How did water come to exits?

Question

Okay, I know about the big bang! a huge explosion. But how did planet earth end up with so much water. Water is very rare in the universe, in fact, we may be the only planet in our solar system with water, water has not been found in any other planets. There is absolutely no evidence of water anywhere else in the universe.

So where did all this water come from?

Im talking about water...liquid water not ice but water which is what even the hardiest known critters need to survive.

Why only here on earth?

Answer 1

How do you know there is no evidence of water any where else in the universe?Signs of water have been found on at least three planets other then Earth.Do some more research before suggesting that.Or do you think God urinated the seas into existence?

Answer 2

Two atoms of hydrogen combine naturally with one atom of oxygen = H20 = water.
Absolutely no evidence that there ISN'T water in many other locations in the universe. We have only explored a miniscule part of our own solar system. BTW, ice has been discovered on Mars.

Incorrect facts claimed - shows ignorance. You should read the right books more often. Didn't they teach you this in school? Hey - maybe you are still at school and haven't got that far yet. Maybe you are at a religious school? Major error of judgement if so.

Anyway, now you know. Do ignore ANY answers with the word god in it.

Answer 3

Volcanism, actually we are the only planet with a hydrosphere. That is water in the form of a LIQUID. The water came from early in the earths formation due to tremendous amount of volcanism. Tons of water is released during a volcanic eruption believe it or not. The water remains a liquid due to our distance from the sun. On mars its too cold for it stay as a liquid and on mercury is too hot. Earth turns out is just right.

Answer 4

if it came to the exits perhaps you should look for the entrances ? I'm not a physicist or chemist but I would hazard a guess that since it is made of such simple elements as hydrogen and oxygen that might acount for some of it but it
s probably much more complex as other planets don't have this abundance tha we are so fortunate to enjoy . good question though you should take it to the science venue were you should be more likely to get a better answer .it may have to do with temperature ?

Answer 5

It is because the gravity of the earth and the temperature (which result mainly from the distance earth-sun) are supporting the existence of liquid water on earth. And you are wrong when you say that water is very rare. There is water on Mars, though not as much as on earth (probably because Mars as a lower gravity and lost much water to space). Check www.nasa.gov. The elements hydrogen and oxygen are frequent in the universe, and on planets similar to ours they are very likely to combine to H2O, as on earth.

Answer 6

Actually water is extremely common in the universe. It is present in huge quantities on Mars, on Europa, on Enceladus, on Mimas, in comets, in interstellar space, possibly even in shaded craters on Mercury. The Kuiper Belt is composed of probably millions of objects which are mostly water, comprising billions of tons. Water is ubiquitous.

EDIT: Several satellites are thought to have vast sub-surface liquid water oceans, e.g. Europa, Enceladus, Mimas. In fact these ice-crust, liquid water bodies could well be common throughout the universe and therefore the greatest habitable environment in the universe.

Answer 7

Water comes from burning hydrogen in the resence of oxygen.

Hydrogen is extremely abundant in stars.

There's also emerging evidence of water flows on Mars, and on our moon, as well as the moons of some of the outlying planets, and of water ice in comets.

Answer 8

it's rare because the oxygen molecule is having an affair. SEE,

H-O-H that's water, well techniquely
H H
\ /
O

you see that slutty oxygen? It's bonded to 2 hydrogen molecules. And you need 2 hydrogens to NOT noticed each other while still bonded with the oxygen. That is why it's so rare. You need a lot of dumb hydrogens and slutty oxygens.

Answer 9

its a simple three atom molecule, made of hydrogen and oxygen, both very common elements

and believe it or not, there is plenty of water in other parts of the universe, take mars as an example

Answer 10

God created it as a way to sustain life but I am sure I have heard news they are sure there has been water on other planets and wonder if some is still there but frozzen underground.
