Sedimentary Rocks: Sediments

Sedimentary rocks are composed of sediments, which include small particles of loose rock, minerals, and organic remains. These rocks form when sediments are pressed and cemented together or precipitate from a solution. Sediments originate from various sources, such as sand on beaches, which are tiny rock pieces scattered by natural forces like wind, water, and ice. Dead animal remains, like shells, also contribute to sediment formation. Erosion plays a key role in moving sediments, which can eventually form sedimentary rocks.
