Final answer:
Rivers on gentle plains typically occupy a single channel, which allows them to flow smoothly compared to braided rivers, which have multiple channels.
Step-by-step explanation:
Rivers on gentle plains usually occupy a single channel rather than being braided. A braided river consists of a network of river channels that split and rejoin, often separated by small, temporary islands.
In contrast, a river flowing through a gentle plain typically has the tendency to meander, which is the action of scouring the outer bend of a river channel and depositing sediment on the inner bend.
As a result, the river maintains a single, winding course, as opposed to the network of channels seen in braided rivers. This single channel allows the river to flow more smoothly and slowly across the landscape.
