<p> Chapter 7 Study Guide Plate Tectonics</p><p>What is the major evidence that sea-floor spreading creates new lithosphere? Explain your answer.</p><p>If scientists were able to drill through the Earth’s crust, would it be better to drill through oceanic crust or continental crust? Explain your answer.</p><p>Tectonic plates forming a transform boundary may move only a few centimeters each year. Can even this small movement affect people and communities living near a transform boundary? Explain your answer.</p><p>Explain how folded mountain ranges form. </p><p>How does the position of a hanging wall relative to the footwall give evidence of the stress placed on a rock layer?</p><p>Describe the role of the asthenosphere in the movement of tectonic plates.</p><p>Describe, in detail how Pangaea broke apart. What were the pieces called? How do they relate to the modern names of the continents?</p><p>Describe the process that occurs at mid-ocean ridges. </p><p>Why is the mantle more dense that the crust? </p><p>Describe the components that make up the core (inner and outer) of the Earth. </p><p>Explain the theory of continental drift in your own words. What evidence do we have that actually proves that the theory was accurate? </p><p>Describe the components that make up the mantle in detail. </p><p>Describe the asthenosphere. What floats on the asthenosphere?</p><p>Explain the theory of plate tectonics in your own words. What evidence do we have to support Plate Tectonics?</p><p>Explain the difference between uplift and subsidence. </p><p>Explain how seismic waves travel through the Earth’s layers. Why do they travel at different speeds?</p><p>Describe a volcanic mountain. </p><p>Compare a fault block mountain range to a folded mountain range. </p><p>What forms when two tectonic plates are pulling away from each other? </p>
