A bowl of water was placed on a table in a science lab. Students observed the water level for several weeks, and found that it decreased over time. What most likely happened to the water?

• The water transpired

• The water condensed

• The water evaporated

• The water precipitated

Which BEST describes the relationship between the sun and the water cycle?
