Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2] It assembled from the earlier continental units of Gondwana , Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
Because Pangaea is the most recent of Earth's supercontinents, it is the best known and understood. Contributing to Pangaea's popularity in the classroom, its reconstruction is almost as simple as fitting together the present continents bordering the Atlantic ocean like puzzle pieces. [4]
There are seven continents in our world today. But 250 million years ago, those continents may have been one giant supercontinent called, Pangaea. How did it break up into the world we know today?
The first eon in Earth's history, the Hadean, begins with the Earth's formation and is followed by the Archean eon at 3.8 Ga. [2]: 145 The oldest rocks found on Earth date to about 4.0 Ga, and the oldest detrital zircon crystals in rocks to about 4.4 Ga, [34] [35] [36] soon after the formation of the Earth's crust and the Earth itself.
Panthalassa, also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [1] was the vast superocean that encompassed planet Earth and surrounded the supercontinent Pangaea, the latest in a series of supercontinents in the history of Earth.
The supercontinent Pangaea surrounded by the superocean Panthalassa. A superocean is an ocean that surrounds a supercontinent.It is less commonly defined as any ocean larger than the current Pacific Ocean. [1]
In the modern day, there are seven continents. However, there have been more continents throughout history. Vaalbara was the first supercontinent. [2] Europe is the newest continent. [3] Geologists have predicted that certain continents will appear, these being Pangaea Proxima, Novopangaea, Aurica, and Amasia.
The flow of heat will be concentrated, resulting in volcanism and the flooding of large areas with basalt. Rifts will form and Pangaea Proxima will split up once more in 400 to 500 million years. Earth may thereafter experience a warming period as occurred during the Cretaceous period, which marked the split-up of the previous Pangaea ...
