10-– Supercontinent,
Back a long time ago when dinosaurs first roamed the Earth, there existed a supercontinent called Pangaea that merged all the countries of the world together into one landmass
But did you know that another supercontinent will form in the next 250 million years?
It’s name will be Pangaea Ultima, including a subduction of the western Atlantic, the destruction of the Atlantic and Indian basin, rejoining America with Africa and Europe – the centre of this giant landmass effectively a semi-arad desert prone to extreme temperatures.
11– Leaving a Mark,

Nuclear tests in the 1950s continuing to this day have thrown dust into the atmosphere circling our planet – most of it falls down as rain and snow, but some gets trapped in glaciers
These glaciers formed over millions of years leave timeline indicators that help scientists date the exact time that piece of ice formed in Earth’s history
Which means when scientists of the future look at our glacier slice, they’ll no doubt shake their heads and whisper a gentle “goddamnit”
That’s IF the glaciers survive their rapid melting from global warming – which they aren’t.
12– Earth Isn’t Round,
For a long time in Earth’s history, people have believed the world is flat and no doubt you’ll find people tell you this even in the comment section of this video
But the Earth isn’t exactly round either – there’s a bulge inside the equator stretching about 20 miles outwards, which actually gives it more of a rotund appearance if you look at it from the right angle
So while it is technically circle, like all bodies that have eaten take away one too many times, the slight gut gives it away
