It forms by
Mechanically formed sedimentary rock , Chemically formed sedimentary rock and Organically formed sedimentary rock.
Sedimentary rock can be formed from lithified sediments.
Sedimentary rock formed from sand is called sandstone.
Sedimentary rocks formed from the remains of plants and animals are called organic sedimentary rocks. Examples include coal, formed from the remains of plants, and limestone, formed from the shells of marine organisms.
Sedimentary rock, like limestone, is formed in layers.
Sedimentary rock.
The main types of sedimentary rocks are clastic (formed from fragments of other rocks), chemical (formed from minerals precipitated from water), and organic (formed from the remains of once-living organisms). Examples include sandstone, limestone, and shale.
sedimentary rock
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
Clastic and nonclastic
Clastic sedimentary rocks: Formed from the accumulation of mineral and rock fragments that are cemented together. Chemical sedimentary rocks: Formed from precipitation of minerals dissolved in water. Organic sedimentary rocks: Formed from the accumulation of organic material, such as plants or animals.
Sandstone rocks are formed from sedimentary rocks. It is when sedimentary rocks are broke down into small pieces.
