What feature distinguishes a hill from a mountain in contour mapping?

• A. Concentric contour lines
• B. Less pronounced elevation changes
• C. Steepness of the sides
• D. Radius of the base

Answer: (A)

A hill is typically distinguished from a mountain in contour mapping primarily by the presence of concentric contour lines. Contour lines indicate elevation on a map, and when they are found in a series of closed loops that get smaller towards the summit, they signify a hill. This pattern reflects a gradual rise and gentle slope. When examining higher elevations, such as mountains, the contour lines may still be concentric but can also indicate more complex terrain and steeper slopes. While steepness, elevation changes, and base radius are important in defining the characteristics of hills and mountains, the defining feature visible on contour maps is the pattern of the contour lines themselves. Concentric lines suggest a more uniform, rounded elevation shape typically associated with hills, whereas different patterns in mountains may denote varying steepness and terrain complexity.
