HOW DO THEY STACK UP?

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.

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

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).
