  1. most of the world's water is in the salty oceans, but this water is unsuitable for land animals and plants, which require fresh water. through the  Water Cycle, however, water evaporated from the oceans is carried into the air as water vapour, an invisible, dry substance which behaves like a gas. this water vapour may condense to form clouds which are blown by winds over land areas, from these clouds, rain, snow, sleet and hail fall on land areas, providing life-giving fresh water . the water cycle is completed when water is returned to the oceans by rivers.


  2. Water is made up of Hydrogenx2 and Oxygenx1

    You can separate them, but you can never get them back together. No matter/energy is ever created or destroyed. All that we have today was never less or more than it was back then. Water goes through the water cycle. You can't create water. Water goes through the water cycle. It is evaporated. Then condenses into the clouds in a process called condensation. The is precipates(rains) back to earth, and reuse it. You get an A+ if you write what I just typed.

  3. How would you go about creating water?

  4. As noted above, the water cycle is an important system to help support life on Earth.  Water falls from the sky, is used by creatures, evaporates, and falls again.  This is vital to life.

    But how is water used by creatures?  It's not just a lubricant: it plays a vital role as a building block in many living molecules.  

    Water is created and broken apart on a daily basis.  The most common way this is done is photosynthesis:

    6 CO2(g) + 6 H2O(l) + light → C6H12O6(aq) + 6 O2(g)

    in other words... six moles of carbon dioxide, six moles of water, and a light source to provide energy become a mole of glucose (a sugar), and six moles of oxygen.  The water molecules are actually broken down and used with the carbon to build the glucose.

    (It also gets broken apart in animals, but the photosynthesis reaction is less complex.)

    The water is then remade when the glucose (or any hydrocarbon-based fuel) is burned.  The energy is released as heat and light, and the molecules revert to a simpler form:  CO2 + H2O.

    Note that these are also the byproducts of burning fossil fuels such as oil, coal and natural gas, as well as carbohydrates such as sugars, starches, and alcohols.  All of these are just hydrocarbons in different forms.

    Another way to break down water molecules is through electrolysis.  This uses an electric current to add enough energy to a water-based solution to tear the molecules apart, creating H2 gas and O2 gas.  Mixing these gases back together and adding a match will give back (most of*) that energy in a violent explosion.

    In general, burning any hydrogen-containing compound (whether it's as simple as H2 gas, or as complex as glycogen) will result in the formation of water.  After all, burning really just means 'reacting with oxygen.' **

    * In every process, some energy is lost as waste heat, meaning that you end up with less usable energy than you began with.  The usable energy + the waste energy, however, always exactly equals the energy originally put in to the system, as explained by the law of conservation of energy.

    ** For a good demonstration of that, try burning steel wool.  You can watch it react with oxygen and turn into rust before your eyes.

  5. Drinking water is recycled.

    Even ocean/lake water is recycled.  The moisture goes into the atmosphere and is recycled as rain.

    "We can start our examination of the cycle with the oceans, which hold over 97% of the planet's water. The sun causes evaporation of water on the surface of the ocean. The water vapor rises and condenses into tiny droplets which cling to dust particles. These droplets form clouds. Water vapor usually remains in the atmosphere for a short time, from a few hours to a few days until it turns into precipitation and falls to the earth as rain, snow, sleet, or hail."
