Which geographic feature is a long, narrow crest that runs along a mountain range?

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

Answer: (B)

A ridge is a long, narrow crest that runs along a mountain range. It forms the elevated backbone of the range, often acting as a watershed with streams flowing down the slopes on either side. The rocks in a ridge are typically more resistant to erosion, so the surrounding softer rock wears away and leaves this slender, elongated high feature. This is different from a peak, which is a single pointed summit; a saddle, or pass, is a low area between peaks; and a valley is a broad low region between mountains.
