Before we dive into our discussion, there are some facts about the ocean we should learn first.
(1) The ocean contains 97% of the planet's water and it covers approximately 71% of the surface.
(2) Earth has five major oceans. The largest is The Pacific, located between the Southern Ocean, Asia, Australia and the western hemisphere, over an area about 15 times the size of the USA. It contains more than 25,000 islands.
(3) The largest ocean on Earth is the Pacific Ocean, which covers approximately one third of the Earth’s surface. It measures over 180,000,000 kilometres square and has a larger surface area than all of the continents of the Earth combined. It is also the deepest ocean, with an average depth of 4,280 metres, but at its deepest, measures an amazing 11,033 metres. The deepest point is called the Mariana Trench which is at the bottom of the Challenger Deep.
(4) On average the depth of the ocean is 12200 feet, or 2.5 miles or 4.5 kilometers.
(5) The oceans are the greatest habitats on the planet providing more than 99% of living space with more than 90% living in the deep sea or the abyss. This means that more than 90% of the wildlife on earth live in the oceans.
(6) The deeper you travel into the ocean the more the pressure that builds up. At the deepest part of the ocean, the pressure is 8 tons per square inch; too much for any human being to handle
