The ocean is a place home to milions of creatures. It is also the worlds largest body of water. Its seperated into five sections. The atlantic, pacific, indian and the southeren antarctic and artic oceans. Located to the east of the Mariana Islands in the western Pacific Ocean, the Mariana Trench is the deepest known area of Earth’s oceans. It's deepest point is around 11000 metres (36000 feet).

Around 70% of the earth's surface is covered by the ocean. The oceans tides are caused by the earth rotating while the moon and sun's gravitational pull acts on ocean water. The oceans waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules cause energy to be transferred from the wind to the water. This causes waves to form. A wave is defined as a transfer of energy.
