Water cycle

"The water cycle is often referred to as a 'closed system' because the same water has been circulating since the earliest days of the planet. No water is added and none is taken away. Humans interact with the water cycle in many ways, some of which pollute the water and disrupt the cycle."

The water cycle consists on many stages such as:

Evaporation- the system where water is transferred into water vapor.

Transpiration- the system where water is consumed by plants and then passed into the atmosphere.

Condensation- the action of water vapor changing into a bead of liquid water in the structure of dew, fog or clouds.

Precipitation- all of the forms of water, if liquid (e.g. rain) or solid (e.g. hail), that fall from clouds and the ability to land on the ground.

Catchment area

"A catchment is an area of land from which water drains into a river. Every part of the earth's land surface is part of a catchment. Neighbouring catchments are divided by watersheds, and rivers are arranged within catchments in drainage patterns."

  • The Amazon Water basin has 64 different rivers or streams.                                   { The red high-lights the different names of streams or rivers }
  • The Amazon watershed is found just at the highest point of Yerojapa.             { Peru }
  • You can just see off the coast of the Atlantic ocean,where the Amazon river begins.   { Highlighted in a dark blue }
  • The drainage pattern is surrounding the system of the Amazon river.                         { The yellow covers the Amazon River }
  • The Amazon flows from the Pacific ocean toward the Atlantic ocean.            { Where the arrows show }

Three types of water

Blue Water

Blue water: is described as being fresh water on the earth's surface and ground water as well. These also can be found in fresh water lakes, rivers and aquifers.

Green Water

Green water: is the term used to explain the water that's stored in the soil or found in vegetation.

Gray Water

Gray water: is waste water that comes from domestic activities, activities such as washing clothes, dishes and taking a shower. This water can also be recycled and be used to water gardens or fields.

Water use in Australia

"In 2008-09, Australia's total domestic water use was 14101 gigalitres { 1 gigalitre is approximately the amount of 500 Olympic swimming pools. }"

How these waters are used in Australia:

Blue water is used in Australia because of the fresh water we drink and use in our dams spread across each state, Green water is found in the different farms and soil that surrounds us, everywhere in the world, including Australia, Gray water is found in houses from dishwashers,showers and washing machines and in fact recycled water is used to water botanical gardens and football grounds all over Australia.

Water Footprint

"A water footprint is the total volume of fresh water used by an individual, a household, a business, a community or a country."

Bottled water

Plastic bottles are made out of oil, and through the making of these bottles, creates hundreds upon hundreds of green house gases. Many times more than the average tap water.


Virtual Water

"Virtual water is the water used in the production of goods and services we use."

Trade in Virtual water

Is the scheme where an item that contains virtual water is exchanged, so is the water that was used to create the item.

How the trade works

If, for example a country imports 1 tonne of bran, that country would save approximately about 1300 cubic meters of its own water. If the water is limited within that country, it can use the water that it saves for other purposes. However, if the water is limited in the exporting country, it has exported 1300 cubic meters of water, making it no longer usable for other purposes.
