In general, it is best developed in fine-grained sediments and is least apparent and least persistent in coarse-grained materials such as conglomerates. In each of these locations, layer placement and the law of original horizontality can help scientists assign a relative age to each layer. What is the Law of Superposition? First, sedimentary rock can be formed when streams or rivers move sediment from one place to another. The top layer of water is warm and comfortable to swim in. The Principle of Original Horizontality. Stratification means arranging something, or something that has been arranged, into categories. Commonly, lamination is virtually invisible on fresh surfaces of sedimentary rocks but become apparent upon slight to moderate weathering of the surface. They are horizontal where deposition of sediments take place as flat-lying layers, and they exhibit inclination where the depositional site is a sloping surface. The same pattern of sedimentary rock could be expected to form and evidence of the event would reside in the stratified layers. Stratification is caused by sedimentary and igneous rocks that form layers. Answer: Water and wind sort sediments according to size, weight, and shape of particles, and these sediments settle in layers of relative homogeneity.
