What is a Water Cycle?

Are you talking molecular level or physical process?\n\nWater is the bond between Hydrogen+ and two Oxygen- formulating H2O.\n\nWater as in the rain.  Evaporation is the water droplets from the sun heating up the water rising to the sky, also the plants perspire its water from the heating of the sun and rises to the sky, then condensation is the cooling of the droplets and condensing, weighs down the cloud with concentrated & heavier droplets and precipitation is the actually rain droplets falling to Earth.\n\nThe chemical process of cleaning the water to drink is the earthly cycle, but you want to go with human cleaning is the introduction of a sanitizing and killing bacteria in the water with chlorine and making it supposedly healthy with fluoride.  And a bunch of supposed microfilters to catch debris and bacteria.  Heating the water also helps clean it a little.

Hydrology\n\nHydrology (from Greek: Yδρoλoγια, Yδωρ+Λoγos, Hydrologia, the "study of water") is the study of the movement, distribution, and quality of water throughout the Earth.

Ice water.  Ice is the solid phase and the water is the liquid phase.

A water sport is a form of recreation where water (other than drinking water) is an essential aspect of the activity. These water sports should not be confused with watersports, as in urolagnia.

As you know, the Earth is a watery place. Estimates vary, but somewhere between 70 and 75 percent of the Earth's surface is water-covered. But water also exists in the air as water vapor and in the ground as soil moisture and in aquifers. Thanks to the water cycle (view a graphic of the water cycle) our planet's water supply is constantly moving from one place to another and from one form to another. Things would get pretty stale without the water cycle!\n\nWhen you take a look at the water around you, you see water in streams, rivers, and lakes. You see water sitting on the surface of the earth. Naturally, this water is known as "surface water." Your view of the water cycle might be that rainfall fills up the rivers and lakes. But, how would you account for the flow in rivers after weeks without rain? In fact, how would you account for the water flowing down this driveway on a day when it didn't rain? The answer is that there is more to our water supply than just surface water, there is also plenty of water beneath our feet.\n\nEven though you may only notice water on the Earth's surface, there is much more water stored in the ground than there is on the surface. In fact, some of the water you see \n\nThere is about 323 billion gallons  of surface water and about 85 billion gallons  of ground water.

who needs the water cycle with out the sun. all living things would die without the sun.

The citric acid cycle (also known as the tricarboxylic acid cycle, the TCA cycle, or the Krebs cycle) is a series of chemical reactions of central importance in all living cells that utilize oxygen as part of cellular respiration. In aerobic organisms, the citric acid cycle is part of a metabolic pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy. It is the second of three metabolic pathways that are involved in fuel molecule catabolism and ATP production, the other two being glycolysis and oxidative phosphorylation.

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:

A glacier is a moving mass of ice (frozen water).  Moving water is something you would find in a river.\n\nSometimes glaciers are referred to as "rivers of ice."  Which is true, but they flow at much much slower rates of speed.  The flow characteristics are similar in some ways, but very different in others.

Water is created by burning hydrogen.

Monsoons are flood rains that occur mainly in the Asian countries such as India, Bangladesh and others. It's part of their cycle of rainy and non-rainy seasons. The physical process would be a part of the water cycle but also coupled with atmospheric disturbances specific to the regions affected by these conditions.

H2O...two parts hydrogen and 1 part oxygen in each of the water molecules.

Do you mean water cycle?\n\nWater vapor in the air is part of the water cycle. Water vapor is a gas. Water vapor is a variable gas in the atmosphere being higher in places near water sources esp. the ocean.

The normal cycle is (very simplified): rain, transportation to sea, evaporation.\n\nThe main thing that mankind does to change this is after the rain has fallen and before it reaches the sea.  The main thing being irrigation which diverts water from the river into the surrounding land.  Obviously when water is soaked into the ground it cannot evaporate and so the 'residence time' in this part of the cycle is increased.\nBuilding damns and other structures (ie. cities) will also have similar effects by diverting the natural course of a river.\nWith global warming comes another problem.  Obviously the warmer something is the more energy it has.  This extra energy causes an unstable atmosphere leading to increased rainfall in some areas and less in others.  Rising sea temperature, which is also connected to global warming, will increase the rate of evaporation (which is why there are more hurricanes in the Atlantic).
