Question

What may form when falling precipitation runs off the surface of the ground? Explain how the form of precipitation may affect runoff.

I don't understand what they are asking. What do they mean by "What may form?" does it mean like a puddle? or mudslide? or something?

Yes, you're on the right track. It could also be a wadi.
