Less than 10% of the Earths oceans have been explored and over 50% of all living organism are in that 80-90% that we haven’t touched. The ocean makes up most of the earth and humans don’t even have the slightest idea of what all is in it. But what we do know is both terrifying and immensely intriguing so that is why I thought that I would make a list of facts about things you may or may not know about the earths ocean. 🙂

1. Currently, scientists have named and successfully classified over 1.5 million species. It is estimated that there are as little as 2 million to as many as 50 million more species that have not yet been found and/or have been incorrectly classified. (source)

2.About 70 percent of the planet is ocean, with an average depth of more than 12,400 feet. Given that photons (light) can’t penetrate more than 330 feet below the water’s surface, most of our planet is in a perpetual state of darkness.

3. Fifty percent of the United States (in terms of our complete legal jurisdiction, which includes ocean territory) lies below the ocean.

4. The deep sea is the largest museum on Earth: There are more artifacts and remnants of history in the ocean than in all of the world’s museums, combined.

5. We have only explored less than 5 percent of the Earth’s oceans. In fact, we have better maps of Mars than we do of the ocean floor (even the submerged half of the United States).

6. The longest mountain range in the world is under water. Called the Mid-Oceanic Ridge, this chain of mountains runs through the middle of the Atlantic Ocean and into the Indian and Pacific oceans. It runs more than 35,000 miles long, has peaks higher than those in the Alps and it comprises 23 percent of the Earth’s total surface.

7. The ocean boasts an array of unusual geographic features, such as pillars that reach several stories high and chimneys that send up sulphuric acid. In the ocean-floor neighborhood of the Gulf of Mexico, brine pools mark the floor, along with underwater volcanoes that spew mud and methane, rather than lava.

8.  These wonderful formations aren’t barren, either. Underwater hot springs that shoot water that’s 650 degrees Fahrenheit — hot enough to melt lead — boast a profusion of life, from 10-foot tall tubeworms to giant clams that function without digestive systems.

Here is where I found all facts from 2-8 🙂
Oh and here is this image I found When I was in 7th grade that I still haven’t forgotten about till this day.
I found this on Google Images under “depth of the ocean”. When I tried to visit the source it just kept taking me to another webpage that only looked to be like an advertisement because it had nothing to do with the ocean and more to do with condoms and the picture was no where in sight.
