Correct Option: C. Concave slope Detailed Explanation:

1. Understanding the Terms:
2. Ridge: A ridge is a long, narrow elevated landform, typically characterized by steep slopes on either side. It usually appears as a high point on a topographic map.
3. Scarp: A scarp is a steep slope or cliff that separates two relatively level areas of differing elevations. It often indicates a geological fault or erosion.
4. Concave Slope: A concave slope curves inward, resembling a bowl shape. It is characterized by a gradual decrease in elevation, where the slope is steeper at the top and becomes gentler towards the bottom.
5. Convex Slope: A convex slope curves outward, resembling a dome shape. It is characterized by a gradual increase in elevation, where the slope is gentler at the top and becomes steeper towards the bottom.
6. Analyzing the Profile:
7. When a profile is drawn along a specific line (in this case, M-P east of Parko - Ego road), it represents the changes in elevation along that line.
8. If the profile shows a gradual decrease in elevation that starts steep and becomes less steep, it indicates a concave slope. This is because the slope is more pronounced at the top and flattens out as you move downwards.
9. Why Option C is Correct:
10. The description of the profile along M-P suggests that the slope is not uniform but rather changes in steepness. A concave slope is characterized by this very feature, where the steepness decreases as you move down the slope.
11. The visual representation of a concave slope would show a curve that dips inward, indicating that the land is sloping downwards but at a decreasing rate.
12. Why Other Options are Incorrect:
13. Option A (Ridge): A ridge would show a profile that is consistently high with steep slopes on both sides. If the profile were a ridge, we would expect to see a peak rather than a gradual decrease in elevation.
14. Option B (Scarp): A scarp would indicate a sudden drop in elevation, creating a steep cliff-like feature. The profile would not show a gradual slope but rather a sharp change in elevation, which is not the case here.
15. Option D (Convex Slope): A convex slope would show a profile that starts off gentle and becomes steeper as you move down. This is the opposite of what is described in the question, where the slope is steep at the top and flattens out.

Common Pitfalls:

• Students may confuse concave and convex slopes due to their similar names. Remember that concave slopes curve inward and have a steeper top that flattens out, while convex slopes curve outward and become steeper as you descend.
• Misinterpreting the profile can lead to incorrect conclusions about the type of slope. Always visualize or sketch the profile to better understand the changes in elevation.

Revision Summary:

• A concave slope curves inward and has a steep top that flattens out.
• A ridge has steep slopes on both sides and is consistently high.
• A scarp indicates a sudden drop in elevation, resembling a cliff.
• A convex slope curves outward and becomes steeper as you descend.

Understanding these concepts will help you accurately interpret topographic profiles and identify different landforms in geography.
