Meet Billy, the water droplet. He is going to show us how the water cycle works.
Billy starts off at the ocean. He is 1 out of a billion other water droplets.
Due to the heat in the atmosphere & the sun rays, Billy evaporates. Evaporation is basically vaporization. He changes from a liquid to a gas.
Now, Billy is in the clouds. In order for him to turn into precipitation, he needs to go through a process called condensation.
Condensation is basically when a droplet turns from a gas to a liquid
Due to gravity & the density of the clouds, the cloud cannot hold any more water so Billy precipitates to the ground. Depending on the atmosphere, the water droplets will either turn from a gas to a liquid & to a sold or just from a gas to a liquid.
