To accurately determine the rock type based on weathering patterns, I would typically need to know more details about the specific characteristics of the weathering you observe, as different rocks weather in distinctive ways. However, I can provide some general guidance based on common weathering patterns associated with each type of rock:
- **Granite** (A): Weathering typically leads to the formation of clay minerals and quartz sand, often showing relatively large grains and a tendency to break along mineral lines.
- **Sandstone** (B): Tends to weather into smaller grains of sand; it can break down more uniformly across the surface, maintaining a sandy appearance.
- **Limestone** (C): Often weathers by dissolution, leading to features like sinkholes or rounded shapes, and may display more smooth surfaces due to chemical weathering.
- **Shale** (D): Weathering can cause it to split into thin layers or flakes; it may also lead to the development of soft, muddy textures.
If you are observing smooth, rounded surfaces and signs of dissolution, **C. Limestone** might be the correct answer. If you see layer separation and flaky textures, then **D. Shale** could be more appropriate. For a rugged texture with larger grains, it could be **A. Granite** or **B. Sandstone**.
Since I don’t have the specific weathering pattern you are referring to, I recommend using the descriptions above to match your observations with the characteristics of each rock type.
