Ocean – the four to seven largest named bodies of water in the World Ocean, all of which have "Ocean" in the name (see: Borders of the oceans for details). Sea has several definitions: [a] A division of an ocean, delineated by landforms, [6] currents (e.g., Sargasso Sea), or specific latitude or longitude boundaries. This includes but is not ...
The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
The other "oceans" are found under thick covers of surface ice. If both liquid and frozen water are counted, Earth ranks fifth in volume of its oceans. [2] Recent studies indicate a large underground saltwater ocean present on Ganymede, Jupiter’s largest moon, with estimated water volume eight times greater than Earth’s world ocean. [3]
World map of the five-ocean model with approximate boundaries. This list of countries which border two or more oceans includes both sovereign states and dependencies, provided the same contiguous territory borders on more than one of the five named oceans, the Pacific, Atlantic, Indian, Southern, and Arctic.

The ocean is a major driver of Earth's water cycle. Ocean water represents the largest body of water within the global water cycle (oceans contain 97% of Earth's water). Evaporation from the ocean moves water into the atmosphere to later rain back down onto land and the ocean. [69] Oceans have a significant effect on the biosphere.
The Denmark Strait cataract is roughly 20 times the size of Niagara Falls and is the biggest waterfall on earth. Located miles underneath the Atlantic Ocean between Greenland and Iceland.
a part of a lake or ocean that extends so that it is surrounded by land on three sides, similar to, but larger than a bay. Harbor: an artificial or naturally occurring body of water where ships are stored or may shelter from the ocean's weather and currents. Hot spring: a spring produced by the emergence of geothermally heated groundwater ...
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on the definition, to Antarctica ) in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
