What does a contour line represent?
A
Points with same slope B
Points with same horizontal distance C
Points with same elevation D
Points with same direction
Analysis & Theory
A contour line connects points of equal elevation.
What does it mean when contour lines are very close together?
A
Flat ground B
Steep slope C
Gentle slope D
Water body
Analysis & Theory
Close contour lines indicate a steep slope.
Which method of contouring is faster but less accurate?
A
Direct method B
Indirect method C
Arbitrary method D
Interpolation method
Analysis & Theory
The indirect method is faster but requires interpolation.
What is the vertical distance between contour lines called?
A
Horizontal equivalent B
Contour slope C
Contour interval D
Contour distance
Analysis & Theory
Contour interval is the vertical difference between two lines.
A set of closed contours with decreasing elevation toward the center represents:
A
Hill B
Valley C
Depression D
Ridge
Analysis & Theory
Decreasing contour values in closed loops show a depression.
