yes all water is recycled via the water cycle first evaporated from the sea and joins to form water vapour(clouds), then it condenses as raindroplets falls onto mountains a drains off into the sea via river and lakes then the process starts again
In theory, the water that is present on our planet today is the same water that has been here for hundreds of millions of years. It continues to be recycled through the environment over and over in a constant cycle of evaporation and condensation known as the Water Cycle. Therefore, it is quite possible that you are drinking water that was once drank by dinosaurs.
this could very well be the case. Water does indeed cycle globally, and for the most part the same water is passing through the trophic levels, and being evaporated and rained down.
However, organisms do break apart and/or form their own water molecules inside their cells, including us. During cellular respiration (oxidative phosphorylation) sugars are broken down and used with the help of oxygen to make chemical energy molecules (adenosine triphosphate), and H2O is formed as a by product. this is how our cells make energy. This is how the cells of most animals and plants work.
Plants also break apart water molecules during photosynthesis, and use the hydrogen and oxygen atoms, in addition to the carbon and oxygen from CO2, and produce carbohydrates. Oxygen gas is a byproduct of this reaction.
these reactions are in effect opposites.
When water boils, in addition to water vapor, some oxygen gas is liberated as water molecules are busted apart(destroyed) from the kinetic energy that is heat.
therefore, the answer is possibly, as water molecules are created and destroyed virtually every living organism on earth.
yes, as the water they drank, they peed out, then that evaporated into clouds, then it rained, then it was in the oceans, then in the rivers and now, 250 million years later, it's in your evian bottle :)
Yes, we do use the same water as dinosaurs did thousands of years ago. This is possible because water is recycled. For all we know, we may be drinking water that was exhaled by the dinosaurs.
There is a possibility that that is possible because the water cycle has been going on forever.
yes we do because of recycling

The water cycle
There were no cities millions of years ago.
yes it did
Although almost all of the water on Earth today has been on the surface for millions of years, some is constantly added from underground rock, and a tiny amount by meteors. Some water is lost to the formation of minerals and compounds, and by the photodissociation of water (after which the some of the free hydrogen nuclei can escape into space).
rain started as soon as water came to earth,because there is water there is the water cycle, evaporation,condensation and precipitation.In fact the water we all have today is the same water millions and billions of years ago because of the water cycle.
Yes - they have barely changed from their prehistoric ancestors.
false because the earth contients was together now it is spreaded?
No! It's logical to conclude that small traces of water may have entered the earth's atmosphere through debris coming from space but on a question whether we've been using the same water in circulation since millions of years ago,Definitely yes!
Given that matter can neither be created nor destroyed, it follows that there are the same number of iron atoms now as there ever were.
there is still the same amount of water on earth as their was 100 years ago or in fact 1 million years ago. The fact is that today less water is in ice form then there was 100 years ago.
Carbon is a building block of all life and is an element that naturally occurs on this planet. There is the same volume of carbon on the planet today as their was millions of years ago.
the atoms have a cycyle
