Explain how the size, shape, and sorting of sediments can provide information about the distance the sediment has traveled from its source

What will be an ideal response?


Answer: When sediments are first weathered from their source rock, they are angular and poorly sorted and consist of a variety of sizes. However, as they travel, they impact against each other or against bedrock, a process that rounds down the sharp corners and wears down the sediment size. Sediments that are finer, well rounded, and well sorted indicate that the sediments have traveled a long way from the source.
