This image presents a matching exercise related to topographic maps and landforms. The task is to match the contour map on the left (labeled 1-4) with its corresponding 3D profile on the right (labeled a-d).
Let me solve this by analyzing each pair.
Step 1: Analyze Contour Map 1
- This map shows concentric, oval-shaped contour lines.
- The lines are closest together in the center, indicating a steep slope, and spread out towards the edges, indicating a gentler slope.
- This represents a single, symmetrical hill or mountain.
- Looking at the profiles,
c shows a single, smooth, conical peak, which matches this description.
Step 2: Analyze Contour Map 2
- This map has an elongated, oval shape with contour lines that are closer together on one side and farther apart on the other.
- This suggests a ridge or a hill that slopes more steeply on one side than the other.
- Profile
d shows a low, gentle slope rising to a rounded peak, which fits the description of a single, asymmetrical hill.
Step 3: Analyze Contour Map 3
- This map clearly shows two distinct sets of concentric contour lines.
- This represents two separate hills or peaks.
- Profile
b shows two distinct peaks separated by a valley, which is a perfect match for this contour map.
Step 4: Analyze Contour Map 4
- This map shows an elongated shape with two small, isolated contour lines inside a larger one.
- This represents a long ridge with two smaller bumps or knobs along its length.
- Profile
a shows a long, undulating ridge with two prominent peaks, which corresponds to this contour map.

Based on this analysis, the correct matches are:
*
1 matches with c
*
2 matches with d
*
3 matches with b
*
4 matches with a
The solution is:
1-c, 2-d, 3-b, 4-a
