Document Summary
Geologic time and stratigraphy (sub science of geology where rocks are placed in order-study of layers-relative age of rocks). Now, absolute ages can be determined with high precision. Need to be able to establish order of event. Law of superposition-younger rocks occur on older ones. 4. 56 billion years (4, 560, 000 years old) One of the big problems of geology: rocks get folded, bent and broken. Margins of north america: rocks are folded in complex ways. Geologic timescale: starts at 0 (4. 56 billion years)- broken up into geologic periods. Ancient greeeks recognized fossils embedded in rocks now on tops of mountains. Sediments get deposited on top of older sediments. Many rocks contain fossils, once existedin marine but now exist in mountains. First view of stratigraphy in the bible. Strict biblical interpretation of earth"s history (rocks and landscapes result from. More than one flood recognized (new life created each time so each layer contains different life forms)
