Sediment Grain Size Chart for Rocks - ThoughtCo
See more on thoughtco.comSediments are classified by their method of erosion as either clastic or chemical. Chemical sediment is broken down through chemical weathering with transportation, a process known as corrosion, or without. That chemical sediment is then suspended in a solution until it precipitates. Think of what happens to a gl…Grain size - Geology is the Way
