      • Water Cycle:
        • Evaporation- transferring of molecules from liquid to gas
          • Water Vapor: gaseous water in the atmosphere
          • Temperature- speeds up evaporation
    • Water: A World Traveler
      • Condensation:
        • Water vapor cools and becomes water droplets
      • Precipitation:
        • Any form of water that falls from the clouds
    • Water: A World Traveler
      • Water Cycle:
        • Water Evaporates
