Chapter 10: Representation of Relief Features and Climatic Data — Important Questions & Answers
What does a contour line represent on a topographic map?
- A. A line joining places of equal height above mean sea level
- B. A line joining places of equal rainfall
- C. A line joining places of equal temperature
- D. A line joining places of equal slope
Answer: A. A line joining places of equal height above mean sea level
A contour line connects points that have the same elevation above mean sea level. It is used to show relief features on a map.
A contour line connects points that have the same elevation above mean sea level. It is used to show relief features on a map.
The vertical distance between two consecutive contour lines is called:
- A. Contour interval
- B. Contour gradient
- C. Spot height
- D. Bench mark
Answer: A. Contour interval
Contour interval means the difference in height between adjacent contour lines. It is fixed for a given map.
Contour interval means the difference in height between adjacent contour lines. It is fixed for a given map.
When contour lines are very close to each other, the slope is generally:
- A. Gentle
- B. Flat
- C. Steep
- D. Depressed
Answer: C. Steep
Close contour spacing means the height changes rapidly over a short distance. This indicates a steep slope.
Close contour spacing means the height changes rapidly over a short distance. This indicates a steep slope.
Which statement best explains why contour lines never meet or cross each other on a normal topographic map?
- A. Each contour represents the same elevation, so crossing would mean one point has two heights
- B. Contours are drawn only for hills, not valleys
- C. Contours represent rainfall zones
- D. Contours are used only on political maps
Answer: A. Each contour represents the same elevation, so crossing would mean one point has two heights
A contour line joins points of equal elevation. If two contours crossed, a single point would have two different heights, which is impossible.

Which of the following is the most appropriate sequence for constructing a simple line profile from a contour map?
- A. Draw a line on the map, note contour intersections, transfer them to graph paper, and plot heights
- B. Calculate rainfall, draw a bar diagram, and then mark heights
- C. Measure latitude, then longitude, then draw contours
- D. Identify soil types, mark vegetation, and then sketch slope
Answer: A. Draw a line on the map, note contour intersections, transfer them to graph paper, and plot heights
A line profile is drawn by selecting a line, marking where it cuts contour lines, transferring the marks, and plotting elevations on graph paper. This produces the relief profile.
