Do you have any info on the natural water cycle?

The water cycle: water evaporates on the Earth's surface (oceans, plants...), gets into the athmosphere, forms clouds then falls back to Earth as rain or snow, and the cycle restarts.

Author of the true power of water, i have the book, really fascinating!

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.

The movement of water around, over, and through the Earth is called the water cycle.The water cycle—technically known as the hydrologic cycle—is the continuous circulation of water within the Earth's hydrosphere, and is driven by solar radiation. This includes the atmosphere, land, surface water and groundwater. As water moves through the cycle, it changes state between liquid, solid, and gas phases. Water moves from compartment to compartment, such as from river to ocean, by the physical processes of evaporation, precipitation, infiltration, runoff, and subsurface flow. Movement of water within the water cycle is the subject of the field of hydrology.

I'm not sure what level of technical knowledge you are looking for, but here are a few ideas:\n\nThe water cycle\nThe greenhouse effect\nDepletion of the ozone layer (NOT the same as above) \nFood chain based around a coral reef\nWaste disposal techniques\nPros and cons of alternative fuels\nEl Nino as an environmental phenomenon\nWhat if sea levels change?\n\nGood Luck!

I forgot about the water difference ... the one that comes first to my mind is the "Stars" ... you will not have the "North Star" in the Southern Hemisphere ... honestly, I have no idea how Magellin navigated on his journey.

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

try to search at google or just try to browse these websites: \nhttp://marinebio.org/Oceans/TheForests/\n\nhttp://www.answers.com/topic/alga\n\nhttp://www.whoi.edu/redtide/\n\nhttp://tuberose.com/Algae.html\n\nhope those would help

Try this website, it has some good explanations of things like total dissolved solids, dissolved carbonates, boron, and other things often found in water used for growing plants. There's even a little information that is specific to grasses. \nhttp://www.ext.nodak.edu/extpubs/ageng/irrigate/eb66w.htm#plants\n\nBy the way, I found this using the search terms:\nirrigation water\nSo if you want to duplicate my search and see other results this should get you going.

One famous water form is called the sea I think. Nobody's ever seen it though

Yes. And lakes, land masses, nay number of thing. (The larger the object the greater the effect, the less viscous the object the greater the effect.)\n\nLots of details at source below.
