The Ocean is a very large expanse of sea, in particular each of the main areas into which the sea is divided geographically. The climate crisis has given us all a renewed appreciation for our planet’s oceans and the marine life that lives beneath the water’s surface.
Here are 5 mind-blowing facts about the ocean you probably didn’t know about,
- Our oceans cover more than 70 per cent of the Earth’s surface.
With so much of the Earth’s surface taken up by ocean, it’s evident how vital these marine environments are to the planet, and how much there still is to be explored.
- The majority of life on Earth is aquatic.
As so much of the Earth’s surface is underwater, it comes as no surprise that marine species outnumber those on land. But, it’s an incredible 94 per cent of the Earth’s living species that exist within the oceans.
- The world’s longest mountain chain is underwater.
Earth’s longest chain of mountains, the Mid-Ocean Ridge, is almost entirely beneath the ocean, stretching across a distance of 65,000 kilometres. It’s said that this mountain chain is less explored than the surface of Venus or Mars.
- Less than five per cent of the planet’s oceans have been explored.
According to the Ocean Service, man has explored less than five per cent of Earth’s oceans. As researchers strive to discover more, we’re continually getting to know our oceans better.
- There are more historic artefacts under the sea than in all of the world’s museums.
Around 1,000 shipwrecks lie off the Florida Keys alone, some of which are within the Florida Keys National Marine Sanctuary. Other underwater museums have been created in recent years, including the Mediterranean’s submerged bronze statue, Christ of the Abyss.
There are several other amazing facts about the deep blue sea which makes it nearly impossible for them to be fully listed.
