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 25 m intervals in this plot. If in a flood, the water level rises to 525 m, which of the villages P, Q, R, S, T get submerged?
Correct answer
(C) R, S, T
Solution
Contour lines join points of equal elevation and here successive lines differ by . The labelled lines are , , and , and the levels of the unlabelled lines follow by counting in steps. A flood level of submerges every village lying below .
- P is inside the innermost closed loop of the left hill, which lies inside the loop. So P is above (in fact above ): not submerged.
- Q: on the right hill, going inwards from the line, the next line is , then the loop labelled , then a loop. Q lies inside the line but outside the loop, so its elevation is between and : not submerged.
- R lies in the saddle between the two hills, outside the contours of both hills, so it is below : submerged.
- S lies in the small closed pocket below the line whose inner loop is labelled . It is a depression, so S is below : submerged.
- T lies between the line and the line on the lower flank of the right hill, so its elevation is between and : submerged.
