                            Explain all the steps of the water cycle using correct vocabulary.
                            Evaporation- sun heats up water molecules and they become a gas and rise up in the atmosphere. 
Condensation- as water molecules rise and cool off in the sky, the condense and turn back into water to make clouds.
Precipitation- falls from the sky when clouds become too heavy( hail, sleet, rain, snow)
Run-off - when precipitation returns to the Earth, gravity causes it to run off to the lowest areas on Earth (rivers)
