It has the same amount of water as 1000 years ago. Unless this water has been taken off the earth in a spaceship, it will always be on earth, some of it in gaseous for, some in ice, and some in water. Most of the earth's water is non-potable (meaning you can't drink it its not clean). Water is always recycled, for instance, the water you drink today, could also have been drunk by a dinosoar, then peed out. The water would be recycled over time, with all the bad things coming out when it evaporates, then it rains back to the earth as pure clean water.
The correct answer is no there is actually more water on the earth now then there was when the earth was formed because comets are made out of ice and when they enter the earths atmosphere they melt and create more water for the earth to contain
A lot less! Although one may think there is the same amount, referencing the law of conservation, water is a just compound of 2 Hydrogen atoms and one Oxygen atoms Being compound, it can be broken into its substituents during a chemical reaction, releasing this bond and causing the water to no longer be "water".
Due to industrialization and global climate change, a lot more water molecules are suspended in the atmosphere (evaporation) and are more freely capable of creating and destroying their current bond status (less "water") due to surrounding reactants in the air.
Same because the water has never left the earth it has always been on this planet so it is the same.
The amount of water on the Earth is more or less constant over recent geologic time, certainly the last 1000 million years.
The ice and water that are here today, is the ice and water that were here ten thousand years ago. It rolls through the hydrological cycle, nonstop.
Same
What is the answer
Earth does not produce water. The water currently on Earth is believed to have been here since shortly after Earth formed. Water on Earth goes through cycles between the atmosphere, the oceans, and glaciers.. Some water vapor is released by volcanoes, but this is balanced by water carried into the mantle at subduction zones.
The water amount is the same today as it has been for more then a million years. The Earth has the same water as it has had forever. You are drinking the same water that Hannah Montana or Jessica Simson drank yeaster day. I hope this answers your Q. so the answer is TRUELove,Lolishios
For the most part, the amount of water on Earth stays the same. The only way for the amount of Earth's water to increase would be for it to come from outer space. Not coincidentally, this is precisely what happens. Comets, made of dust and ice, enter the Earth's atmosphere and melt from the friction of the air as it plummets towards Earth's surface. The resulting water is then added to the already existing water in the earth's atmosphere (clouds), in bodies of water (oceans, lakes, etc.), and the water trapped in the form of ice (glaciers, icebergs, etc.)
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
The volume of water in the world generally remains about the same, but it is not a fixed quantity. Bear in mind that various types of meteoric material reaches the Earth from space all the time, some of which contains water. If the world is ever hit by a comet (which is entirely possible) there will be quite a lot of water added to the world's supply. There are several other factors which can alter the total volume of water in the world. Ordinary combustion produces a certain amount of water vapor as a byproduct. And photosyntheis consumes water.
According to most scientists, we have had virtually the same amount of water on Earth since the planet formed. That would mean that there was the same amount of water on Earth when the dinosaurs existed. However, it is important to note that there is probably an infinitesimal amount more water now then there was in the time of the dinosaurs, simply because of the fact that there have been meteors/meteorites that carried a little bit of water to Earth since the dinosaurs died out.
Yes - the Earth has a finite amount of water on it. This water cycles between the oceans and the atmosphere.
No, the amount of water stays the same on Earth. :-/

Simply by coincidence Earth and Venus accumulated close to the same amount of material when they formed.
The amount of water on earth does not change. Some of it may become ice, or melt into water, but the global amount is always the same.
The amount of crust present on Earth always stays the same. The amount of crust descending into the mantle is balanced by the amount of crust formed at mid-ocean ridges.
If you mean liquid water, then the Earth is the only planet. Mars has water ice in abundance but if melted, would probably not be anywhere near as plentiful as Earth. NASA calculates that if all the water ice was melted, Mars could be covered by water to a depth of 11m. So, as of 2010, no known planets have the same amount of water as Earth.
nothing is constant in the earth.everything changes every second in the earth.
During global warming all of the water was frozen leading to not much water now that it got warmer (green house affect ) there is more water now than then written by a fifth grader
No, the same amount of water is always available on earth. A lake may lose water, but that water has evaporated and will precipitate later on, perhaps in a different place.
There are exactly the same amount of water droplets on planet earth as there was when the dinosaurs roamed the planet. The hydrological perpetuation of the water cycle has just as many droplets as it did when the earth was formed by God. In theory, no water has ever escaped the confines of the planet except for the jettison of water in to outer space by the astronauts by accident or by design. Water evaporates, condenses as it cools and returns to the earth via the hydro cycle. hope this gives you the answer you were looking for
