Where does a river begin?

• A. Source
• B. Alluvium
• C. Ox Bow Lake
• D. Mouth

Answer: (A)

The starting point of a river is its source. This is where the river’s flow first forms, often in upland or mountainous areas where water from springs, rainfall runoff, or melting snow converges to create the initial stream. From this headwater, the river collects more water as tributaries and flows downstream toward its end. The mouth is the opposite end, where the river enters a larger body of water such as a sea or lake. Alluvium refers to sediment deposited by the river, commonly in floodplains, and oxbow lakes are former meanders that have been cut off from the main channel.
