Sandstone

Sandstone is a type of sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. It forms when these particles are compacted and cemented together over time, often in riverbeds, beaches, or deserts. Sandstone can come in various colors, depending on its mineral content, and is widely used in construction and artwork due to its durability and aesthetic appeal. Notable for its layered appearance, sandstone can also hold fossilized remains, which make it important for studying Earth's history. Its porosity allows it to store water, making it significant in hydrogeology as well.
