What is the term for the point where a river ends by flowing into a larger body of water?

• A. Delta
• B. Estuary
• C. Mouth
• D. Confluence

Answer: (C)

Where a river ends by flowing into a larger body of water is called its mouth. The mouth is the general endpoint where the river’s flow exits into another body of water such as an ocean, sea, or lake. Depending on conditions, the mouth can also feature a delta, where sediment builds out into the receiving water, or an estuary, the tidal zone where freshwater mixes with seawater. A confluence, on the other hand, is simply the point where two rivers join upstream, not where a single river ends.
