Where did all the water on this planet come from ?

Question

Assuming that Earth started life as a very hot place where water could not exist where did all the water which now covers two thirds of the surface come from?

Answer 1

the bonding of hydrogen and oxygen

I guess that after the big bang the planet was a very hot place and a lot of hydrogen made up the atmosphere. When life on planet earth evolved so much that oxygen was released by organisms, the two elements combined to produce water. As life evolved more and more, the atmosphere changed and a cycle was set up between plants and trees releasing oxygen and taking in carbon dioxide and mammals taking in oxygen and releasing CO2

Answer 2

This is the real answer. I hope you believe it. This is true. In Genesis when God was creating the earth, the bible says that there was an expanse of water above the earth and below the earth. That means that there was water all around the earth which sealed in temperatures. The earth used to be one temperature all over.
Next reference. If you read from Genesis all the way to the part about Noah, you'll see that there was NO reference made to rain falling. As a matter of fact the whole account of Noah, in the beginning when God gave him the warning to build an ark because of the flood he will bring and cause rain to fall 40 days and nights, the people laughed, mocked him, since they had never seen rain, they thought he was mad. The rain that fell for that period was the water that was above the expanse of the earth. So now all that water is ON the earth.

Answer 3

Where to start? The earth started as a ball of dust which eventually came together to form the planet earth. Forget about water, think about the constituent atoms, Hydrogen and Oxygen.
Amongst everything else that is now found on the planet, these atoms were there in abundance. To cut a long story short, due to the atmospheric conditions and high level of volcanic activity on the primordial earth, water was formed from the constituent atoms of Oxygen and Hydrogen in vast quantities. Although there is no proof for it , it is suspected that at one time the whole earth was covered in water, some of which is now trapped below the crust and in the rocks that we see today.

Answer 4

The first source of water comes from beneath the ocean crust and catastrophic plate tectonics (a great Flood where collision of plates submerged one plate releasing water beneath to flood the earth).

Evidence that the Earth’s interior could participate in the process and that the stiff layer of rock some 50 miles thick beneath the oceans could be recycled into the Earth, set the stage for a breakthrough in regard to the mechanism for the Flood cataclysm. Laboratory experiments have carefully measured the way in which silicate minerals deform under conditions of high temperature and high stress. These experiments reveal silicate material can weaken dramatically, by factors of a billion or more, at mantle temperatures and for stress conditions that can exist in the mantles of planets the size of the Earth. The scenario in which all the Earth’s ocean lithosphere is rapidly recycled into the mantle via a runaway process, enabled by this stress-weakening behavior, is now known as catastrophic plate tectonics. The initial shape and extent of plates, including the distribution of continental crust, is specified as an initial condition. The initial plate configuration is an approximate reconstruction of Pangea derived from shapes of the present-day continents and data from the present-day ocean floor. In addition, an initial temperature perturbation within the earth's spherical shell domain is required to initiate plate motion. For this a temperature perturbation of -400 K to a depth of a few hundred kilometers is introduced around most of the perimeter of the supercontinent. Otherwise, the initial temperature within the interior of the shell is laterally uniform. Solving the equations of mass and energy conservation and force balance from this initial state yields a solution in which subduction of ocean plate occurs around most of the margin of the initial supercontinent and the continent blocks comprising this supercontinent are pulled apart. A reasonable inference is that this event corresponds to the Flood described in the Bible and other ancient sources along with compelling evidence in the geological record that such a cataclysmic episode indeed has occurred in the Earth’s recent past.

Answer 5

the earth is VERY old about 4.5 billion years. There are several time periods that the earth went trough. A example is Cambrian time the earth was covered with shallow warm seas, as the earth started to mature the shallow seas started to become land by evaporation etc....
Or you can go by the Bible: God made the earth also perfect for us and we need water to survive.

Answer 6

Water is a chemical combination of the two most abundant elements in nature, hydrogen and oxygen, both present in stars and interstellar matter. H2O exists in three states, gas (steam), solid (ice) and liquid (water) and undoubtedly is on Mars in lesser supply. There will be numerous other planets covered in the stuff. The real miracle is that at some point amino acids formed the ability to grow into more complex, developing, biological organisms.

Answer 7

God put it together, havn't studied enough to tell more, just that to put an expanse between the waters to separate water from water and put an expanse between the two. He called the expanse sky. I would assume the water in the sky would be clouds and this kinda thing

Answer 8

from asteroids that has crashed on the planet that contains frozen ice on it also from the bonding of hydrogen and oxygen and hydrogen is the most abundant atom in the universe .

Answer 9

the water on this planet did not come from anywhere, it was all ready here.and is constantly being recycled, we could be drinking the water that the dinosaurs excreted.

Answer 10

From the clouds above Manchester. It rains here enough to fill all the oceans in a week. freakin weather.:(
