    Water Table
  • Large area of ice that permanently covers land
    Ice Cap
  • Is water a solvent or solute? Does water have a weak or strong ability to dissolve substances?
    Solvent, Strong
  • Water that flows over Earth's surface (from precipitation/snowmelt)
    Runoff
  • Describe pure water is 4 ways. What particles is it composed of?

  • Water that seeps through soil and cracks in rock. Source of water for underground springs and wells
    Ground Water
  • Step 2 of water treatment
    Addition of chemicals, Alum+water=floc
  • A continuous movement of water above, on, below the Earth's Surface. Driven by
    Water Cycle, Sun
  • Sublimation changing from? Heat? Example?
    Solid to gas, heat in, tree car freshner
  • Deposition changing from? Heat? Example?
    gas to solid, heat leaves
  • Step 5 of water treatment
    Disinfection
  • What am I? Mechanical pressure forces water through a membrane (filter)
    Reverse Osmosis

    Liquid to Gas, heat absorbed
  • Step 6 of water treatment
    Storage
  • The sticky clumps of small particles that form when alum is added to water are called
    Floc
