The exam will be worth 25% of your grade. It will consist of 50 multiple choice questions. Many questions may be variations on questions you’ve already had. Many will be brand new.
The exam will be cumulative, but will emphasize material from the second half of the quarter, especially that presented since the last quiz.
Earth chemistry and structure
Most common elements in crust and whole earth
Core, Mantle, Crust, Lithosphere, Asthenosphere
Rocks: Igneous, Metamorphic, Sedimentary, Rock Cycle
Magmas, chemistry and magma properties, lava, volcano types, style of eruptions, intrusive bodies
Plate Tectonics and Continental Drift
Type of plate margins, maps and plate tectonics, hot spots and their evolution, relation of plate tectonics to magmatism and mountain building. Evidence for Continental Drift; evidence for Plate Tectonics.
Shale to slate to phyllite to schist to gneiss: how these rocks differ and why.
Contact metamorphism vs. regional metamorphism
Types of sedimentary rocks
Environments of deposition and how the sediment compares to original bedrock source.
Geologic structures: faulting and folding
Ductile vs brittle deformation. Different types of stress and resulting structure. How faults differ from each other.
Geologic structures and maps
Difference in map appearance of horizontal vs. dipping beds.
Geologic history as determined from cross-sections
Geologic Contacts, sequence of events, unconformities
Geologic Time scale
Absolute vs. Relative time --and aspects of each.
Evidence for Deep Time
