Which of the following is a correct property of contour lines?
A
They cross each other B
They form triangles C
They always form closed loops D
They show temperature zones
Analysis & Theory
Contour lines form closed loops or extend to map boundaries.
What does a V-shape in contour lines pointing uphill represent?
A
A ridge B
A depression C
A valley D
A hill
Analysis & Theory
Contour V-shapes pointing uphill usually represent a valley.
Which method of contouring involves direct marking of contour points in the field?
A
Grid method B
Direct method C
Cross-section method D
Indirect method
Analysis & Theory
Direct method involves identifying and marking contour points directly.
Which method of contouring is faster but less accurate?
A
Direct method B
Grid method C
Indirect method D
Trigonometric method
Analysis & Theory
Indirect method uses interpolation and is faster, though less precise.
In uniformly sloped terrain, contour lines are:
A
Randomly spaced B
Evenly spaced C
Very close together D
Missing
Analysis & Theory
Uniform slope leads to evenly spaced contour lines.
