Question
A contour line joins locations having the same height above the mean sea level. The following is a contour plot of a geographical region. Contour lines are shown at intervals in this plot.
The path from P to Q is best described by
Correct answer
(C) Down-Up-Down
Solution
To determine the nature of the path from P to Q, we observe the values of the contour lines crossed:
1.Starting at P: Point P is located inside the contour line, indicating a peak or high elevation area ().
2.First Segment: Moving towards Q, the path crosses the line, then the line, and enters the region enclosed by the line. This indicates a descent (Down).
3.Second Segment: The path then leaves the region, crosses the line, and enters another contour region. This indicates an ascent (Up).
4.Third Segment: Finally, the path leaves the region and moves towards point Q, which is located near the contour line. This indicates a final descent (Down).
Thus, the sequence of elevation change is Down-Up-Down.Continue learning with Success Tracker
