Which of the following best describes a ridge?

• A. A sloping line of high ground
• B. A stretched groove of land
• C. A less developed valley
• D. A horizontal angle measured from south

Answer: (A)

A ridge is defined as a long, narrow elevation of land, characterized by a continuous crest or summit that generally slopes down on either side. Therefore, describing a ridge as a sloping line of high ground captures the essential features of this geographical formation. It implies that the ridge has height relative to the surrounding landscape and that it extends over a distance, making it distinct and prominent.

The other descriptions do not accurately represent the characteristics of a ridge. A stretched groove of land, for example, suggests a depression rather than an elevation. A less developed valley refers to a low area between hills or mountains, which contradicts the concept of a ridge as being elevated. A horizontal angle measured from south pertains to navigational or surveying terminology and does not relate to the topographical description of a ridge at all. Thus, the first choice precisely aligns with the definition and physical characteristics of a ridge.
