| The phases of the water cycle are ______, ______, ______, and ______. | Evaporation, condensation, precipitation, and collection |
| _______________ is the phase where liquid water heats up and becomes a gas, or water vapor. | Evaporation |
| The the water vapor (gas) ______ down and condenses with other water droplets (liquid) to form a cloud. | Cools |
| What is the phase where water vapor cools down and condenses with other water droplets (liquid) to form a could? | Condensation |
| When condensation happens and forms a cloud close to the ground, it is called ______. | Fog |
| The next phase happens when the water droplets become too _____ and fall back down to the Earth. | Heavy |
| What is the phase where water droplets become to heavy and fall back down to Earth? | Precipitation |
| What are the four forms of precipitation? | Rain, sleet, snow, and hail |
| When it is so cold that the water vapor goes straight from gas to solid, that is how ____ happens! | Snow |
