsula, North Africa, and the Indian subcontinent were part of Gondwana.

Detailed explanation-3: -In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning “all lands"), and over time they have drifted apart into their current distribution.

Detailed explanation-4: -Pangea’s existence was first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning “all the Earth.”

Detailed explanation-5: -Pangaea is only the most recent supercontinent reconstructed from the geologic record. The formation of supercontinents and their breakup appears to have been cyclical through Earth’s history. There may have been several others before Pangaea.
