A valley on a map is defined as what?

A valley on a map is defined as what?

• A. A broad plateau
• B. A river mouth
• C. A stream course with limited extent of level ground bordered by higher ground.
• D. A man-made boundary.

Answer: (C)

Valleys are low-lying corridors carved by running water, with a relatively flat floor bounded by higher terrain. On maps, this is defined as a stream course with limited extent of level ground bordered by higher ground. The presence of a flowing water path and the surrounding rising ground distinguish it from other features. A broad plateau would be flat land at high elevation, not a valley. A river mouth is where a river empties into another body of water, not the valley itself. A man-made boundary is artificial, not a natural landform.
