What are some examples of sedimentary rocks?
Some common examples of sedimentary rocks are sandstone, limestone, shale, and conglomerate. Sandstone is formed from sand-sized grains of mineral, rock, or organic material, while limestone is made from the buildup of skeletal fragments of marine organisms. Shale, on the other hand, is formed from the accumulation of clay-sized minerals, and conglomerate is composed of rounded rock fragments that have been cemented together.
