Geology 112 Exam 1 Review Concepts Exam will cover material for the first part of the course. Exam format will be short answer style. You can answer the questions with an outline /short answer/sketch-concise answers and well-labeled sketches are best. Take a look at the outlines on the webpage as well as your notes and the readings from the book. Here is a list of the main topics we have covered thus far: Unconformities. What they are, what do they look like. Relative Age dating: Stratigraphic principles Absolute age dating: Half-life, geologically useful geologic isotopes, assumptions underlying the use of absolute age dating, what types of rocks are used. How isotopic dating is used to constrain the geologic time scale. Paleomagnetism: what types of rocks are used, what the basic premise is for using it as a dating tool, how it has been used to confirm sea floor spreading Time Scale: Know the eons and eras, numeric age boundaries between them. Currently accepted ages for the earth, oldest minerals, rocks, fossils Carbon Cycle: photosynthesis and respiration. Relationship between abundances of C and O and their isotopes Fossils: what are they and how are they preserved What are the main kingdoms of life Types of plate boundaries and the features associated with them Early history of the earth-oxygen free atmosphere, volcanic degassing to produce atm. and oceans. Greenstone belts and Granulite/Gneiss terranes: early differentiation of contintental crust.
