Question

Define the characteristics of Contours _________________.

• A. Contour lines must close , not necessarily in the limits of the plan.
• B. Widely spaced contour indicates flat surface.
• C. Closely spaced contour indicates steep slope ground.
• D. All of the above.

Answer 1

The correct option is D All of the above.

The characteristics of contour lines which help in plotting or reading a contour map are as follows;
1) Contour lines must close, not necessarily in the limits of the plan.
2) The horizontal distance between any two contour lines indicates the amount of slope and varies inversely on the amount of slope.
3) Widely spaced contour indicates a flat surface.
4) Closely spaced contour indicates a steep slope ground.
