1. Residual Soil: This refers to soil that remains in place after the original rock has been weathered and eroded. It is often found in areas with a high concentration of clay and other fine particles.
2. Relict Bedrock: This refers to bedrock that has been exposed by erosion. It is often surrounded by younger, more weathered rock formations.
3. Weathering Products: This is the general term for the minerals and rocks that are created when rocks are broken down by weathering processes. These products can include clay, sand, and even dissolved minerals.
4. Residual Deposits: This refers to any mineral deposits that are left behind after the original rock has been removed by weathering or erosion. Examples include bauxite deposits, which are formed from the weathering of aluminum-rich rocks.
