Ὠκεανός,
(okeanós)
(the ‘sea’ of ‘classical antiquity’)
.
*an “ocean” is a body of ‘saline water’ that composes much of a planet’s ‘hydro-sphere’*
.
(on ‘earth’, an ‘ocean’ is one of the major conventional divisions of the ‘world ocean’, which covers almost 71% of its surface)
(the word sea is often used interchangeably with “ocean” in ‘american english’ but, strictly speaking, a ‘sea’ is a body of ‘saline water’ (generally a division of the ‘world ocean’) ‘partly’ or ‘fully’ enclosed by ‘land’)
(‘saline water’ covers approximately 72% of the planet’s surface (~3.6×108 km2) and is customarily divided into several ‘principal oceans’ and smaller ‘seas’, with the ‘ocean’ covering approximately 71% of earth’s ‘surface’ and 90% of the earth’s ‘biosphere’)
(the ‘ocean’ contains 97% of earth’s water, and ‘oceanographers’ have stated that less than 5% of the ‘world ocean’ has been explored)
(the ‘total volume’ is approximately ‘1.35 billion cubic kilometers’ (or ‘320 million cubic miles’) with an average depth of nearly ‘3,700 meters’ (or 12,100 feet))
(as it is the principal component of earth’s ‘hydrosphere’, the ‘world ocean’ is integral to all known ‘life’, forms part of the ‘carbon cycle’, and influences ‘climate’ and ‘weather’ patterns)
(it is the habitat of ‘230,000 known species’, although much of the oceans depths remain ‘unexplored’, and over ‘2 million marine species’ are estimated to exist)
(the origin of earth’s oceans remains unknown; ‘oceans’ are thought to have formed in the ‘hadean period’ and may have been the impetus for the emergence of ‘life’)
(‘extraterrestrial oceans’ may be composed of ‘water’ or other ‘elements’ and ‘compounds’)
(the only confirmed large ‘stable bodies’ of ‘extraterrestrial surface liquids’ are the lakes of ‘titan’, although there is evidence for the existence of ‘oceans’ elsewhere in the ‘solar system’)
(early in their ‘geologic histories’, ‘mars’ and ‘venus’ are theorized to have had large ‘water oceans’)
(the ‘mars ocean hypothesis’ suggests that nearly 1/3 of the surface of ‘mars’ was once covered by ‘water’, and a ‘runaway greenhouse effect’ may have boiled away the global ocean of ‘venus’)
(compounds such as ‘salts’ and ‘ammonia’ dissolved in ‘water’ lower its ‘freezing point’, so that ‘water’ might exist in large quantities in extraterrestrial environments as ‘brine’ or ‘convecting ice’)
(unconfirmed oceans are speculated beneath the surface of many ‘dwarf planets’ and ‘natural satellites’; notably, the ocean of ‘europa’ is estimated to have over twice the water volume of ‘earth’)
(the solar system’s ‘giant planets’ are also thought to have ‘liquid atmospheric layers’ of ‘yet-to-be-confirmed compositions’)
(‘oceans’ may also exist on ‘exoplanets’ and ‘exomoons’, including surface oceans of liquid water within a ‘circumstellar habitable zone’)
.
(‘ocean planets’ are a hypothetical type of ‘planet’ with a ‘surface’ completely covered with ‘liquid’)
