Weather and Climate Quiz

During a science experiment, Jaiden and Aubry observed a puddle of water disappearing on a sunny day. What is the process called when water changes from a liquid to a gas in the water cycle?

• Condensation

• Evaporation

• Precipitation

• Infiltration

Answer explanation

The process when water changes from a liquid to a gas is called evaporation. This occurs when the sun heats the water, causing it to turn into vapor and disappear, as Jaiden and Aubry observed.
