Explanation:
Detailed explanation-1: -A tributary is a freshwater stream that feeds into a larger stream or river. The larger, or parent, river is called the mainstem . The point where a tributary meets the mainstem is called the confluence.
Detailed explanation-2: -The place where a river enters a lake, larger river, or the ocean is called its mouth. River mouths are places of much activity. As a river flows, it picks up sediment from the river bed, eroding banks, and debris on the water.
Detailed explanation-3: -These smaller streams are called tributaries. Streams create channels by wearing down rock and carrying it and other sediment downstream. This process is called erosion.
