You’re likely aware that oceans occupy about 72% of the planet’s surface and contain 97% of all water. So what’s lurking underneath the surface? What mysteries do the depths hide? Why can’t we just dive deeper? These and other mysteries will now be unveiled!
Here are the top 9 unusual facts about oceans.
1. Underwater volcanoes
Up to 80% of all volcanic eruptions remain unnoticed by us up above. All because these eruptions take place underwater. According to researchers’ estimates, there are around one million volcanoes on the sea bottom. Some of them are dormant, and some are quite active, spewing molten hot lava directly into the ocean. Despite the high temperature, life can still be found near such volcanoes. Researchers believe these areas contain undiscovered species of sea creatures that are invulnerable to harsh conditions, including temperatures of over 400 degrees Celsius.
2. Fish eat plastic
More than seven billion tons of plastic are poured into the world’s oceans every year. Not surprisingly, plastic has become an undesired addition to the fish’s diet. Just in the North Pacific, fish are estimated to ingest between 12,000 and 24,000 tons of plastic each year.
3. Ocean’s blue tint
One of the most distinctive features of the ocean is its boundless blue surface. The color is the result of the sun’s rays (red and orange) being absorbed by the surface of the water while the blue light waves travel further. This cool dispersion effect makes the ocean water appear increasingly blue as you dive deeper.
