Topics similar to or like ocean

Ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Wikipedia

Connected body of salty water that covers over 70 percent of the Earth's surface. It moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Wikipedia

Water in its liquid state that naturally occurs outside Earth. Subject of wide interest because it is recognized as one of the key prerequisites for life as we know it and thus surmised as essential for extraterrestrial life. Wikipedia

Type of terrestrial planet that contains a substantial amount of water as hydrosphere at its surface or within a subsurface ocean. Also used sometimes for astronomical bodies with an ocean composed of a different fluid or thalassogen, such as lava , ammonia (in a eutectic mixture with water, as is likely the case of Titan's inner ocean) or hydrocarbons like on Titan's surface (which could be the most abundant kind of exosea). Wikipedia

Most water in Earth's atmosphere and crust comes from the World Ocean's saline seawater, while fresh water accounts for nearly 1% of the total. Often referred to as the blue planet and the Pale Blue Dot. Wikipedia

Range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. The bounds of the CHZ are based on Earth's position in the Solar System and the amount of radiant energy it receives from the Sun. Wikipedia
