into a sedimentary rock. Sedimentary rocks like sandstone, shale and limestone differ from other rocks in that they: 1. Are formed from layers of sediment built up over many years. 2. Are grains of sediment cemented together by various minerals. 3. May contain fossils remains of plants and animals that were caught up in the sediment. 4.
