Poorly Sorted Sediment

Sedimentary Rocks

Sedimentary rocks can be classified as either clastic sedimentary rocks or chemical sedimentary rocks. Clastic sedimentary rocks are those rocks formed from the lithification of sediment derived from the weathering and erosion of other rocks and material. Since the movement and final deposition of this sediment is dependant on the environmental and climatic aspects of a geographic region, understanding how these factors influence the composition of sediment and therefore the resulting rock gives us great insight into the climate and environmental condition of the past.
