Will the Earth run out of water like the Mars and the Moon did many eons ago like the scientist claim?

Answer 1

each day we lose water into the mantle. earth will eventually be dry like mars, but it won't be for quite some time.

Answer 2

Whether or not a planet/satellite loses fluids to space depends on the gravitational field of the body and the molecular weight of the particular gas. Thus Earth can't hold free hydrogen and helium because the average velocity of the molecules at ordinary temperature exceeds the escape velocity. Earth can hold water, methane, carbon dioxide, argon, nitrogen and oxygen as these are much heavier gases with far slower molecules at ordinary temperatures and it's only the very rare fastest ones that can exceed escape velocity. Like one molecule in several hundred thousand billion, or less. These losses are more than made up by bits and pieces falling into the atmosphere as meteors so there is probably a net gain.

The escape velocity of the Moon is much lower than that of Earth so any gases that form an atmosphere soon evaporate into space. Mars has a higher escape velocity than the Moon, but lower than that of Earth, but it is able to hold an atmosphere at it's ordinary temperature. Most of the gases on Mars, mainly CO2 and H2O seem to be frozen into the ground or frozen into the polar caps.

Scientists, stupid or not are unlikely to split water into hydrogen and oxygen in large amounts. However if some businessmen can make money doing so, goodbye seas!

Answer 3

Mars didn't lose its water: the water just turned into ice.
I don't think the moon had water... ever.

Earth is the only planet in the Solar System where water naturally occurs in three states of matter.
Anyway, the water will never run out unless some stupid scientists split all water into hydrogen and oxygen, or the Earth just blew up.
>The water would just transform, not disappear.

Answer 4

It depends. The water on earth is kept on the planet by the gravitational effect of the earth magnetic field. Mars lack of liquid water, it does have frozen water at both poles, is believed to be due to this, the gravitational magnetic field isn't strong enough to stop it floating off into space.

If we assume that the earth is going to have a constant gravitation effect and the water lost to space will be minimum then the water to be lost must have gone somewhere else. Water is one of the most stable compounds known and as such is the must likely form of compound found when hydrogen and oxygen mix.

Answer 5

No. The Moon did not run out, it never had water.Recent observations of Mars with ground penetrating radar show water ice at the poles several miles thick. Other observations show what appear to be frozen oceans covered by a thin layer of dust at several other places on the planet. And lastly, Earth is not loosing water. Statements you may have heard about us running out of water only mean formerly clean water is increasingly polluted and over used by a growing population, not water actually leaving Earth!

Answer 6

Well... Mars hasn't run out of water. :D There's evidance to suggest that there's still water that runs on the surface.

And the Moon never really had water, it was a bunch of rocky bodies that were drawn together to form one body.

As to your question, it's always possible. It all depends on other circumstances, but it's a good idea to conserve water and protect it anyway.

Answer 7

as long the earth has its magnetic shield it will constantly keep the balance of water loss "balanced" and the atmosphere thick enough, we loss some water because of solar wind but regain it by the thousands of small comets that rain form space every year, the number is quiet big you can check it out on discovery channel or NASA web site. so don't worry unless our shield fails like Mars then .... well Bummer :)

Answer 8

Not untill the sun decides to expand... I don't think that the moon had water on it. After all, it was created from interplanetary collision. How could it?

Answer 9

Probably not. If our water supply ever ran out it would take many milleniums for it to happen and we would most likely have a solution for it by then.

Answer 10

Plausable but unlikely considering we have our weather that produces rain. If push comes to shove we could always desalinate the ocean.
