What term describes the place where two rivers join to form a larger river?

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

Answer: (D)

Confluence is the place where two rivers meet and join to form a single, larger river. This junction is about the coming together of streams to create a continuous watercourse, not about where a river ends or the landforms formed at its mouth. For example, the confluence of two tributaries creates a new, combined river downstream. In contrast, a delta forms from sediment deposited where a river meets a body of water at its end, an estuary is the tidal zone where freshwater mixes with seawater at the coast, and the mouth is simply the downstream end of a river as it flows into another body of water. So the term describing the joining point of two rivers is confluence.
