The ocean is a massive force of nature, not to be taken for granted. While we appreciate the beauty of the oceans from land, there is still much to be learned about this massive body of water that engulfs our planet. Here are five interesting facts about the ocean you may not know.

 

  1. There’s More Life in the Ocean Than on Land

 

In fact, aquatic life comprises at least 94% of all life on the planet. Researchers estimate that aquatic life began around 3.5 million years ago. That’s allowed plenty of life forms to evolve, including the Great Barrier Reef, which is a living organism.

 

  1. 95% of the Oceans have Never Been Explored

 

Mars is better mapped than the world’s oceans. Why is this? Due to low resolution, the floor of the ocean can’t be measured in the same way as land. Who knows what could be lurking in the depths of the ocean? New aquatic species are discovered every year.

 

  1. There’s Really Only One Ocean

 

For convenience, humankind has given different regions of the bodies of water on earth unique names. The differences among each area of water include current, temperatures and aquatic life. Technically, though, it’s all just one big mass of water. What impacts a small area ultimately impacts the entire ocean and the life forms it contains.

 

  1. The Ocean Contains Gold

 

According to estimates, there are over 20 million tons of gold in the ocean. The concentration is only about one gram of gold to 100 million tons of ocean water, though. More solid gold may be found about a mile or so beneath the seabed, encased in rock. If you’re looking to get rich from gold digging, you’d best look elsewhere. Mining the ocean’s treasure trove of gold is likely not cost-effective.

 

  1. Earth’s Largest Mountain Range is Under Water

 

The Mid-Oceanic Ridge is an estimated 40,390 miles long, and it’s almost completely beneath the ocean. Only about 10% of this range is above water. The Mid-Oceanic Ridge is in the Atlantic Ocean, running almost straight down the center.

 

You’ll probably look at the ocean a lot differently the next time you’re at the seashore. These five amazing ocean facts are sure to astound you.
