Interesting facts #198 ~ Pangaea: Earth’s ancient supercontinent…
Pangaea was a massive supercontinent that formed between 320 million and 195 million years ago. At that time, Earth didn't have seven continents, but instead one giant one surrounded by a single ocean called Panthalassa...

In 1885, Eduard Suess showed how the continuity of mountains on southern continents meant that they were once a single supercontinent. #Poetry #Science #History #Geophysics #Supercontinent #Suess (https://sharpgiving.com/thebookofscience/items/p1885.html)

"they were previously thought to have emerged on the #supercontinent #Gondwana, in what is present-day #Australia. However, the new study indicates their common ancestor may have originated in the northern hemisphere, on the supercontinent #Laurasia, before spreading out further into the world."
Nice overview here. I’m particularly pleased that they acknowledge the uncertainty about what #supercontinent will form next: too many stories present one of the possibilities (usually #Pangaea #Ultima) as a near-certainty. We know for sure that there is at least one more supercontinent in #Earth’s future, and probably more, before plate #tectonics stop entirely in a billion years or so. Everything else is informed speculation at best. All this has happened before …

This is what Earth’s continents will look like in 250 million years
Only a fraction of the planet’s surface will be habitable to mammals when the next supercontinent, Pangaea Ultima, forms.
Pangaea Ultima is expected to form in about 250 million years, when a land mass comprising Europe, Asia and Africa merges with the Americas.

To form pink diamonds, build and destroy a supercontinent
Most of the world’s pink diamonds may have emerged from the breakup of the supercontinent Nuna

The world's largest source of natural diamonds formed when an ancient supercontinent broke up, and there may be more like it waiting to be discovered.
