<p>Map #1: Geologic Map (overhead) of Georgia and Alabama</p><p>Map #2: cross-section of Georgia and Alabama Geologic Maps and Cross Sections</p><p>1. Read the legend. What kinds of sedimentary rocks are shown in the maps?</p><p>2. What environment do you think was present during the deposition of the rocks in this area?</p><p>3. Compare the thickness (vertical extent) on the cross-section (Map #2) to the distance covered (lateral extent) on the overview (Map #1).</p><p>4. Sedimentary rocks are originally deposited in flat, horizontal layers. Given this fact, why do you think that some of the layers in the cross-section are tilted?</p><p>5. On the cross-section, follow the units named Eutaw and Tuscaloosa (green layers). Are the units continuous? Why or why not?</p><p>6. What kinds of igneous rocks are shown on the maps? 7. Are the igneous rocks intrusive or extrusive? How do you know?</p><p>8. Compare map #1 and map #2. Are the igneous rocks you see in the cross-section visible on the map? Why or why not?</p><p>9. Compare the rock units labeled Pinckneyville Granite, Paleozoic Granite and Jurassic-Triassic Intrusives. How do their sizes vary?</p><p>10. Look at the Paleozoic Granite, and the Jurassic-Triassic Instrusives. How are they different? How are they similar? How do they differ from the Pinckneyville Granite?</p><p>11. What kinds of metamorphic rocks are shown in the maps?</p><p>12. How does the placement of the metamorphic rocks compare with the surrounding rock units?</p>
