Sandstone originates from the compaction and cementation of sand-sized mineral grains, primarily quartz or feldspar, which are often derived from the erosion of pre-existing rocks. Over time, these grains are transported by wind, water, or ice and deposited in various environments, such as riverbeds, deserts, or ocean floors. As layers accumulate, pressure from overlying materials causes the grains to bind together, forming sandstone. This sedimentary rock can then undergo further geological processes, leading to its eventual exposure at the Earth's surface.
