GEO 102: STUDY QUESTIONS FOR TEST I (Be sure to use the questions at the end of each chapter as well as the online resources and quizzes in each chapter): Introduction Sketch and label a pie-shaped cross section of the Earth Name 3 energy sources for the early differentiation of Earth. What are Earth's Internal and External Processes; energy sources for these? List the four eras of the geologic time scale, oldest at bottom, youngest at top. How fast do plates move? If 2 plates move apart at 10 cm/year, how long would it take for them to move 1 km?150km? Plate Tectonics -What was the pre-1960s evidence for continental drift? Why was it not generally believed? -What was Pangaea? -What is paleomagnetism? In what two ways did it help support the plate tectonics hypothesis? -What is sea-floor spreading? Who formulated the concept? -How were plate boundaries first defined? -How does plate tectonics theory help explain continental drift? -Why can oceanic crust be subducted but continental crust not? -Why must production and destruction of lithosphere be approximately balanced? -With which type of plate boundary is each associated? Himalayas. Aleutians, Red Sea, Andes, San Andreas fault, Iceland, Japan, Mt. St. Helens. -A transform fault connecting a left-lateral offset in a mid-ocean ridge will (a) be active only in the segment between the ridges (b) generate deep-focus earthquakes (c) slip in a left-lateral direction (d) show normal faulting (e) a and c above. (Be careful!!!) -The most favored (but still incomplete) theory to explain the driving forces in plate tectonics concerns: (a) geosynclines (b) tidal forces (c) convection currents in the core (d) slow convective movements in the mantle (e) antigravity.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
