DAY 1: GEOLOGIC COLUMN VOCABULARY Week 3 Mini Q on Thursday Week 3 Mini Test on Thursday Entire Earthquake (ALL 3 weeks worth of notes) Test on Friday!! 1. Palentology= the scientific study of fossils 2. Superposition=a principle that states younger soil lies above older soil 3. Geologic column=an arrangement of rock & soil layers in which the oldest rock & soil are at the bottom 4. Relative dating=any method used to determine whether an object or event is older or younger than other objects or events
