Ten Ocean Facts
By Riley Couillault
Fact One
Oceans cover more than two-thirds of the earths rocky surface. Their total area is about 362 million square kilometers, which means there is more than twice as much oceans as land!
Fact Two
In places, the pacific is so deep that the earths tallest mountain, Everest, world sink with out a trace.
Fact Three
Oceans can look blue, green or Grey. This is because of the way the light hits the surface. Water soak up the red parts of light but scatters the blue-green parts, making the sea look different shades of blue or green.
Fact Four
There are streams in the oceans. All the water in the ocean is constantly moving, but in some places it flows as currents, which take particular paths. One of these is the warm Gulf Stream, that travels around the edge of the Atlantic Ocean.
Fact Five
There are over 21,000 different types of fish in the sea.
Fact SixThe biggest animal on the plant lives in the oceans. It is a blue whale, measuring about 28 meters in length and weighing up to 190 tonnes.
Fact Seven
The top 200 meters of the ocean is called the light zone. At the continental shelf, sunlight can reach all the way to the seabed. However, within 10 meters of the waters surface, nearly all of the red parts of light have been absorbed, which means that many creatures appear dull in colour
Fact EightSix billion tonnes of phytoplankton grow in the light zone every year and they produce half of the oxygen on our atmosphere. Without them there would be almost no animal life in the oceans, one a few animals on land either
Fact nine
More than 4.8 million metric tons—that's about how much plastic waste gets dumped into the world's oceans from land each year.
Fact tenOcean tides are caused by the Earth rotating while the Moon and Sun’s gravitational pull acts on ocean water.
