9th Grade•40 minutes
Learning Objective
我可以描述水循环的过程，包括蒸发、凝结和降水。
Key Concepts
The process where water changes from its liquid state to gaseous state is called evaporation.
Condensation is the process where water vapor combines with dust and smoke to form cloud droplets or crystals, and precipitation is when this atmospheric water falls back to earth as rain or snow.
The continuous circulation of water through evaporation, condensation, and precipitation is known as the water cycle or hydrological cycle.
