ONCE UPON A TIDE


Water, Water Everywhere

Well, almost everywhere. About 70% of the Earth’s surface is covered in water, but less than 3% of it is fresh water that we can use.

  • Every living thing needs water. No plant, animal or human being can survive without it. 
  • Believe it or not, the water we use today is the same water that was around when the dinosaurs lived. It just keeps on moving in a never-ending water cycle.
  • 97% of the water on Earth is found in the oceans as salt water. There are five oceans: Pacific, Atlantic, Indian, Arctic, and the Antarctic, sometimes called the Southern Ocean.
  • Some scientists think the world’s largest reptile is the saltwater crocodile or the Komodo dragon.  But the leatherback turtle looks like the winner.  It can weigh as much as five refrigerators!
