What could happend to the water cycle without the sun?

who needs the water cycle with out the sun. all living things would die without the sun.

i can tell u what would happen if we had no moon... this is the answer... \n\n\nIf the Moon did escape from Earth, the main effect would be the lack of tides on Earth. Tides are caused by the differential gravitational force on the equatorial regions: i.e. the region closer to the Moon experiences more gravitational force than the region on Earth away from the Moon. This results in the formation of high and low tides on different regions of the Earth. \n\nOther than tidal forces, there is no other geological or climatic influence of the Moon on Earth. There are issues like no more Moon to light up the night sky, no more solar eclipses, etc. but there will be no change in the geology or climate on Earth.

Yeah plants can grow without sun. those plants are called are non-photosynthetic plants. as they do not have photosynthetic pigments. They are also termed as chemosynthetic plants as they prepare their food by chemicals and not by sun light. As far as water is concrned then no plant on earth gorws without it. Water is essential for every livig animal. Its basic requirement for solutes and solvents to get transported from one cell to another. without it plants will DIe. try growing plants without water, they will shrink and eventually die.

The sun isn't expected to exhaust its nuclear energy for another 4-5 billion years, but when it does, it's supposed to turn into a white dwarf.  On Earth, pretty much everything would die after getting roasted, but that's a bit too far down the line to worry about.  There's a better timeline here: http://www-astronomy.mps.ohio-state.edu/~pogge/Lectures/vistas97.html\n\nPerpetual motion is pretty tough because there's always going to be some sort of friction, which causes heat and energy to be taken out of the system.  You then need to keep putting energy into the system for the motion to continue.

when the sun dies and runs out of fuel. Then the earth will die because of no photosysthesis.

Interesting question.  We would no longer have the moon's tidal forces, so no more high and low tides.  This would destroy the vast ecosystems along shorelines that depend on tides for their existence, and could well cause very negative effects on the Earth's entire balance of life, since these areas produce the most nutrients.

The sun causes the water to evaporate leaving the salt behind.

possible but its more on the no side, conditions not right for life, even for microorganisms that can take extreme temperatures and harsh environment...best of all...no water, its all ice caps!

Nothing. Even geothermal energy (heat from the center of the Earth) originally came from the Sun.

i would suspect that rainfall would decrease. the lower temperatures would result in less evaporation and the resultant precipitation. also, more water would become trapped in the ice caps. \n\nwe dont need to worry about this though as the trend suggests that things will get hotter rather than colder, despite the fact that we are in an ice age.

a) cyanobacteria \n\nOur atmosphere would have virtually no free oxygen nor any eukaryotes if not for them....

what is the water cycle??

Absolutely.  \n\nHow long depends on what you consider destroyed.   Chances are we'll be long gone before the planet is left abandoned by our own dieing sun which is about 1/2 way through it's life cycle.  From the linked Wikipedia artical, it claims that the earth won't be engulfed and vaporized by the sun, but it won't be a good thing one way or the other.\n\nWhat happens after we have no sun is tough to say, but you could probably argue that at that point if not long before the earth would be unable to support life.

if the water is at very very low pressure it can become gaseous.\n\nSee also - the triple point of water

There are two different "environmental conditions" which would affect the water: very low pressure and very low temperature.\nThe first thing to happen is that the water would "boil" (that is start to turn into a vapor).  This would be described as a "vacuum distillation."  This process (which removes heat from the liquid water), combined with the already low temperature would remove enough heat for the water to freeze.\nIf the container was allowed to remain exposed, the solid water would slowly continue to "sublime" (turn into a vapor under reduced pressure) until some sort of equilibrium was reached.\nNo.  I do not believe that this experiment has been tried, or if tried, the results released to the general public.

Life on earth will end before that.\nBecause sun before turning off will create havoc to earth's life supporting system.

You can observe this yourself by breathing on a mirror. As the condensation evaporates from the mirror, you have completed the water cycle. Water evaporates into the atmosphere from the ocean, lakes, rivers, and from soil and plants, and even from your skin and breath. When the air reaches saturation (100% humidity) due to cooling or changes in atmospheric pressure (or both) the water condenses from vapor to liquid (or solid) and falls to earth as rain, snow, sleet, hail, or maybe only as dew. This water may then form streams and rivers and return to the ocean where it may evaporate again into the atmosphere or it may sink into the earth where it becomes groundwater that may take many thousands of years to emerge again, or may be pumped to the surface from a well and used for drinking water or irrigation. It is a continuous cycle that may take only seconds or may take thousands of years to complete the cycle depending on the path of the water.
