Hydrosphere (Greek hydro- means "water") in physical geography, describes the collective mass of water found on, under, and over the surface of a planet. On Earth, the water cycle describes the methods of transport for water in the hydrosphere. This cycle includes water beneath the Earth's surface and in rocks (lithosphere), the water in plants and animals (biosphere), the water covering the surface of the planet in liquid and solid forms, and the water in the atmosphere in the form of water vapor, clouds, and precipitation..

It's the most important part of our earth. Just like our body.. 70% portion of water is in our body.

Water! Most of the earth is covered with water.

water, drinkable water. territorial access to ports and water. \n\none day certain water may get so contiminated the ecosystem will not be able to purify the water. then ground water will become very valuable.

97% of the worlds water is salt water, 2% would be fresh water locking in glaciers and ice caps, and the remaining 1% would be stored in aquifiers, groundwater, lakes, rivers, ponds, streams. so to answer the question, ponds represent<1% of the worlds water supply

True. water is essential for the transport of nutrients within them, since it is the "universal solvent".

mainly to do with temperature and climate in various parts of the world be unable to sustain a  natural water supply

water as in H2O? just ok...\nyeah covered with it... \nas long as the planet is not made up entirely of water.... that wold be like a big floating water vapor....\nhaha

There is no way for this to be possible b/c water is in EVERYTHING you eat & drink. So if you include all water on the planet then you include the water in drinks & food as well as in other places you forget like the atmosphere, your body, etc. Water water everywhere! :)

Look up "hydrologic cycle":\n\n1. evaporation / sublimation / transpiration\n2. atmospheric storage \n3. condensation / precipitation\n4. runoff / infiltration

bottled water...water is the source of sustaining life..nothing can survive without water on earth..

Yes it is. The water is constantly recycled, between lakes, groundwater, rivers, seas, ice caps/galciers, clouds, used by humans etc. (Not in this order though)\n\nThe only time that there is any 'new' water introduced is when a volcano erupts.

Tap water.\nSoap breaks down the surface tension.

To sustain life(fauna/flora) on earth especially inland area.\nWater Cycle:\nOcean evaporate > vapour rise to sky > condense form cloud >\nmeet cold front become rain > rain form stream >stream form river > river flow to coast.\nwhen the cycle is disrupt or changed, drought/flood occurs.\nthe site below is an US site for:

Though 78% of the earth are water bodies, as per a study 88% of the water available in the world is from seas and oceans and not potable. Desalination in some areas are done at a very high cost which is only 0.007%, so it is very negligible. Of the balance 12% or less 50 percent of all potable water is wasted or lost in the developing world; Pollution, with some 2 million tons of human excrement and an ever-increasing volume of untreated discharge from industry going into urban water supplies every day. The ground water table is also depleting very fast and getting contaminated or many areas have become dry. This accounts for +3%. The balance of 3 % are so is available now.\n\nIn the developing world, more than 1 billion people cannot get clean drinking water, and 1.7 billion people lack access to adequate sanitation facilities. The United Nations says that dirty water causes 80 percent of diseases in the developing world, and kills 10 million people annually.\n\nWATER CRISIS IS LIKELY TO STRIKE MOST DEVELOPING WORLD CITIES BY 2010. \n\nThus the position is very alarming and water conservation and Storm water harvesting are being implemented by many countries to save the situation.

Water, you can not sustain life without it. That includes every form of life, man, animal, forests, bacteria, etc. Everything!\n\nAir, which contains oxygen on which we as human beings depend on for our dear life.\n\nSunlight, which is the beginning of our very existence. Imagine what life would be if there was no sun. \n\nThere are many other natural resources which surround us on this wonderful planet called the Earth. But I would say that these three definitely top the list.\n\nBy the way, you ask very intelligent questions. Good for you to be so concerned about your enviornment.
