Erosion is one way that scientists could try to determine if the Rocks are residual (from the area) or transported from far away
Step-by-step explanation:
Erosion is the process in which the waste or broken parts of the rocks are taken or transported from one place and deposited on the other place. This process takes place through air, water or ice.
Scientists study the process of erosion in-depth to determine the movement of sediments from one place to another. After erosion immediately deposition takes place. Whatever is eroded has to be deposited somewhere. Erosion always takes place on the surface of the earth.
