Students will be able to develop and explain a particle-level model to describe evaporation and condensation in the context of the water cycle. The water cycle depends on the processes of evaporation ...

The water cycle is the journey water takes as it moves from the land to the sky and back again. It follows a cycle of evaporation, condensation, precipitation and collection. The sun heats up ...

The water cycle follows a cycle of evaporation, condensation, precipitation and collection. Water on Earth is always moving. It is constantly being recycled. This is called the water cycle.

Water molecules travel around the planet. Over and over, they evaporate, condense, freeze, and melt in what is called the water cycle. We can imagine some of the travels the water molecules might have ...
