Which statement best describes the relationship between ridgelines and terrain features?

• A. Every terrain feature originates from a valley.
• B. Ridges have no influence on surrounding terrain.
• C. Valleys originate only from ridges.
• D. Every terrain feature comes off a ridgeline.

Answer: (D)

Ridgelines serve as the backbone of terrain, shaping how other features appear around them. The high crest defines the surrounding landscape, and you can often trace features like valleys, spurs, and streams back to that ridgeline. Because of this organizing role, every terrain feature coming off a ridgeline reflects how the land tends to structure itself from the crest outward. The other statements rely on overly absolute ideas or ignore the ridgeline’s influence, whereas recognizing ridgelines as the reference from which terrain features emanate best fits how these features are arranged in the field.
