Drops of Wisdom About WaterDid you know:♦ Of all the water on Earth, 97% is saltwater, 2% is ice and only 1% is fresh water.♦ The amount of water on Earth has remained basically the same. We drink the same waterthe dinosaurs drank.♦ Water is the only natural substance that exists in three forms: liquid (water), gas(vapour) and solid (ice).♦ Water has no taste.♦ Water is colourless.♦ Water is odourless.♦ The boiling point for water is 100 o C.♦ The freezing point for water is 0 o C.♦ Water is made up of two hydrogen and one oxygen atoms, in other words H 2 O.♦ The three forms of water are important parts of the hydrological cycle (Water Cycle).This is the never ending cycle of water from the Earth’s surface to the atmosphere(evaporation) or from trees and plants (transpiration) to form clouds (condensation)before it falls back to Earth as rain, snow or hail (precipitation).♦ Water that exists in underground sources is called ground water – across Australia, bores(wells) have been dug so that people can ‘tap’ into these sources for their fresh watersupply.♦ A tap uses approximately 20 litres per hour – even a slow dripping tap will use five litresper hour.4
