If there is no pressure to move water how does a puddle eventually disappear after a rainstorm ends

Answer: A puddle will eventually disappear after a rainstorm ends due to evaporation. This is caused by the heat of the sun, which converts the liquid water into steam (a gas) and evaporates.

The rain puddle will eventually either evaporate into the air or get absorbed into the ground.

Explanation from the Lesson:

Think about a puddle after a heavy rain. That water is not going anywhere because once the rain has stopped, there is no action. The puddle will not stay there forever; eventually, it will evaporate or sink into the ground.
