OUR AMAZING OCEANS

The longest mountain range in the world, the Mid Oceanic Ridge, is under water. This chain of mountains runs through the middle of the Atlantic Ocean and into the Indian and Pacific oceans. It is more than 35,000 miles long, has peaks higher than those in the Alps and it makes up 23 percent of the Earth’s total surface! (see picture in background- arrow points to Mid Oceanic Ridge)

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.

Why are so many people interested in the oceans? Maybe because of their size. The oceans on Earth are massive. Gigantuan. Huge. So is the information you can find about them, so here you will find...in no particular order....ten truly fascinating facts about the oceans of the world.

For starters, did you know that 94 percent of life on Earth is aquatic? That makes us land-dwellers a very small minority.

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!

About 70 percent of the planet is ocean. On average, it is 12,400 feet deep. Since light can’t penetrate more than 330 feet below the water’s surface, most of our planet is in a constant state of darkness!

In the ocean, there are underwater hot springs that shoot water that’s 650 degrees Fahrenheit! Inside these hot springs there is actually animal life! From 10-foot tall tubeworms to giant clams that function without digestive systems...animals can survive almost anywhere!

We didn’t send divers down to explore the Mid-Ocean Ridge until 1973 — four years after Neil Armstrong and Buzz Aldrin walked on the moon — when a French-American crew of seven entered the 9,000-foot-deep Great Rift in the French submarine named Archimede.

The ocean is home to many 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.Click the video below to see a marine biologist filming a sulfuric volcano underwater!

Many of the rules that apply on land are turned upside down in the ocean, some literally. Beneath the surface, often not far from popular vacation beaches, are underwater lakes, waterfalls and even upside-down lakes! *You can see these in a video on the last page of our Inquiry Unit!
