​Water moving across the land is called runoff. Surface runoff is a direct result of precipitation, such as rain or snow.

​

If precipitation is not absorbed into the ground, it flows over the land as surface runoff. About one-third of precipitation becomes surface runoff. Time, weather, and geography affect its flow. Most surface runoff eventually makes its way into established bodies of water, such as lakes and rivers.
