A tributary is a river that ends at the place where it runs into another river, and feeds the bigger one.
A river that merges with a bigger one
A tributary is a smaller stream or river that flows into a larger river or lake, enhancing the overall water system by combining its flow with the main body. This process is important for shaping landscapes and supporting ecosystems. For example, the Missouri River is a tributary of the Mississippi River, contributing to the larger water system.
