A Look at the Scientific Evidence. Part 1. The Significance:. Lawrence . Badash. . Prof. Emeritus, U. CA, S.B.. “…4.5 billion years ago, the primal earth emerged from a spinning, turbulent cloud of gas, dust and planetoids that surrounded the new star. …On these figures for the age of the earth rest all of geology and evolution.”. How old is the Earth?. Evolutionists say – about 4.5 billion years ago. Young Earth Creationists say – a few thousand years old. The Candle Analogy. Present-day observations are not a good basis for determining earth’s age.. Nuclear Material. Half-Life. is the required for of a radioisotope’s nuclei to decay into its products.. For any radioisotope,. # of ½ lives. % Remaining. Relative Dating. To . determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition.. Geological “Clocks”. Geologic time determination is subdivided into 2 categories:. Relative Dating: simply determines whether or not an event occurs before or after another event (e.g. a granite dike is younger than the surrounding sandstone since it intrudes across the sandstone in an outcrop)..

Estimating age in the archaeological record is the primary focus of archaeological sciences. Being able to establish a timescale is what sets archaeologists apart from other disciplines. . However. , relative dating techniques are still fundamental to the discipline.. Section 12.1 Discovering earth’s history. Uniformitarianism – the idea that physical, chemical, and biological laws that operate today also operated in the past; the present is the key to the past.. Muhammad Al . Fredey. Abdullah .
