A little ocean trivia for you
Watching National Geographic introduced me to a few little known tidbits about the ocean.
For example, did you know that 70% of the world’s volcanoes are in fact not seen? They sit below the ocean’s surface. 90% of all volcanic activity on Earth occurs in the ocean.
Nearly 400 people in total have been sent to space. Do you know how many people have been to the deepest known part of the ocean floor? Only 2. In 1960, two divers in the pressure-resistant, one-atmosphere bathyscaphe “Trieste” made the ultimate voyage to the bottom of the deepest part of the ocean, touching the sea floor nearly seven miles below the surface. Nobody else has done it since.
Almost all of the deep ocean temperatures are only a little warmer than freezing (39°F)!
At the deepest point in the ocean, the pressure is more than 8 tons per square inch or the equivalent of one person trying to hold 50 jumbo jets.
Why is the ocean blue? The ocean looks blue because sea water absorbs all of the reds, yellows and greens out of the water, leaving only blue light to be reflected by the water molecules.
