Zorluk: KolayContour Lines and Relief Representation

Match each contour line pattern description on the left with the correct relief landform or slope type it represents on the right.

  • V-shaped contours with the apex pointing toward higher elevationRiver valley
  • V-shaped contours with the apex pointing toward lower elevationSpur
  • Contours closely spaced near the top and widely spaced at the baseConcave slope
  • Contours widely spaced near the top and closely spaced at the baseConvex slope

Cevap

V-shaped contours pointing uphill match with River valley; V-shaped contours pointing downhill match with Spur; contours closely spaced near the top match with Concave slope; contours widely spaced near the top match with Convex slope.
V-shaped contours with their apex pointing uphill reflect a river valley, while those pointing downhill depict a spur. Slope profiles are determined by contour density: closely spaced lines near the summit combined with widely spaced lines at the base form a concave slope, whereas widely spaced lines near the summit combined with closely spaced lines at the base form a convex slope.

Adım Adım Çözüm

1
Determine the landform associated with V-shaped contour orientation
A 'V' shape pointing toward higher ground indicates a valley cut into the terrain by water flow, whereas a 'V' shape pointing toward lower ground represents a protruding ridge section (spur).
Water flows downhill, creating re-entrants that cut into higher land, while spurs project outward into lower land.
2
Analyze contour spacing relative to slope profile steepness
Tight spacing indicates a steep slope, while wide spacing indicates a gentle slope. Steep top with gentle base yields a concave slope; gentle top with steep base yields a convex slope.
Contour line density directly corresponds to gradient changes across relief features.
