Which terrain feature is a low point in the ground or a sinkhole?

• A. Cliff
• B. Depression
• C. Saddle
• D. Valley

Answer: (B)

A depression is a sunken area in the ground that sits lower than the surrounding terrain and can include features like sinkholes formed by collapse or dissolution of rock. Cliffs are vertical drops and not low points. A saddle is a narrow low point between two ridges, typically a pass, and sits higher than a true sinkhole. Valleys are broad, elongated low areas, usually with a stream running through, but they aren’t single hollowed-out holes. So the term that best matches a low point in the ground or a sinkhole is depression.
