==Description==

==Description==

A '''lake''' (from [[Latin]] lacus) is a terrain feature (or [[physical]] feature), a [[body]] of liquid  on the [[surface]] of a world that is localized to the bottom of basin (another type of landform or terrain feature; that is, it is not global). Another definition is a [[body]] of fresh or salt [[water]] of considerable size that is surrounded by land. On [[Earth]] a body of [[water]] is [[considered]] a lake when it is inland, not part of the [[ocean]], is larger and deeper than a pond.  The only world other than [[Earth]] known to harbor lakes is [http://en.wikipedia.org/wiki/Titan_(moon) Titan], [http://en.wikipedia.org/wiki/Saturn Saturn]'s largest [[moon]], which has lakes of [http://en.wikipedia.org/wiki/Ethane ethane], most likely mixed with [http://en.wikipedia.org/wiki/Methane methane]. It is not known if Titan's lakes are fed by [[rivers]]; Titan's [[surface]] is carved by numerous river beds. There is [[evidence]] that [http://en.wikipedia.org/wiki/Mars Mars] once held lakes of [[water]].

[[Natural]] lakes on [[Earth]] are generally found in mountainous areas, rift zones, and areas with ongoing or recent [http://en.wikipedia.org/wiki/Glacier glaciation]. Other lakes are found in endorheic basins or along the [[course]]s of [[mature]] [[rivers]]. In some parts of the world there are many lakes because of chaotic drainage [[patterns]] left over from the last [http://en.wikipedia.org/wiki/Ice_Age Ice Age]. All lakes are [[temporary]] over [[geologic time scale]]s, as they will slowly fill in with sediments or spill out of the basin containing them.[http://en.wikipedia.org/wiki/Lake]
