If the contour lines on a map are closely spaced, the terrain represented is generally:
Correct answer: C. Steep
- A. Nearly level
- B. Uniformly depressed
- C. Steep
- D. Without elevation change
Explanation
Close contour spacing indicates a large change in elevation over a short horizontal distance, which represents a steep slope. Widely spaced contours indicate gentler ground.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
