Name ________________________________________ Date __________________ Class _______ Benchmark 3 Science Study Guide Geology 1. 2. 3. 4. S6E5 A-Crust, Mantle, Core What happens to the temperature as you travel to the center of the Earth? The temp increases or gets hotter What happens to the density as you travel to the center of the Earth? The density increases Put the layers of Earth’s interior in order from highest to lowest temperature. Inner core, outer core, mantle, crust The thickest layer of Earth’s interior is the mantle ; the thinnest layer is the crust. 5. What is the composition of each layer? Continental Crust: granite Outer Core: iron and nickel Oceanic Crust: basalt Inner Core: mostly iron, some nickel Mantle: iron, magnesium, hot rock 6. What mechanical layer is composed of the crust and upper mantle? lithosphere 7. What mechanical layer does the lithosphere ride/move on top of? asthenosphere 8. Why do lithospheric plates constantly move? because of heat and convection currents in the mantle 9. Why is the inner core solid? Because of the pressure 10. Label the layers of Earth’s Interior. S6E5 A 2 1 4 3 1. Crust 2. Inner core 3. Mantle 11. Identify the bar for each layer of Earth’s interior. A= crust B= mantle C= inner core D= outer core 4. Outer core Name ________________________________________ Date __________________ Class _______ S6E5e/f Lithospheric Plate Movement/Geologic features 12. Name the plate movement associated with each picture below a. b. divergent c. convergent convergent with subduction d. transform 13. What geological features are created at convergent boundaries? Mountains (2 continental plates), trenches (oceanic and oceanic plate), volcanoes (continental and oceanic plate) 14. What geological features are created at divergent boundaries? Sea floor spreading- makes mid ocean ridges (2 oceanic plates dividing) Rift valley (2 continental plates dividing) 15. What geological event takes place at transform boundaries? Major earthquakes 16. What geological features are created at convergent boundaries with subduction? Volcanic islands, volcanoes, trenches 17. What causes plate tectonic movement? Convection currents and heat 18. What are plates that move beneath another plate called? Why does this occur? Subduction… it happens because one plate is more dense than the other plate. 19. What is the Theory of Continental Drift? Who is responsible for this theory? All the continents were once all together and then they drifted apart and Alfred Wegner is responsible for this theory. 20. List 3 examples of evidence that supported Continental Drift Theory. Fossils, climate change, rocks, the shape of the continents. Name ________________________________________ Date __________________ Class _______ S6E5g Fossils 21. What is the law of superposition? Fossils and rock layers are older at the bottom and younger at the top layers 22. What are 2 examples of fossil evidence that supports climate change? The warm weather fern (Glossopteris) fossil was found on Antarctica. Australia use to be in the arctic regions, now it is closer to the equator. 23. What are 2 examples of fossil evidence that supports the changing of Earth’s surface? The fresh water reptile (Mesosaurus) and the same rocks were found on different continents, AND Providence Canyon was once under water. 24. Layers of soil 25. Soil Conservation Methods – Write the soil conservation type & definition from the cards you matched with the picture. Type: Contour Farming Definition: Planting crops along curves of land Type: Terracing Definition: Step-like structures on hill sides Name ________________________________________ Date __________________ Class _______ Type: No-till farming Type: Windbreaks Definition: Definition: Minimal plowing of land Planting tall trees around farm land to slow wind
