Which feature is defined as a dip or low point along the crest of a ridge?

• A. Vertical cliff.
• B. Broad valley between hills.
• C. High point on a ridge crest.
• D. Dip or low point along the crest of a ridge.

Answer: (D)

A saddle is a dip or low point along the crest of a ridge. This describes the exact feature being asked for, making it the best answer: it identifies the low point that sits along the ridge line, between higher points. In terrain terms, saddles (also called cols or passes in different contexts) are the narrow, lower spots you’d find running along a ridge, often serving as a natural route through mountainous terrain. The other features do not fit this description: a vertical cliff is simply a sheer drop, not a low point along the crest; a broad valley between hills is a wider low area that lies away from the immediate crest; a high point on a ridge crest is the opposite—a peak, not a dip.
