361. Contour lines on a topographic map represent:
a) Roads and highways
b) Rivers and lakes
c) Points of equal elevation
d) Vegetation types
View Answer
Correct answer: c) Points of equal elevation
Explanation: Contour lines connect points of the same elevation on a map, allowing us to visualize the shape of the terrain.
362. The contour interval on a map represents:
a) The distance between contour lines
b) The elevation difference between adjacent contour lines
c) The width of a contour line
d) The direction of water flow
View Answer
Correct answer: b) The elevation difference between adjacent contour lines
Explanation: The contour interval indicates the vertical distance between adjacent contour lines on a map, providing information about changes in elevation.
363. Contour lines that are close together represent:
a) Steep slopes
b) Gentle slopes
c) Flat areas
d) Valleys
View Answer
Correct answer: a) Steep slopes
Explanation: When contour lines are closely spaced, it indicates a steep slope or change in elevation.
364. Contour lines that are far apart represent:
a) Steep slopes
b) Gentle slopes
c) Flat areas
d) Plateaus
View Answer
Correct answer: b) Gentle slopes
Explanation: Widely spaced contour lines indicate a gentle slope or gradual change in elevation.
365. On a topographic map, a V-shaped contour pattern represents:
a) A ridge or hilltop
b) A valley or depression
c) Flat terrain
d) A river or stream
View Answer
Correct answer: b) A valley or depression
Explanation: A V-shaped contour pattern with the apex pointing upstream represents a valley or depression.
366. The direction of water flow on a topographic map is indicated by:
a) Contour lines crossing rivers
b) Contour lines pointing uphill
c) Contour lines bending downstream
d) Contour lines parallel to each other
View Answer
Correct answer: c) Contour lines bending downstream
Explanation: Contour lines that bend or curve in the direction of water flow indicate the path of rivers or streams.
367. Contour lines that form closed loops represent:
a) Hilltops or ridges
b) Valleys or depressions
c) Plateaus or flat areas
d) Water bodies
View Answer
Correct answer: b) Valleys or depressions
Explanation: Closed contour loops with higher elevation values inside represent valleys or depressions.
368. Which of the following is true about contour lines crossing streams or rivers on a map?
a) Contour lines converge upstream
b) Contour lines diverge downstream
c) Contour lines are perpendicular to the flow
d) Contour lines follow the flow direction
View Answer
Correct answer: b) Contour lines diverge downstream
Explanation: Contour lines that cross streams or rivers diverge downstream, indicating a decrease in elevation.
369. The index contour on a topographic map is:
a) A contour line labeled with elevation values
b) The contour line with the highest elevation
c) The contour line with the lowest elevation
d) The contour line with the steepest slope
View Answer
Correct answer: a) A contour line labeled with elevation values
Explanation: The index contour is typically a darker or thicker line on a map and is labeled with elevation values to provide reference points.
370. Which of the following statements is true about contour lines that form concentric circles?
a) They represent cliffs or steep slopes
b) They indicate a plateau or flat area
c) They indicate the path of a river or stream
d) They represent areas of dense vegetation
View Answer
Correct answer: b) They indicate a plateau or flat area
Explanation: Contour lines forming concentric circles represent a plateau or flat area with no significant changes in elevation.
