Sedimentary rocks are made of particles that result from weathering and erosion of pre-existing rocks. These particles, such as sand, silt, and clay, are carried by water, wind, or ice and accumulate in layers, eventually forming sedimentary rocks through compaction and cementation processes.
This process is known as the rock cycle. It involves the formation, breakdown, and reformation of rocks through various geological processes such as erosion, deposition, heat, and pressure. Rocks can transform from one type to another, such as sedimentary to metamorphic or igneous to metamorphic.
