Around 70% of the Earth's surface is covered by oceans. The world's oceans contain enough water to fill a cube with edges over 1000 kilometres (621 miles) in length. Ocean tides are caused by the Earth rotating while the Moon and Sun's gravitational pull acts on ocean water.

Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.

The floor of the Pacific Ocean is divided into several plates. The largest one, the Pacific Plate is moving north west relative to the plate that holds North America, and relative to hot spots coming up through the mantle from below the plates (they generate islands like Hawaii).

(3) As the continental shelf does, islands would also have their own EEZ and patrimonial sea. ... There was even a proposal that islets and small islands--which were uninhabited and without economic life--would possess no continental shelf or other maritime space.
