    Watercycle I I Watercycle I I Presentation Transcript

    • Water, Water Everywhere!
    • How Much Water is on Earth?
      • Water covers 70% of the earth's surface.
      • Water is stored in lakes, glaciers, underground, or in living organisms.
      • The Earth has only a limited amount of water
    • Where Does Water Come From?
      • The Earth’s Water is recycled, which means that it is reused over and over.
      • Because water is always being reused, it has been around as long as the Earth has.
      • The water in your drinking class could be the same water George Washington drank!
    • How is Water Recycled?
      • Water is continuously circling from land, to sky and back again.
      • This journey is called the Water Cycle!
      • The Water Cycle has no beginning or end!
    • How Does the Water Cycle Work?
      • During the water cycle, the sun heats the Earth's surface, causing water to evaporate and rise to the atmosphere.
      • There, it cools and condenses into liquid droplets.
      • These droplets fall to the earth as precipitation.
      • Water is then collected in rivers, streams, oceans, plants and and animals.
      • The Cycle then starts all over again!
    • How Does Water Change During Each Stage?
      • When water evaporates it heats up and turns to gas.
      • While in the atmosphere, this gas cools and forms into clouds.
      • Clouds grow and during precipitation water falls as either liquid (rain) or solid (snow/ice)
    • How Does This Water Get to My Kitchen Faucet?
      • Water is collected in rivers, lakes, wells and reservoirs.
      • Public drinking water systems pump water through an underground network of pipes.
      • Big pipes deliver water to each neighborhood, and then the water is split into medium pipes and smaller pipes for each street and each home.
