Sandstone is a type of sedimentary rock made up of tiny grains of sand that have been cemented together over time. It often forms in layers, usually in environments like riverbeds, beaches, or deserts. The colors of sandstone can vary widely, ranging from tan and yellow to red and brown, depending on the minerals present in the sand. This rock is commonly used in construction and landscaping due to its durability and attractive appearance. Famous structures, such as the Sydney Opera House and the Red Rock Canyon, showcase the beauty of sandstone. Its natural texture and colors make it a popular choice for both indoor and outdoor projects.
