Which statement about contour lines is generally correct?
Correct answer: B. They normally do not intersect one another
- A. They always intersect at right angles
- B. They normally do not intersect one another
- C. They are equally spaced on every slope
- D. They always form straight parallel lines
Explanation
Contour lines representing different elevations normally do not intersect. They may appear to meet in special cases such as a vertical or overhanging cliff, but they do not generally cross ordinary ground surfaces.

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.
