====== Oceans ======

Terrestrial planets and moons in may have oceans, large (or multiple small) bodies of liquid that flow over the surface, evaporate and rain down again. Oceans come in three types, depending on the temperature of the orbit of the world. Besides these three, a [[Frozen Ocean]] exists to allow a [[Water Ocean]] on a planet in (:cold-orbit) cold orbit.

The orbit of the world determines the type of ocean. Worlds in (:hot-orbit) Hot orbits have oceans of magma and molten rocks and metals. They add a production bonus of +10 to zones that produce (:metals) metals. Worlds in (:goldilocks-orbit) Goldilocks orbits have oceans of water. Even without an atmosphere, (:organics) Organics may be produced on this planet as it is now [[Habitable]]. If the world also has an atmosphere (regardless of type), add a bonus of +10 to zone producing (:organics) Organics. Worlds in (:cold-orbit) Cold orbits have oceans of methane. They add a bonus of +10 production to zones that produce (:gasses) Gasses.

Oceans may cover the entire planet, large or small parts or may even be in the form of lakes, seas and rivers at the players choice. The exact details of this have no influence on the statistics. 

===== Types =====

^ ^ Ocean Type ^ Orbit Temperature ^ Advantages ^
| {{:rules:molten_rock_ocean.png?48x48|}} | [[Molten Rock Ocean]] | (:hot-orbit) | +10 (:metals) |
| {{:rules:water_ocean.png?48x48|}} | [[Water Ocean]] | (:goldilocks-orbit) | +10 (:organics) (with atmosphere)\\ Planet is [[Habitable]]\\ +5 Production (with [[Type II atmosphere]])\\ +10 Production (with [[Type I atmosphere]]) |
| {{:rules:liquid_methane_ocean.png?48x48|}} | [[Liquid Methane Ocean]] | (:cold-orbit) | +10 (:gasses) |
^  Special  ^^^^
| {{:rules:Frozen Oceans.png?48x48|}} | [[Frozen Ocean]] | (:cold-orbit) | The [[liquid methane ocean]] on the planet is a [[water ocean]] instead.\\ Planet gains free [[Natural Life]]. |

===== Cost =====

The cost of an ocean depends on the size of the world:

^ World Type ^ Biomass cost for oceans ^
| Small moon | 1 (:bio-mass) |
| Medium moon | 3 (:bio-mass)  |
| Large moon, small planet | 7 (:bio-mass)  |
| Medium planet | 19 (:bio-mass)  |
| Large planet | 37 (:bio-mass)  |

Note: The actual price is calculated per zone; the small moon entry displays the actual price per zone. This is relevant if you have other things that give you extra zones, such as the [[Underworld]] special.
