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
Read the contour values crossed along the dashed path.
1.P lies inside the innermost closed contour of the left hill (above ), i.e. near its summit.
2.Moving away from P the path crosses the and contours outward and reaches the saddle/valley near the contour: Down.
3.It then climbs the right hill, crossing , and entering the closed contour: Up.
4.Finally it leaves the contour to reach Q, which lies outside that loop: Down.
So the path is Down-Up-Down. Options A and D start with "Up", which is impossible from a summit, and B ends with an extra "Up".Answer: (C) Down-Up-DownContinue learning with Success Tracker
