Multiple choice

With reference to contours used for mapping the terrain, consider the following statements :

  1. Contours are horizontal to the dip of the land and perpendicular to the direction in which the surface water runs.
  2. Steeper the slope, farther the contour.
  3. Contours bend up-stream while crossing a river.
  4. Contours do not show up minor relief features. which of the statements given above are correct ?

  1. 1,2 and 3

  2. 1,3 and 4

  3. 2,3 and 4

  4. 1,2 and 4

B Correct answer
Explanation

Contours are perpendicular to the direction of water flow. They bend upstream when crossing a river (V-shape pointing upstream). They are spaced closer together for steeper slopes, not farther. They generally do not show minor relief features unless the contour interval is very small.
