10 Facts about the ocean you didn’t know
The ocean makes up around 70% of the earth’s surface, yet it is shrouded in mystery. Perhaps this is what attracts us to it – the vast possibility, the adventure, the unknown.
Today, we’re sharing 10 facts you didn’t know about the ocean.
Only 5% explored
It’s absolutely mind blowing to think that only 5% of the ocean has been explored. This obviously means there is so much we don’t know about the creatures and life that lives below.
1,000 year journey
The ocean’s water never stops moving, and is known as a ‘global ocean conveyor belt’. Water takes approximately 1,000 years to travel around the globe.
If octopuses feel stress, they are known to sometimes consume their own tentacles. That’s right. Eat. Their. Arms. It’s called autophagy.
We are the minority
Approximately 94% of all life on earth is actually aquatic. Yep. That means us land dwelling humanoids make up just a tiny minority.
The size of oceans change
The actual size of the Pacific ocean is getting smaller, while the Atlantic ocean is getting bigger. Why? As North America’s plate moves further from Europe, the size of the oceans change.
The Mid-Oceanic Ridge is the longest chain of mountains on Earth, clocking in at 56,327 kilometres. It also happens to be underwater and makes up 23% of the Earth’s surface.
So much life in the ocean can’t be seen by the naked eye. There are approximately 1 million bacteria and 10 million viruses in just one millilitre of seawater. (It’s mostly harmless though!)
The pressure of water at certain depths could easily crush the Titanic like a can of Coke. But crabs, tubeworms and octopuses can live there happily. Pretty cool!
There are underwater waterfalls and lakes (some upside down!) in the ocean. David Gallo explains and shows these ‘underwater astonishments’ in a great Ted Talk.
Scientists speculate that approximately a million marine species are yet to be found – that means for every species we know, there are 3 we don’t!
