872 Views 15 Votes 23 Comments

We hear a lot about wasting water as well as contaminating it, as if we can use up what will be needed in the future or as if scientific technology is always needed to clean it after it is used. Naturally, we should be good stewards of all our planet’s resources, but do we really understand how the water cycle was designed? Could fear mongering cause us to misunderstand how the earth’s water system really works?

Check your knowledge of how planet earth’s water cycle works in this quiz then, in the comments below, let us know if you learned something new.

  • Question of

    Why is earth’s water system called a closed system?

    • Because our water always follows the same paths in its cycle.
    • Because earth’s water is always recycling through it’s cleaning system.
    • Because water is always being contaminated.
  • Question of

    Earth’s water system is sometimes called

    Water continuously moves through earth’s water system…

    • True, it is always moving through the cycle.
    • False, sometimes there are droughts.
  • Question of

    What are the three major methods of movement in earth’s water cycle?

    • Clouds, bodies of water on earth’s surface, and wind.

  • Question of

    When moving through the cycle water changes…
