what are the 4 main steps of the water cycle?

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

We never get new water here on earth..it's just recycled. The water cycle defined is "Transition and movement of water involving evaporation, transpiration, condensation, precipitation, percolation, runoff, and storage."\n\nWater falls in the form of precipitation (snow, rain, etc). Some of it seeps into the ground that makes up our water aquifers (perculation), some is in the form of runoff (rivers, streams), eventually water makes its way to lakes, ponds, oceans, etc and is stored. Some water is taken up by plants and is stored there. It leaves "storage" when the water evaporates and through transpiration in plants (plants lose water through their leaves which is why they seem especially prone to wilting on a hot windy day).\n\nCondensation is when water goes from a gaseous state back to a liquid state. An example of this putting your breath on a cold window or mirror and watching the water droplets form.\n\nHope this helped. It's a simplified explanation, but it will get you started.

1. Fill the five gallon jug.\n2. Pour water from the five gallon jug into the three gallon jug. That will leave you with two gallons in the five gallon jug.\n3. Empty out the three gallon jug.\n4. Pour the remaining two gallons from the five gallon jug into the three gallon jug.\n5. Fill the five gallon jug. \n6. Pour water from the five gallon jug into the three gallon jug. That will leave you with 4 gallons of water in the five gallon jug.

Evaporation: Water from a lake, stream or any body of water forms into a gas and rises up into the sky.\n\nCondensation: The evaporated water cools down in the higher atmosphere and forms small molecules. Many of these small molecules stick together to form clouds.\n\nPrecipitation: Once the cloud is too big and can't hold that much water, the water falls down as either rain, hail, sleet, or snow, depending on the temperature.\n\nCollection: The water falls into a body of water and collects there. Then it evaporates into the air again and the water cycle starts all over.

Water Systems:\n\nhttp://www.ec.gc.ca/water/images/nature/prop/a2f2e.jpg\n\n95% of Earth's water is Salt Water leaving 5% as Fresh Water.  Nearly all of the Fresh water is in the form of Ice or underground.\n\nThis site appears to have a lot of data as well as activities for learning.\n\nhttp://members.aol.com/bowermanb/water.html

In the water cycle, water falls to the earth in the form of precipitation.  Plant roots absorb the water, which is then transported through the xylem vessels to the leaves.  There, photosynthesis takes place.  Each water molecule is split up, forming hydrogen ions, oxygen, and electrons.  The electrons are used to create ATP for the dark reactions.  In end, a three-carbon sugar is formed, which combines with another three-carbon sugar to form glucose.  Besides photosynthesis, water seeps into the ground and bodies of water.  It stays there for organisms to use.  Much of it eventually evaporates.\nCO2 is used in photosynthesis to form glucose (the glucose's carbon is from CO2).  Glucose is eventually broken down to form ATP.  Animals store glucose in the form of gylcogen, whereas plants tore it in the form of starch.  Carbon is also present in the atmosphere in the form of other gases (including, I think, greenhouse gases).  It is also present in decaying organic matter, returning to the atmosphere in the form of gas.
