A question about water?

Question

water always fascinated me... because I always thought that the water we have today is the same water that existed 100 years ago, 1000 years ago, 7000000 years ago... I always thought that my blood consists of water that was in the veins of billions of other people in the past... water that was inside the dinosaurs, in the oceans, etc...

is this true? is water constantly recycled? or is old water destroyed and new water constantly created?

Answer 1

Water is chemically defined as H2O (small subscript "2"). The water molecule is composed of two hydrogen atoms attached to one oxygen atom.

I don't recall when the molecular composition last changed...

Answer 2

Ewwwww... I never thought about it like that. I would think its the same water somehow.  

Answer 3

Technically, yes.

Water is constantly 'recycled'.

Imagine: water that you drink into your system gets passed out via urine. This urine will go thru pipes before going to be recycled (it is done in some countries like Singapore) this water becomes our drinking water. In which, some of this water would evaporate to form clouds.

Clouds as we all know would fall as rain, which eventually gets absorbed by plants. When plants respire/transpire, they give out water and thus, the cycle continues..

yea

so technically, water is being recycled.

hope this helps!(:

Answer 4

Todays rain is the same water that has fallen for billions of years.

Answer 5

the water cycle never ends, it keeps on going an going so yes u probably do drink water that has at one time been inside dinasaurs  

Answer 6

It is absolutely true that water is constantly recycled. Or, more precisely, the hydrogen and oxygen atoms in our water have always existed since the Earth was formed. This is because no nuclear reactions with light atoms like H, O, N, etc. occur naturally on our planet.

For example, there's a good chance that, as we speak, you're breathing a molecule of air that was once breathed by a dinosaur.

Answer 7

You know what is also facinating? Tap water is actually pee from countless bladders, recycled by water companies to a "pure" form.

SO, to put it bluntly, the water we drink today and shower in used to be someone's pee.

Now you know the reason why Holiday Inn's water tastes like rotten eggs.

Answer 8

I think it it possible to create water in a lab out of its raw elements, hydrogen and oxygen, but most water is recycled naturally via the water cycle.

Answer 9

Yep, water is always recycled.

There are artificial ways to break up water on Earth, but no natural ways on Earth.

:D

Answer 10

Recycled, like almost every other piece of matter.

Some of the carbon in you could quite easily have been munching on brontosaurus at some point in the past ;)

Answer 11

It's the same molecules. It has been statistically proven you breathe in a molecule of Julius Caesar's last breath every time you breathe in.  

Answer 12

Mostly true but some water is broken down by and manufactured by natural processes.  Consider fossil fuels, the hydrogen content came from water and when burned creates new water.  Also some water arrives from space as from comets.  Sorry to burst your bubble but the decomposition and formation of water is a very small portion of the water on earth.

Answer 13

No, water is constantly re-used because it can't be made naturally anymore (unlike when the world began, a huge explosion of hydrogen and oxygen) so we just use and put it back into the earth.  

Answer 14

nah your right its just recycled, it goes up in the clouds and back down here. So you really could be showering in the water that jesus or king tut or someone used...techincally..

the only way that water could be lost in the earth, is like if it drips off a space ship engine or sumtin, but then again, it would still exist, it just wouldnt be in the world.  

Answer 15

That is actually a very very good point! I am guessing that some of it is new water though, not of that what they drank yyears and years and years ago but probably like 80 percent of it is.

Answer 16

it is true that water is constantly recycled!! think about it!! evaporated... rain!!!

evaporated again.... rain again

.....

Answer 17

Water never leaves the earth, its factually impossible. Water we drink, bathe and swim in, its all recycled. We drink, bathe and swim in the same water oas our ancestors. Its been proven.

Answer 18

Of course it's recycled. It may sound silly if you think it simple but where would those molecules go? Some of them turn into oxygen and hydrogen but at some point H will burn back to water.

Answer 19

Some water enters into compounds (remember putting lithium in water at school?). Some is released. But a lot of it stays around as water, so yes, you have some of Mohammed's p1ss in your bloodstream.
