Where did water come from originally?

Question

DaveToo · Accepted Answer

The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System in that it is the only planet known to have oceans of liquid water on its surface.[2] Liquid water, which is necessary for life as we know it, continues to exist on the surface of Earth because the planet is at a distance, known as the habitable zone, far enough from the Sun that it does not lose its water to the runaway greenhouse effect, but not so far that low temperatures cause all water on the planet to freeze.

It was long thought that Earth’s water did not originate from the planet’s region of the protoplanetary disk. Instead, it was hypothesized water and other volatiles must have been delivered to Earth from the outer Solar System later in its history. Recent research, however, indicates that hydrogen inside the Earth played a role in the formation of the ocean.[3] The two ideas are not mutually exclusive, as there is also evidence that water was delivered to Earth by impacts from icy planetesimals similar in composition to asteroids in the outer edges of the asteroid belt.[4]

One theory is most of it came from comet and asteroid impacts when the Earth was forming. Fun fact: The water you are drinking today has been around for around 4 billion years.

It was one of the first elements to form when the earth was created due to a planetary anomaly. It was the first place where life forms lived because before the ozone layer formed, it was too hot to be on land.

Did it come from Donald Trump's skull and ooze out of His ear as He was creating the Universe?  WWG1WGA

OlderAndWiser · Answer

The answer depends on your theory of how the universe came to be.

sensible27 · Answer

Part of water (oxygen) comes from supernova and the fiery cores of stars. The only elements (mostly) formed at the start of the universe were hydrogen, helium and a little bit of lithium (I think, 0.3% or so). Oxygen I'm assuming mixed (combined) at various places with hydrogen to form water (H2O).

If you're asking how did earth gets it's water, it's hypothised that in the early stages of the solar system, when it was forming and earth was new it was bombarded with a lot of asteroids that contained water.

NetSapien · Answer

There was once an Oxygen atom. This Oxygen atom would be pretty miserable and depressed because he was lonely. One day he comes across a very sexy Hydrogen atom and decides to go talk to her. They hit it off real well and were very happy. But after a year or so in the relationship, the Hydrogen atom decided it was time to spice up their love life and wanted to have a threesome. She convinced the Oxygen atom to invite in another Hydrogen atom to experiment. The Oxygen atom was excited at the prospect and agreed. Later that night, the Oxygen atom realized that the 2 Hydrogen atoms were getting a little moist and asked, what's that going on down there. The 2 Hydrogen atoms giggled and said "we got really wet"

and that's how water was born.

EssenceOfLight · Answer

Lots of water came with comets and asteroids. Most common material in earth crust are silicates and they contain oxygen. Under pressure and heat some of them transform in other materials and lose their oxygen atoms which bind occasionally with hydrogen and create water. Earth mantle and outer core contain several times more water than earth crust, oceans and atmosphere together.
Venus doesn't contain water on surface or atmosphere because water is bound into sulfuric acid and majority oxygen is bound as carbon dioxide. Mars doesn't have lot of water because mars atmosphere has a pressure below triple point of water. Water turns on Mars direct into vapor (gas). Mars has no magnet field, therefore most water evaporated into space due solar wind away from mars' gravity field. There are even hydrogen cloud photos which depict this occurrence around Mars.

ChiPaPa · Answer

At least on Earth, icy comets and asteroids from far out in the solar system bombarded Earth when it was a young planet. Some of that water attached into Earth and became part of it. Over the course of the life of the Sun, different atoms smashed together and created water.

Aquestion992 · Answer

The new research suggests that Earth's water came from both rocky material, such as asteroids, and from the vast cloud of dust and gas remaining after the sun's formation, called the solar nebula.

"There are those who believe that life here began out there, far across the universe, with tribes of humans who may have been the forefathers of the Egyptians, or the Toltecs, or the Mayans. Some believe that there may yet be brothers of man who even now fight to survive, somewhere beyond the heavens."

God made the world. He had to laugh so hard that tears were in his eyes. He used them as a spontaneous afterthought and - voila: there was water :)

exitseven · Answer

Since it is made up of oxygen and hydrogen and those two elements are abundant in out atmosphere there may have been some kind of event or catalyst that caused these two elements to form water.

dustybiker · Answer

I would guess it formed in the air first, then fell as rain with weight.

jshm2 · Answer

The same place pretty much everything on Earth did - outer space.

_no_one_ · Answer

In universe? must be some accidental collision of massive masses of hydrogen and oxygen atoms.  On earth? through comets if earth was barron before or through gaseous clouds from outer space.

Gwenhwyfar · Answer

I don’t know this without Googling it

Likes2drive · Answer

They say comets from billions years ago landing on the earth, even carbon life form but it is also from the mixing of oxygen and hydrogen while the planet was forming

Take an H, add a couple O's, and... voila... water!

Ad_Quid_Orator · Answer

When hydrogen chemically reacted with oxygen in the protoplanetary disk that formed our solar system.
