To determine which rock layer shows the greatest evidence of erosion, we generally look for features such as an uneven surface, the presence of soil or sediment deposits, or a lack of vegetation.
Since I don't have the diagram in front of me, I can offer general guidelines:
- If a layer appears uneven or has a worn-down profile, it may indicate significant erosion.
- If there are features like gullies, channels, or a layer that is missing (implying it was eroded away), that might suggest more erosion.
If you can describe the characteristics of layers A, B, C, and D, I can help you further identify which one shows the greatest evidence of erosion.
