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 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
