CHALLENGE (not a quiz question): Explain how the water cycle an example of a physical change.

What is YES, it is a physical change, because water changes from a liquid/solid when it precipitates, to a gas when it evaporates, then forms back into a liquid when it condensates. Then the process repeats again with the same substance, WATER!
