Which terrain feature is commonly associated with running water in a landscape?

• A. Plain
• B. Valley
• C. Ridge
• D. Plateau

Answer: (B)

Running water carves the landscape, creating long, low stretches where a stream or river flows. As water moves, it erodes banks and bed, deepens channels, and transports sediment, forming valleys that are the natural home for flowing water. This direct link—water shaping and occupying a valley—makes it the terrain feature most closely tied to running water. In contrast, a plain is a wide, flat expanse with little relief, a ridge is a narrow, high crest along a divide, and a plateau is an elevated flat area; none of these are defined primarily by the action of running water in the same way a valley is.
