A supercontinent cycle is the break-up of one supercontinent and the development of another, which takes place on a global scale. [4] Supercontinent cycles are not the same as the Wilson cycle, which is the opening and closing of an individual oceanic basin. The Wilson cycle rarely synchronizes with the timing of a supercontinent cycle. [1]
The supercontinent cycle is the quasi-periodic aggregation and dispersal of Earth's continental crust. There are varying opinions as to whether the amount of continental crust is increasing, decreasing, or staying about the same, but it is agreed that the Earth's crust is constantly being reconfigured.
Pangaea is the most recent supercontinent reconstructed from the geologic record and therefore is by far the best understood. The formation of supercontinents and their breakup appears to be cyclical through Earth's history. There may have been several others before Pangaea.
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?
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.
Gondwana (/ ɡ ɒ n d ˈ w ɑː n ə /) [1] was a large landmass, sometimes referred to as a supercontinent.The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian subcontinent.
The authors wrote that, within 250 million years, all the continents will converge to form Earth’s next supercontinent: Pangea Ultima. “A natural consequence of the creation and decay of ...
A new study claims that the origin of bees is tens of millions of years older than previously believed.
