Plastic remains in the oceans have recently attracted attention and are perceived as a serious problem.
You are asked to write a brief scientific assessment for the “Scientific Association for the Promotion of Rational Environmental Policy” on what measures at European level could most effectively limit further increase in pollution of the Mediterranean Sea.
xplain the importance of the following dating methods: (a) radio carbon dating, (b) potassium argon dating, (c) seriation, (d) stratigraphy. Archaeology can be defined as “the scientific study of the human past, of ancient human behaviour, from the earliest times right up to the present.”(Fagan, 2006) .The study of archaeology as an academic discipline is dependant on the accuracy of various dating methods. Dating methods in archaeology can be divided into two groups: Relative dating methods and Absolute dating methods. Although the importance of the different dating methods may outweigh each other, the all are very important to the study of archaeology as a whole. This essay shall focus on the importance of radio carbon dating, potassium argon dating, seriation and stratigraphy to the archaeological study. Accurate dating has always been of importance to scientist and archaeologist alike. In archaeology dating can be categorised into relative dating and absolute dating techniques. In moving forward explain the importance of radio carbon dating, potassium argon dating, seriation and stratigraphy to the archaeological study, one must first understand the difference between relative dating and absolute dating in archaeology. Relative dating in archaeology assumes the age of an artifact in relation and by comparison to other objects found in its environs. The style of the artifact and its archaeological location stratigraphically are required to arrive at a relative date. The limit to relative dating is that it cannot provide an accurate year or a specific date of use. Absolute dating on the other hand is the method of determining an approximate calculated age of an artifact in archaeology. The goal of archaeologist is ultimately to know how old sequences, sites and artefacts are in calendar years. To accomplish this absolute dating methods are used. From traditional historical methods to those which are based on the great variety of modern scientific techniques currently available. As compared to relative dating which only provides an order of events, absolute dating presents archaeologists with a more calculated evaluation of the object’s age. The first area of discussion in understanding the different dating techniques in archaeology would be stratigraphy. According to Renfrew and Bahn, “stratigraphy is the study of stratification- the laying down or depositing of strata one above the other.” (Renfrew and Bahn 2008, 122). This basically involves ordering things into sequences. A succession of layers should provide a relative chronological sequence from the earliest (the bottom layer) to the latest (top), as seen in figure one. It’s important to note that stratigraphy involves the Law of Superposition. Fag>GET ANSWER
