10 Things You Didn’t Know About Our Oceans:
1. THE SUN GIVES IT THAT BLUE TINT.
2. THEY’RE KEEPING THE INTERNET ONLINE. Cables cross cross the oceans like a giant web.
3. THE DEEPEST PART IS REALLY, REALLY DEEP.
The Mariana Trench is considered to be the deepest part of the world’s oceans. Inside of the Trench is a valley known as Challenger Deep that extends roughly seven miles (36,070 feet) below the surface.
4. SOUNDS CAN TRAVEL TO THE DEEPEST EXPLORED AREAS.
5. LAKES AND RIVERS LIE BENEATH THE SURFACE.
6. THERE ARE 20 MILLION TONS OF UNTOUCHABLE GOLD IN THE OCEANS. It’s so diluted that it’s measured in parts per trillion. One liter of seawater might net you a 13-billionth of a gram.
8. THE BIGGEST WATERFALL ON EARTH IS IN THE ATLANTIC.
Putting Niagara Falls to shame is the Denmark Strait, a waterfall below the Atlantic Ocean that, in terms of water volume, is the equivalent of 2000 of the world’s most notable waterfalls, with cascading liquid pouring 11,500 feet down. The Strait’s cold water on the eastern side is more dense than the warm fluid coming from the west. When the two waters mix, the colder supply sinks, creating a waterfall.
9. WE DON’T KNOW ANYTHING ABOUT MOST OF THE MARINE LIFE We’ve identified only one-third of the potential marine life lurking beneath the surface. We’re making progress, though: An average of 2000 new species are described each year.
10. MAGELLAN NAMED THE PACIFIC OCEAN. He dubbed it the Pacific, or peaceful, ocean due to the calm surface.
