Elevation in the landscape?

Elevation in the landscape?

• A. Elevation
• B. Altitude
• C. Contour
• D. Gradient

Answer: (C)

Contour lines on a map show elevation across the landscape. Each line connects points that are the same height above a reference, usually sea level. This is why contour is the best choice: it directly encodes how high the land rises or falls, letting you read the terrain’s shape, such as hills, valleys, and plateaus, from the map. Elevation or altitude refer to the height at a specific point, not the representation itself, and gradient describes how quickly the elevation changes (the slope) rather than the visualization of elevation across an area. Contour lines also reveal steepness through how close together they are—the closer the lines, the steeper the slope, and closed loops often indicate a peak or a depression.
