Há 5 dias · 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 first breakup of Pangaea is proposed for the late Ladinian (230 Ma) with initial spreading in the opening central Atlantic. Then the rifting proceeded along the eastern margin of North America, the northwest African margin and the High, Saharan and Tunisian Atlas Mountains.
German meteorologist Alfred Wegener first presented the concept of Pangea (meaning “all lands”) along with the first comprehensive theory of continental drift, the idea that Earth’s continents slowly move relative to one another, at a conference in 1912 and later in his book The Origin of Continents and Oceans (1915).
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.
