By the law of original horizontality, each layer is younger than all the layers beneath it. Differences in sediment composition resulting from different sources, and variation in sediment brought about by change in agents of deposition, also lead to stratification. Some likely causes: grain size organic-matter content carbonate content. How does the medical condition of a person with endocrine dysfunction affect his or her way of life?, what will happen to a person with excessive secretion of growth hormones from the pituitary gland?, why is there a noticeable swelling in the front part of the neck of a person who has goiter?. Sedimentary rocks are made of different layers. These are cross-bedding, which is common in fluvial or eolian deposits, and graded bedding, which reflects transport by density (or turbidity) currents or, in certain cases, varved deposits. This happens in the formation of the Earth itself, rock layers, and water layers. In the middle of the rock layers. The layers of the Earth as a whole were formed by density. Solar radiation can only penetrate to 200 meters so water below this depth is very cold. The Principle of Original Horizontality. Their recognition and application are key to defining depositional . Density differences can be caused by differences in temperature or, in the case of the ocean, differences in salinity. However, water in all its forms is erosional. A classification of cross-stratification is suggested, based primarily on whether the lower bounding surface of a set of cross-strata is one of erosion or nondeposition and, if erosional, whether it is plane or curved. Both of these types of rocks are made primarily of silicon and some lighter metals like aluminum and magnesium.
