Zorluk: OrtaContour Lines and Relief Representation

Match each relief feature or slope type with the contour line pattern that uniquely describes its representation on a topographical map.

  • Concave SlopeContour lines are closely spaced at higher elevations and widely spaced at lower elevations
  • Convex SlopeContour lines are widely spaced at higher elevations and closely spaced at lower elevations
  • Col (Saddle)A low pass between two peaks bounded by contour lines curving away on opposing sides
  • Escarpment (Cliff)Contour lines merge or lie extremely close together along a steep vertical face

Cevap

Concave Slope pairs with closely spaced contours at higher elevations and widely spaced contours at lower elevations; Convex Slope pairs with widely spaced contours at higher elevations and closely spaced contours at lower elevations; Col (Saddle) pairs with a low pass between two peaks bounded by contour lines curving away on opposing sides; Escarpment (Cliff) pairs with contour lines merging along a steep vertical face.
The paired features match their exact cartographic representations: concave slopes are steeper at high elevations; convex slopes are steeper at low elevations; cols are pass features between summits; and escarpments display merged contours due to vertical cliffs.

Adım Adım Çözüm

1
Analyze the gradient changes of concave and convex slope profiles.
A concave slope grows steeper with altitude (contours close together near the top), while a convex slope flattens out near the top (contours widely spaced near the top).
Contour spacing directly corresponds to terrain gradient; closer contours indicate steeper slopes.
2
Identify the structural contour representation of a col or saddle.
A col appears as a low point between two adjacent high areas where contours loop away from the center gap.
The neck between two peaks creates a characteristic hourglass-shaped contour arrangement.
3
Examine how extreme vertical drops are shown on topographic maps.
A cliff or escarpment has very small or zero horizontal distance between elevation changes, making contour lines run together or merge.
Vertical relief over negligible horizontal equivalent results in overlapping contour lines.
