Contour lines that fall between index lines and are the next solid line after the index are called?

Contour lines that fall between index lines and are the next solid line after the index are called?

• A. Intermediate Contour Lines
• B. Supplementary Contour Lines
• C. Index Contour Lines
• D. Contour Lines

Answer: (A)

The lines that fill the gap between the heavy, labeled index contours are called intermediate contour lines. They sit between index contours and represent the elevation steps at the standard interval, giving you a clearer sense of slope and terrain. Supplementary contour lines are extra, often dashed lines used in some maps to show additional elevation steps when spacing is tight or when detail is needed; that’s a different feature. A generic contour line could be any line of equal elevation, but the specific term here is intermediate contour lines.
