The questions

Up, Up, and Away

  1. What gives the water cycle its energy?The sunEasy
  2. When liquid water is heated and turns into a gas, what is that called?EvaporationEasy
  3. What do we call water when it is an invisible gas in the air?Water vaporMedium
  4. Name a place on Earth where lots of evaporation happens.The oceanMedium
  5. When water evaporates from the leaves of plants, what is it called?TranspirationHard

Cloud Making

  1. What do we call water vapor cooling and turning back into tiny drops of liquid?CondensationEasy
  2. What are clouds made of?Tiny drops of water (or ice)Easy
  3. Why do drops form on the outside of a cold glass on a hot day?Water vapor in the air cools and condenses on the glassMedium
  4. As air rises high into the sky, does it get warmer or cooler?CoolerMedium
  5. What do we call a cloud that touches the ground?FogHard

Falling Down

  1. What is it called when water falls from clouds to the ground?PrecipitationEasy
  2. Name two kinds of precipitation.Any two: rain, snow, sleet, hailEasy
  3. What kind of precipitation falls as soft, frozen ice crystals?SnowMedium
  4. Why do water drops fall out of clouds?They join together and get too heavy to floatMedium
  5. What kind of precipitation falls as hard balls of ice, often during thunderstorms?HailHard

Where It Goes

  1. What is it called when water gathers in oceans, lakes, and rivers?CollectionEasy
  2. Where is most of Earth's water found?The oceanEasy
  3. What do we call rain water that flows over the ground into streams and rivers?RunoffMedium
  4. What do we call water that soaks into the soil and is stored underground?GroundwaterMedium
  5. Can the same water go through the water cycle again and again?Yes, Earth keeps reusing the same waterHard

Big Picture

  1. What are the three states of water?Solid (ice), liquid (water), and gas (water vapor)Easy
  2. What is the solid form of water called?IceEasy
  3. Put these in order: precipitation, evaporation, condensation.Evaporation → condensation → precipitationMedium
  4. Why is it called a water 'cycle'?It repeats over and over with no beginning or endMedium
  5. If the sun stopped shining, which step of the water cycle would slow down the most?EvaporationHard
