Sedimentary rocks. Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified â turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas.
Sedimentary rocks are formed from grains of minerals and rocks, dissolved minerals and other material, such as plant matter or animal remains, which have been transported and deposited as sediment.lant material can be found as fragments in sandstones or other sedimentary rocks, and if it makes up the bulk of the rock it is termed coal. The shells of many marine organisms are made of calcium carbonate, and form limestone or calcite-rich sediments such as marl (a calcareous mudstone).
