Sedimentary geology is the study of sedimentary rocks and the processes that form them. These rocks are created from the accumulation and compaction of mineral and organic particles over time. Common types of sedimentary rocks include sandstone, shale, and limestone, each formed under different environmental conditions. This branch of geology also examines how sediments are transported and deposited by natural forces like water, wind, and ice. Understanding sedimentary geology helps scientists reconstruct past environments and geological history, providing insights into the Earth's evolution and the development of natural resources such as coal and oil.
