Question

A line lying throughout the surface of the ground and preserving a constant inclination to the horizontal is

• A. \( \text{Contour gradient} \)
• B. \( \text{Horizontal equivalent} \)
• C. \( \text{Contour interval} \)
• D. \( \text{Vertical control} \)

Hint:

Think of contour gradient as a path going uphill or downhill at a steady rate.

Answer 1

The Correct Option is A

A contour gradient is a line laid out on the ground that maintains a constant slope or inclination with respect to the horizontal. A contour line connects points of equal elevation. Horizontal equivalent is the horizontal distance between two consecutive contour lines. Contour interval is the vertical distance between two consecutive contour lines. Vertical control refers to points of known elevation used for surveying.
