Sedimentary rocks are formed through the accumulation and compression of sediments over time. These rocks are made up of particles of minerals, rocks, and organic materials that have been weathered and transported by wind, water, or ice. The sediments settle in layers, creating distinct strata within the rocks. Over millions of years, the weight of the overlying sediments compresses the layers below, resulting in the formation of solid sedimentary rocks. Examples of sedimentary rocks include sandstone, limestone, and shale. These rocks often contain fossils and provide valuable insights into Earth's history and the past environments in which they formed.
