| has gloss | eng: Underwater is a term describing the realm below the surface of water where the water exists in a natural feature (called a body of water) such as an ocean, sea, lake, pond, or river. Three quarters of the planet Earth is covered by water. A majority of the planet's solid surface is abyssal plain, at depths between 4000 and 5500 m (13,000 to 18,000 ft) below the surface of the oceans. The solid surface location on the planet closest to the center of the orb is the Challenger Deep, located in the Mariana Trench at a depth of 10,924 m (35,838 ft) under the sea. |

The bottom of the ocean is called the sea-bed. Most of the sea-bed is between 4000 and 5500 m (13,000 to 18,000 ft) below the surface of the ocean. Just like the Earths dry land, the sea-bed also has mountains, valleys and flat plains, although they are covered with water. The deepest part of all the worlds oceans is a place called the Challenger Deep, which is in the Mariana Trench. It is 10,924 m (35,838 ft) under the sea. |
