Which of the following is a major terrain feature that forms a long elevated crest?

• A. Hill
• B. Ridge
• C. Valley
• D. Saddle

Answer: (B)

Ridges are long, narrow crests of high ground that run for considerable distances, forming a continuous elevated spine. The key idea is that the feature extends in length along the landscape, with slopes dipping away on either side into valleys. That combination—height plus an extended crest—defines it as the long elevated crest described. A hill is an isolated, rounded high point, not a long crest. A valley is low ground between highs. A saddle is a low point or pass between two ridges.
