how old is the water in the oceans?

Answer 1

How old are water masses?

Professor Peter Weyl, retired but previously at the State University of NY at Stony Brook, estimated that the Atlantic deep water is about 400 years old. Age will, however, depend upon when the water mass is left the source area at the sea surface.

Pacific ocean waters are older than the Atlantic; Deepwater in the Pacific can be 1500 years. Recall that as a result of thermohaline circulation a fraction of the North Atlantic Deep Water (NADW) eventually finds its way into the Pacific. This is "old" NADW in the Pacific is estimated to be 1500 years old by Professor Weyl.

Answer 2

Some is the same age as the Earth/solar system, some much older. A lot of the Earth's water condensed from the hydrogen and oxygen that existed in the primordial cloud that formed the sun and planets about 5 billion yrs ago. Some water already existed as ice that was drawn into the cloud by gravity as it formed and came from other stars/planets long since destroyed even further back. This older water fell as comets during the formation of the Earth. Some continue to fall to this day!

Answer 3

It is thought that water came from the comets that hit earth during the early years when there was no life. The water in the oceans is older than life on earth and like everything else that isn't hydrogen, was once part of a star. It seems that everything here on earth was once start stuff.

Answer 4

As long as when water was formed on earth. Water volume is almost a constant on earth it's forever in the water cycle. Climates will change and so will the presence of water in any area of the planet, but as a whole, the water volume is always the same.

Answer 5

Hi. The hydrogen in water was formed at the beginning of the universe. The oxygen was formed in a star much later. They could have combined anytime so if your question is how old are the ATOMS in water then two thirds are as old as the universe, or 13.5 or so billion years old.

Answer 6

4.6 billion years old. There were also ancient oceans that was the same water but different shape like around the time of Pangaea.

Answer 7

we are tying to find if theres water on Mars or any other planet or sattelite for that matter. As far as we are concerned, we for sure know that thats were the basics of life began.

Now how old do you think the water on earth is ?

:)

Answer 8

There is no way to tell. They say that all life crawled out of water. How are we supposed to know? This is a question that will always be unexplained...

Answer 9

It should be more than 300,000 million years as almost everything on Earth went extinct 300,000 million years ago and waster has been there before the dinosaurs.

Answer 10

itsw the same water the dinasors pooped in. there is no new water. it just keeps geting evopared then rained back down.
