  • What is the process called in which plants take in water through their roots and then release it in the form of water vapor through their leaves?
    transpiration
  • True or False: Rain is precipitation,
    True
  • What is the process in which water vapor cools down, comes together to form a cloud, and turns back into a liquid?
    Condensation
  • Look at the picture. Explain how the ocean interacts with the air to eventually bring rain to fall over the house. Draw a picture to help explain your thinking.
    The ocean gets heated by the sun which causes water vapor to rise into the atmosphere (air). As the water vapor rises, it cools and condenses to form clouds.
  • True or False: Most of the water on Earth is salt water. The little amount of fresh water on Earth is mostly frozen.
    True
  • True or False: Precipitation is the heating of liquid water and converting it to water vapor.
    False
  • If the ocean temperature stays the same but the air in atmosphere above the ocean becomes very cold, do you think it will rain more or rain less?
    It will rain more because the cold air is leading to more condensation happening.
  • What is the process called in which clouds release moisture allowing it to fall to the ground.
    Precipitation
  • True or False: You have to dig to reach groundwater.
    True
  • What percentage of water on Earth is NOT salt water?
    3%
  • What is the name for precipitation that runs off the landscape into the ground or back into the surface water that it came from?
    Runoff
  • List 3 examples of surface water.
    Lakes, Rivers, Streams, Ponds, Puddles
  • What is the process called in which liquid water is heated and changed into water vapor?
    Evaporation
  • Explain why it's important that we work hard to conserve Earth's fresh water.
    It’s important to protect the Earth’s fresh water because there is so little of it. Humans need fresh water for drinking and bathing.
  • What are the four forms of precipitation?
    rain, snow, sleet, hail
