Pangea, 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).

The geography of the continents bordering the Atlantic Ocean was the first evidence suggesting the existence of Pangaea. The seemingly close fit of the coastlines of North and South America with Europe and Africa was remarked on almost as soon as these coasts were charted.
7 de abr. de 2023 · The initial breakup of Pangaea started during the late Ladinian age, about 230 million years ago, with the opening of the central Atlantic. About 175 million years ago, during the Early-Middle Jurassic period, Pangaea began to separate from the Tethys Ocean in the east to the Pacific in the west.

Pangea was once a single unified landmass surrounded by a solitary sea called Panthalassa. Pangea broke apart in three major stages, as rifts appeared within the Earth's crust.
Pangea, supercontinent that incorporated almost all of Earth’s landmasses in early geologic time. Fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago), it began to break apart about 200 million years ago, eventually forming the modern continents and the Atlantic and Indian oceans.
11 de dez. de 2019 · Learn about the supercontinent of Pangea, which covered one-third of the planet and broke apart 200 million years ago to form the continents of today.
Modern geology has shown that Pangea did actually exist. In contrast to Wegener’s thinking, however, geologists note that other Pangea-like supercontinents likely preceded Pangea, including Rodinia (circa 1 billion years ago) and Pannotia (circa 600 million years ago).
