Water

1. Surface Water

   • River
     • Flow of Water
     • Rivers flow down to Lakes an Oceans
     • It is bigger and depper than a stream
   • Stream
     • It is smaller than a river
   • Lake
     • Area surrounded by land
   • Glacier
     • Area of moving ice
     • Glaciers have snow and ice
   • Ocean
     • Huge area of salt water
     • Ocean= World Ocean
       • Pacific Ocean
       • Atlantic Ocean
       • Artic Ocean
       • Indian Ocean
       • Southern Ocean

2. The Water Cycle

   • Evaporation
     • When the sun heats Water, the Water evaporates, moving up into the atmosphere as water vapour.
   • Condensation
     • The Water vapour cools and condenses. Drops of liquid water begin to form and join together to form clouds.
   • Precipitation
     • When the Clouds cool and become heavy, drops of Water start to fal in the form of precipitation.
   • Collection
     • This Water collects in Rivers, Lakes and Oceans and is also absorbed into the ground as groundwater.

3. The three states of Water

   • Gas

     • Fishing
     • Swimming
     • Water - skiing
     • Sailing
     • Scuba diving

7. Hydrometer

   • The energy of moving water produces electricity

8. Agricultural use

   • We use 70% of Water - for irrigation. Watering the plants

9. At home

   • A person uses aproximately 50 litres of Water per day
     • Drinking
