The water cycle Presentation Transcript

  • 1. The Water Cycle
    Ms. Heller
  • 2. What is the water cycle??
    The water cycle is the repeated movement of water through the environment in its many forms.
    The amount of water in the water cycle doesn’t change! It is continually recycled in a never-ending process and it has been reused over and over throughout the entire history of the Earth.
  • 3. Evaporation
    • Evaporation is the process of liquid water changing into a gas.
    • 4. The sun heats the water and causes molecules of water to fly off
    • 5. These molecules of water vapor rise up into the atmosphere.
    • 6. NOTE: the sun is the driving force of the water cycle, the hotter it is the faster evaporation will occur.
  • Condensation
    • Condensation occurs when water vapor molecules begin to cling together.
    • 7. When enough molecules cling together in the cool atmosphere, it forms a cloud
  • Precipitation
    • The cloud’s water molecules will continue to cling together until they are very heavy.
    • 8. Then, they begin to fall back toward the Earth in the form of rain, snow, sleet, or hail
  • When precipitation lands on the ground…
    It can becomerunoff
    OR
    It can become groundwater
  • 9. Runoff
    • When precipitation lands on the ground it can run off the surface and collect into rivers or streams that will then carry the water back to the ocean.
  • Groundwater
    • Some water is absorbed into the ground and can stay stored in the ground for many years.
    • 10. This water will eventually return to the ocean as well.
    Groundwater
  • 11. We have to give credit when we use the work of others……
    I would like to thank Michelle Henry for allowing us to use her water cycle diagram for our learning.
