Where does water come from?

Question

i have no idea can you help me out?

Answer 1

water is trapped in ice caps, glaciers, aquifers, or in lakes, sometimes providing fresh water for life on land.

Water moves continually through a cycle of evaporation or transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Winds carry water vapor over land at the same rate as runoff into the sea, about 36 Tt per year. Over land, evaporation and transpiration contribute another 71 Tt per year to the precipitation of 107 Tt per year over land

Answer 2

Well its two hydrogen atom and one oxygen atom.

It comes from mountains into rivers, then into the sea, then evapourates, into clouds, which rains, back on the maintains.

And it comes from the tap.

Answer 3

underground...

Answer 4

Water came from chemical reactions when the earth first cooled down from a valcono like planet. Water is constanly being re-used from the water cycle, so the water we drink is like 6 billion years old.

Answer 5

clouds  

Answer 6

The same amount of water has been with us on Earth since the Earth was formed.

It's called the 'Water Cycle' or 'Hydrological' cycle.

The Ice caps may melt, the seas may freeze, Clouds (water vapour) may Increase or Decrease, different areas of the Earth may suffer Drought, or Floods, Lakes and rivers may dry up in some places and overfill in others but, overall, the amount of water remains the same and the above conditions will constantly be changing.

Water has nowhere to go and nowhere to come from...it's always with us in the same total quantity.

This is not from a web-site. However, Mr. Thumbs downer, look up the 'Hydrological Cycle', you'll find it's correct.

Answer 7

Water comes from the Ocean, Rivers, Lakes etc...

It does not come from space or the sky....The Water cycle...so you always drink the same water...take a look at the picture

Answer 9

The chemical reaction between hydrogen gas and oxygen gas.

Answer 10

Asteroids crashed onto the earth billions of years ago, and they were very cold and practically 'ice'

these eventually melted with the earths atmoshpere being warmer than 0degree's

and there the seas were created,

then it evaporates, rains in the mountains mainly and is collected because it is more pure because of the minerals in rocks.

Answer 11

Water is made of two gases: Hydrogen and Oxygen.  Two hydrogen atoms combine with one oxygen atom to make one molecule of water. The chemical formula for this is H20 (the 2 is a little subscript one).

We made water at school by putting hydrogen and oxygen into a big plastic container, then attached a small detonator to the s***w cap, took it out onto the school field and detonated it.  We got water, but most of it was uncollectable, owing to the explosion.  I don't think they'd allow it these days.

Answer 12

the sky?

Answer 13

The tap.

Answer 14

Your city's pipelines! jk! People say it comes from plants, after it goes through the carbon, oxygen cycle, hope that helps!

Answer 15

Much of water in the Universe is a byproduct of formation of stars. When stars are born, their birth is accompanied by a strong outward wind of gas and dust. When this outflow of material eventually impacts the surrounding gas, the shock waves that are created compress and heat the gas. The water observed is quickly produced in this warm dense gas.

Answer 16

Most scientists suspect that Earth's supply of water came (not from asteroids) but from icy comets crashing into the early Earth.  In the earliest part of the of life of our solar system, comets where thought to be much more common than they are now.  After 4.5 billion years, the few that are remaining are are either still in the Oort cloud or are in somewhat stable orbits.

========= Follow up =========

Asteroids are rocky material that don't contain much in the way of water ice.  I also noticed that someone said that water came from the volcanos.  There is a lot of steam produced during volcanic eruption, but it is only the water that is already here.  Volcanos don't "create" water.  Also, that same person said the Earth is six billion years old.  The best estimates of the Earth's age put it between 4.5 and 4.6 billion years.

Answer 19

first take a look at this pic it'll help you realize that water does not actually "come" from anywhere
