Document Summary
Introduction to geology: types of fossils, body fossilized body parts, trace record movement, tracks, impression fossils type of body fossil, how does something become a fossil, upon death, two things can happen: Strata a stratum is a layer of sedimentary rock or soil with characteristics that distinguish it from other layers. Stratigraphy study of rock layers and layering (stratification: two subfields, litostratigraphy, studying the strata, rock, sedimentation, rate of sedimentation determined by. Unstable state stable state = decay: if we know, amount of original parent isotope at the moment when animal died or rock formed, how much parent isotope is left. Basically we look at a sample and look at the ration or parent and daughter isotopes: rate of decay, dating, different isotopes have different rates of decay, half-life. Dinosaurs: 238 u, 235 u, 40 k, where can you find isotopes, not on dinosaur bone, igneous rock lava cools. 1/19/2016 5:21:00 pm quiz is lectures and 1, 2, 14.
