Question

On a standard topographic map, what is the vertical distance between two adjacent contour lines called?

• A. Contour Interval
• B. Elevation Gradient
• C. Index Value
• D. Scale Factor

Answer 1

Answer:

A. Contour Interval

• This is the constant vertical height difference maintained between consecutive lines on a map. • The Contour Interval is the specific mathematical increment of elevation change between any two successive lines. • While the horizontal distance between lines on a map varies based on the steepness of the terrain, the vertical distance (the interval) is a fixed value established in the map's legend to ensure consistency across the entire landscape.
