As we all know from school the earth’s water is constantly in movement, the water cycle or hydrologic cycle, describes the movement of water above, below, and under the earths surface. As the name ‘water cycle’ implies there is no beginning or end to this process and while water may change state from liquid, to vapour, to ice depending on the part of the water cycle that you are looking at, the amount of water on Earth remains constant over time. Unfortunately there are now more and more people on the planet to share this limited resource with, and the only way to deal with the growing shortage is to conserve as much water as possible by using what we have in the most responsible way.
