Where do rivers and streams get their water from? 3 sources

From its source to the SeaA stream begins at its headwaters, often in areas where there is constant runoff of rain or melting snow or an underground spring.The stream continues to flow and combines with other streams (called tributaries) until they become a river systemThe river will flow until its mouth (the end of the river) opens into the ocean, lake or seaThe mouth of a river creates a Delta (a layer of sediment)

Summary QuestionA Changing River
200 years ago a stream was set as a boundary on some land. Now surveys show that this river is no longer used as an accurate boundary. Why?
