Where Does Water Come From?

Where did all the water in the world come from.If itsH2O where did all the gas come from?

  • if you burn hydrogen in air you get water this I know. If the density of water is several times that of air then we are talking a massive amount of hydrogen tied up in water so where did it all come from.

  • Answer:

    Each volcanic eruption has a small amount (sometimes as high as 5%) of water, either in liquid or vapor phase. In the early earth, volcanism was very active, and water was expelled for each eruption. Over time, water was expelled enough to be a significant portion of the surface. There is also some evidence for icy comets contributing to water, and this may play a part, but both must be factors.

Current scientific evidence points to comets as the source of earth's water; specifically, smaller chunks of ice that hit the earth. Older science texts attributed earth's water to volcanic activity.

The lighter elements, such as hydrogen, accumulated in our solar system from past supernova explosions. Most of this went into the sun, where it underwent fusion. From the sun, the heavier elements were expelled and accreated in orbit to form the planets (notice the rocky, solid planets, are closest to the sun). The earth's atmosphere used to be thin and extremely hot. The reaction occurred freely in these conditions, and hydrogen in the air was readily available.

space stuff. it's the water cycle you get water in the air and in liquid form all the time.

Just outside of Cincinatti. At least that's what I heard. :D

After the big bang settled into molecules, the only abundant element in the universe was hydrogen. It is still mostly hydrogen. Heavier elements were formed by the first round of supernovas, a hundred million years or so into the universe's existence.

The most abundant substance in this universe is hydrogen. It's found in stars, gas clouds, etc.

Some say it's a coincidence which i think is a very narrow minded answer, and it's not logic and i do not respect such people, nor such answers. As for me, I went into many researches and i keep going deeper and deeper, until I reach a point where you can find no answer, Example: How on earth does the human cell, suddenly start dividing its self creating more & more cells out of no where? what makes some cells create the heart some the brain some other organs? and they're designing a perfect human at the end? No one knows the answer, even scientists themselves, and guess what? it was meant to be that way so that you could believe in the existance of Allah, the creator of the universe, He All-Mighty did not only creat a perfect Universe, but even the tiny little cell in your own body. So answering your question, it all came out of no where, it is Allah that creates and doesn't be created, Allah The Most Powerfull.
