Final answer:
Surface runoff and snowmelt produce water that can flow across the surface, contributing to the water cycle.
Step-by-step explanation:
Surface runoff and snowmelt produce water that can flow across the surface. Surface runoff is the flow of fresh water either from rain or melting ice. It can make its way through streams, lakes, and eventually reach the oceans. Snowmelt refers to the melting of snow, which also contributes to surface runoff.
