It is no secret that we live on a planet that is mostly covered with water. Just look at a satellite photo of earth and you will quickly get the message – planet earth is a water world but not to be confused with the 1995 movie Waterworld staring Kevin Costner. Bodies of water, living things and beings, liquids all have water in varying degrees. Most importantly, this odorless, tasteless and mostly colorless substance is essential to life on earth and is a driving force in world economies. Water can appear in three states; liquid(which is referred to as water), solid(frozen water) and gas. Test your knowledge on water with this quiz. Have fun!
