Document Summary

Multiple choice and short answer (similar to lecture questions) (short answers only one or two sentences max. Terrestrial vs. jovian planets (size, composition, density, and atmosphere) Maria vs. highlands and earths impact history. Make sure to review lasts class lecture slides. World was once believed that the earth was created on a monday. Metaconglomerate- the oldest rock on the earth (found in australia) Relative ages of different rocks on the planet (in the earths crust) They have remained the same since the beginning of time stratigraphy involves correlation: principal of uniformitarianism. Lithostratigraphy- involves the study of large scale patterns in the physical characteristic of strata, specifically rock type(lithology) Conformable contacts-in a contact between two rocks units is conformable no significant break in sedimentation has occurred and the geological record is complete. Unconformable contacts- a significant break has occurred in the sedimentation to non deposit or erosion. Angular-rocks formed and are tilted and eroded new sedimentary rocks are laid on top.
