... Start studying Stratigraphic Laws. Cross-cutting relationships is a principle of geology that states that the geologic feature which cuts another is the younger of the two features. The principal of original continuity states that, over any flat area, sediments are deposited relatively evenly. It is fundamental to geologic thinking and the science of geology. ... Geology Exam 3 31 Terms. Steno's laws of stratigraphy describe the patterns in which rock layers are deposited. Steno’s final principle is the “principle of lateral continuity,” which says that sediment layers spread out until they reach an obstacle that keeps them from spreading further, the way soup spreads out in a bowl until it reaches the sides of the dish. Law of Lateral Continuity. mparava. The four laws are the law of superposition, law of original horizontality, law of cross-cutting relationships, and law of lateral continuity. principle that states that sediments are deposited over a large area in a continuous layer that may be traced laterally; one of Steno's Laws. A simple way to think about this is that for something to be on top of something else, for example in order to put a book on top of a table, the table has to be there. principle that states that a geologic feature is older than the feature that does the cutting. Three of these are known as Steno's principles, and a fourth observation, on crystals, is known as Steno's Law. Cross-Cutting Relations. Psych Exam 2 32 Terms. It is a relative dating technique in geology. Lateral Continuity. strata extend laterally until they pinch out at the edge of the basin. • This principle is used to trace coal … law of cross-cutting relationships An igneous rock, fault, or other geologic feature must be younger than any rock across which it cuts. The principle of horizontal layering states that sediments are deposited in flat, nearly horizontal layers, so if layers of rock are inclined or folded, this occurred after they formed. Nicolaus Steno was a 17th-century Danish geologist. Nicolaus Steno, formulated a few basic rules that helped him make sense of the rocks, Principle of Initial Horizontality, Principle of Strata Continuity, Principle of Cross Cutting Relationships, The Principle of Superposition. The quotes given here are from the English … • Thus, matching strata on opposite sides of a valley can be correlated. This principle states that a sequence of rocks in their original orientation will have the oldest rock on the bottom and the youngest rock on the top. It was first developed by Danish geological pioneer Nicholas Steno in Dissertationis prodromus (1669) and later formulated by James Hutton in Theory of the Earth (1795) and embellished upon by … Learn vocabulary, terms, and more … https://www.thoughtco.com/stenos-laws-or-principles-1440787 An Undersea Mountain: Tectonic Plates and Hydrothermal Vents - Perspectives on Ocean Science - Duration: 46:12. Uniformitarianism, in geology, the doctrine suggesting that Earth’s geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity accounts for all geologic change.
