Difficulty: EasyContour Lines and Relief Representation

On a topographical map, a series of V-shaped contour lines have their apexes (pointed ends) pointing towards higher elevation. Which of the following relief features is represented by this contour pattern?

  1. A river valleyAnswer
  2. B
    A mountain spur
  3. C
    A plateau
  4. D
    A conical hill

Answer

A river valley
When contour lines cross a river or valley, they bend upstream into a V-shape. Because the river flows from higher to lower ground, the V-shape points toward higher elevation (upstream). Therefore, V-shaped contours pointing toward higher ground represent a river valley.

Step-by-Step Solution

1
Examine the shape and orientation of the contour lines.
The contour lines form V-shapes pointing toward higher elevation.
Water flows downhill, so river valleys cut into higher land, causing contour lines to bend upstream (towards higher elevation) where they cross a stream.
2
Identify the corresponding topographic landform.
V-shaped contours pointing uphill represent a river valley or ravine.
The apex of the 'V' points up the valley toward the river source.
