How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles. Clastic sedimentary rocks, fascinating components of the Earth’s crust, are formed by the aggregation of ‘clasts’—fragments of other rocks and minerals. These clasts can vary in size from minuscule grains of sand to enormous boulders, their movement and eventual placement dictated by the forces of water, wind, ice, and gravity.19 Examples of metamorphic rocks. With all we have talked about metamorphic rocks, it is time to go to the various examples and say a thing or two. 1. Slate.
