  1. DO NOW • Pick up test study guide. • Turn in Vocabulary if you have not. • Get out four sheets of notes for unit 7. • Article Summary #7 due Friday. • Missing Article Summary #6 and the day you said you would turn it in • February 7: Tyson, Edgar, Priscilla • February 8: Anna, Hayden, Bethany, Shamya

  6. HOW DO THEY STACK UP?

  7. What Did They Tell You? What does the order tell you: Law of Superposition – order environments occurred – notice that layers 1-4 show that the environment had decreasing energy of deposition as the ocean took over land. Why do the layers slope: Uplifting occurred at some point – folding – convergent plate movement. Why are there missing sections of rock: Erosion wore away some of the rock.

  12. Unit 7 Review What to expect, what to know…

  13. Standards SES4. Students will understand how rock relationships and fossils are used to reconstruct the Earth’s past. • a. Describe and apply principles of relative age (superposition, original horizontality, cross-cutting relations, and original lateral continuity) and describe how unconformities form. • b. Interpret the geologic history of a succession of rocks and unconformities. • c. Apply the principle of uniformitarianism to relate sedimentary rock associations and their fossils to the environments in which the rocks were deposited. • d. Explain how sedimentary rock units are correlated within and across regions by a variety of methods (e.g., geologic map relationships, the principle of fossil succession, radiometric dating, and paleomagnetism). • e. Use geologic maps and stratigraphic relationships to interpret major events in Earth history (e.g., mass extinction, major climatic change, tectonic events).

  14. REVIEW

  15. REVIEW • Several terms to know: • Law of Superposition • Principle of Original Horizontality • Principle of Uniformitarianism • Law of Cross Cutting Relationships • Principle of Lateral Continuity • Unconformities

  16. REVIEW • Oldest is on the bottom. • Youngest is on the top.

  17. REVIEW Gravity causes sediments to be laid flat.

  18. REVIEW The way it happened in the past is the way it happens now.

  19. REVIEW If it cuts through a layer, it is younger than the layer.

  20. REVIEW Layers of sediment spread outward.

  26. REVIEW Rock cooked by magma is younger than the rock it is in.
