Some water facts that might help

1. Most of the earth's surface consists of water; there is much more water than there is land.

2. Water can not only be found on the surface, but also in the ground and in the air.

3. There is the same amount of water on earth as there was when the earth was formed. The water that came from your faucet could contain molecules that Neanderthals drank…

4. The overall amount of water on our planet has remained the same for two billion years.

5. There are two kinds of water; salt water and freshwater. Salt water contains great amounts of salt, whereas freshwater has a dissolved salt concentration of less than 1%. Only freshwater can be applied as drinking water.

6. Water consists of three atoms, 2 Hydrogen atoms and an Oxygen atom, that are bond together due to electrical charges.

7. The weight of a water molecule depends on the number of moles present, as it is 18 grams per mole.

8. Water moves around the earth in a water cycle. The water cycle has five parts: evaporation, condensation, precipitation, infiltration and surface run-off.

9. In a 100-year period, a water molecule spends 98 years in the ocean, 20 months as ice, about 2 weeks in lakes and rivers, and less than a week in the atmosphere.

10. Groundwater can take a human lifetime just to traverse a mile.

11. Most of the earth's surface water is permanently frozen or salty.

12. Water regulates the earth's temperature.

13. Water freezes at zero degrees Celcius.

14. Water vaporizes at a hundred degrees Celcius.

15. Water is the only substance that is found naturally on earth in three forms: liquid, gas, solid.

16. If water changes phase its physical appearance changes due to parting of water molecules. In the solid phase the water molecules are close together and in the gaseous phase they are the furthest apart.

17. Frozen water is 9% lighter than water, which is why ice floats on water.

18. A litre of water weighs 1.01 kilograms.

19. It doesn't take much salt to make water "salty." If one-thousandth (or more) of the weight of water is from salt, then the water is "saline."

20. Saline water can be desalinated for use as drinking water by going through a process to remove the salt from the water.

21. When water contains a lot of calcium and magnesium, it is called hard water. Hard water is not suited for all purposes water is normally used for.

22. To determine water quality certified agencies take samples that are tested in a laboratory. The samples are tested on various factors, to determine if they suffice water quality standards.

23. Each country has its own water quality standards that determine to which degree water should be purified, depending on the purpose it will be used for.

Hey,

I did some work in university about climate change. I was surprised to find out that one of the biggest problems we may face in the future is a scarcity of drinking water.

If you do a search on google you get lots of sites with info about it, this article from the BBC is a good place to start.

and you can get more info from the UNEP website at
