• Generally, rocks can be divided into three major types based on the process of their formation
• Igneous rocks are formed by the solidification and cooling of magma in volcanic areas, 
• While sedimentary rocks are formed by a low-temperature accumulation of sediments in tectonic basins and topographical sinks. 
• Metamorphic rocks on the other hand are formed by application of temperature and pressure on pre-existing rocks

The movement of goods was speeded up by the development of Railways. Maximum economies are typically realized with bulk commodities especially when hauled over long distances. However, shipment by rail is not as flexible as by highway, which has resulted in much freight being hauled by truck, even over long distances. Moving goods by rail often involves transshipment costs, particularly when the shipper or receiver lack direct rail access. These costs may exceed that of operating the train itself, a factor that practices such as containerization aim to minimize.
