Sedimentary rocks are formed from plant and animal remains or weathered and eroded particles from rocks. Transported by water or wind, they are forming layers which turn into so called sediments. As they are buried under new layers of sediment, they are compacted by pressure and heat eventually turning into sedimentary rock. This process happens over millions of years.
