300 million years ago, all of the land on earth was part of one giant landmass called
pangea.
Pangea was what we call a supercontinent.
Due to the movement of tectonic plates, the landmass split up, and gradually the earths
continents formed as we know them today.
North America on top of south America, Europe next to asia, and Africa and Australia on
their own.
Interesting plot twist, 250 million years in the future, pangea is going to reform,
so that the earth consists of one solid landmass.
Africa is heading toward Europe, Australia and asia will merge, and the atlantic ocean
will completely disappear.
So what if pangea reformed?
That’s what we’re going to talk about, right now on life’s biggest questions.
Hello and welcome back to life’s biggest questions, the channel that questions the
impossible, and occasionally the entirely possible.
I’m charlotte dobre, and if this is your first time here, hit that subscribe for daily
videos on great topics just like this one.
Around 310 million years ago, the earth’s landmass was one giant continent known as
pangea.
This is what the world looked like when pangea was still around.
Eurasia was next to north America, which shared its southern borders with south America and
Africa.
India and antartica were next to each other and right at the bottom was Australia.
But then, 250 million years ago, pangea started to break up.
During the Triassic period, earthquakes and volcanic eruptions caused the pangea to pull
apart.
If pangea reaformed, it would mean all the wildlife and humans will now be able to move
freely around one large landmass.
Its entirely possible that one of the reasons why the dinosaurs went extinct, they were
no longer able to roam freely to other areas of the landmass in search of food or habitiat.
The oceans that separated species caused them to evolve in different ways.
It can be assumed that once the earth has one big landmass again, there will be less
ecological variation.
While pangea itself isn’t going to reform exactly the way it was, in 250 million years,
the earth is going to become one giant landmass once again, but a little different this time.
The earth’s tectonic plates are always moving.
At a rate of a few centimeters per year.
North and south America will become one landmass again.
Africa will share its southern border with north and south America, and its eastern border
with Eurasia.
Then there’s going to be an ocean right in the middle of that landmass.
Antartica, india and Australia could end up underneath.
With little to no ocean separating the continents, the weather is going to be extremely different.
Its likely the land toward the center will be very dry and airid, and the land on the
coast will be temperate.
Then of course, much of our planet will be a big blue ocean.
Africa has been moving toward Europe for 40 million years and that’s because Italy,
Greece and most of the Mediterranean is part of the African plate.
The Mediterranean used to be a much larger ocean, and basically, the present day Mediterranean
sea is what’s left of that.
As Africa moves toward Europe, its going to create a mountain range, much in the way the
alps and the Pyrenees mountains were created.
The plate is going to get crumpled and pushed much higher up.
Who knows, maybe a new worlds tallest mountain will form when this happens, and Everest wont
be the tallest anymore.
This is happening very slowly, according to experts, the plates are moving about the same
rate as how fast your fingernails grow.
So it wont be extremely devastating, but it will cause earthquakes, as it already has
in greese and turkey.
As Africa becomes a part of Europe, borders will become blurred.
Once the Mediterranean sea is gone, people, if we are still around, wont travel by sea
anymore.
They’ll be able to travel across continents by land.
Once Africa and Europe share a border, Its inevitable that Africans and Europeans are
going to cross into each others areas and interbreed.
Australia is slowly moving north, and eventually its going to merge with asia.
It’s also inevitable that this will cause conflict between nations.
Its very difficult to predict how the plates are going to move, but according to geologist
Dr. Christopher Scotese, this is what our earth will look like 250 million years from
now.
There are actually 4 separate predictions for what the future earth will look like.
The first is called novopangea.
The second is Pangea ultima.
The third is Aurica, and the fourth Amasia.
Most expert believe novopangea is the most likely.
Pangea was only the most recent of several supercontintents scientists predicted existed.
Rodina was another supercontinent that existed 750 million to 1.3 billion years ago.
And nuna was the oldest known supercontinent.
It’s just part of living on a planet with tectonic plates.
What should we call the new pangea?
Pangea 2.0? write your responses in the comments.
For now, I’m going to wrap up this video with some comment replies.
These were from my last video, what if steve jobs was still alive today.
Dr Complex – I hope this is demonitized.
Well, sorry to shatter your hopes and dreams but it wasn’t.
Half Cromosome – What if life’s biggest questions stopped answering questions.
Well I would imagine people would stop watching.
Mary joyce is bobo – what if you dated your cousin.
That would be weird.
Sparkcloud- thank you guys for going with a queston that I’ve been asking about.
You’re very welcome, we do look at your suggestions and we do take them seriously.
