Today we will be learning about the water cycle. I, a water droplet, will go through this cycle while we learn about each part of the cycle.
You don't see me now, I've changed because of evaporation! Evaporation is the process of water changing state from a liquid to a gas. I absorb energy to change into water vapor, but I'm still water. In this process, I cool the surrounding environment.
Now I'm inside a cloud! Clouds are formed by a process called condensation. Condensation is the when water changes state from a gas to a liquid. It has a warming effect since it releases heat.
The next part of the cycle is precipitation, in which I come down in the atmosphere as either a liquid or a solid, in the form of snow, rain, sleet, or hail.
However, not all of us will flow in the river. Some of us are absorbed into the soil and rocks. This process is called infiltration.
Next is runoff. During runoff, I, along with other water droplets, flow off of a surface in a stream or river.
And there you have it, the water cycle! I go through this cycle again and again: evaporation, condensation, precipitation, runoff, and infiltration. However, I'm always yours truly, water.
