1) How would you apply the 'principle of original horizontality' to the layers (strata) in Fig. (c) Will the cure mentioned in the article be effective against indoor pollution in developing countries? Discuss why or why not. Answered step-by-step Asked by BarristerSquirrelPerson20 1) How would you apply the 'principle of original horizontality' to. (a) According to the article, what is the cause of sick building syndrome and what are the advantages of this cure? (b) What other sources of indoor pollution contribute to sick building syndrome? Will ultraviolet light be effective against these sources? Suggest one additional control measure that would be effective against SBS. The principle of superposition and the principle of original horizontality were put forward by Nicolaus Steno, a Danish scientist, in his arguments in favor of the organic origin of. Installing the systems would be relatively cheap and could save companies millions by reducing rates of sickness. Scientists said the UVGI killed the bacteria and molds in ventilation systems. Muscular complaints also halved, according to the study. There were 40 percent fewer complaints about respiratory problems and a 30 percent reduction in people complaining of stuffy noses. The lights resulted in a 20 percent reduction in all symptoms. They installed UVGI (ultraviolet germicidal irradiation) in the ventilation systems of the buildings and compared reports of illness when the lights were turned on with sickness rates when they were off. (A) The principle of original horizontality (B) The principle of supererogation (C) The principle of lateral continuity (D) The principle of fossil. ![]() Researchers from the Montreal Chest Institute in Canada tested three offices in the city where people suffered from SBS. ![]() ![]() Principle of Cross-Cutting Relationships e. Bacteria can build up in the ventilation systems and leave office workers suffering from a range of problems, such as breathing difficulties, headaches, sore throats, stuffy noses and itchy eyes. What principles did you use to determine the relative ages of the rock units (Select all that apply.) a. So-called sick building syndrome (SBS) is caused by the in creasing use of air conditioning in modern offices. Ultraviolet light in ventilation system cures sick building syndrome. The following appeared in Medical News Today on November 28, 2003. Where calculations are required, show your work. Support your answers with relevant information and examples. Available online.Write your answer to each part clearly. Layered rocks are generally laid down flat at their formation. In: M Hall, ed., 52 Things You Should Know About Geology. Principle of Original Horizontality « Back to Glossary Index. Review: Stratigraphy, Meta-Stratigraphy, and Chaos. Original Horizontality - States that sedimentary rocks are originally deposited in flat horizontal layers and then may later be tilted by faults and folding. And you just have to look at some seismic reflection data from the continental shelf to appreciate that this principle applies to even an outwardly rather continuous environment (excerpt of a line in the Virtual Seismic Atlas):īailey, R (1998). In it, he refers to Bailey (1998), who described sedimentary bodies as 'lenticles' with complex 3D geometries. Law of Superposition, Principles of Original Horizontality. Geology (edited by me, 2014) - see the link below. NOTE:A fracture is a crack A & B CROSS-CUTTING C & D CROSS-CUTTING D & E. Brian Romans wrote a nice essay on this subject in 52 Things. Why is the POOH dodgy? On small and large scales, the concept of 'layer-cake' stratigraphy does not hold up. with some caveats due to resedimentation and other processes. That law is, in a general sense, a foundation stone (ha!) of stratigraphy. It is not a useful theory.ĭon't confuse it with the law of superposition (also due to Steno), which is useful. No, Steno's principle of original horizontality (I'll call it the POOH) is not 'safe'. 1 Answer Sorted by: 8 No, Stenos principle of original horizontality (Ill call it the POOH) is not safe.
