Professor FitzGerald Spring 2011
Introduction to Beaches and Shorelines ES 142
Exam #1 Study Questions
SUBJECT: Plate Tectonics 1. What occurs at subduction zones? Draw a cross section of oceanic plate subducting beneath a continental plate (Nazca beneath South America). 2. What is the lithosphere and what are the major lithospheric plates? 3. What are the various features and processes that define plate boundaries? 4. What processes occur at mid-ocean ridges and why? 5. What is a shear zone (transform)? 6. What is a hot spot (geologically speaking), what do they form in ocean basins, and what do they indicate about the Pacific plate (trend of Hawaiian Islands)? 7. What are oceanic and continental crust composed of? 8. What is the Asthenosphere and what properties does it have that enable plates to move across it and be subducted into it? 9. Give examples of Collision, Spreading, and Shear Zones. 10. What is an island arc? 11. What is rifting? Where has this process occurred in the recent geologic past (20 million yrs)? 12. What is suture zone? Give examples.
SUBJECT: Tectonic Coastal Classification 1. What is this classification based on (four factors)? 2. Describe the characteristics of a Collision Coast. 3. What are the different types of Trailing Edge Coasts and how do they differ from one another in tectonic setting and morphology? 4. Why are the continental shelf and coastal plain of Amero-trailing Edge Coasts flat and wide? 5. What process forms Neo-trailing Edge Coasts, give examples? 6. How did the Cascade Mountains form? 7. What happened during the 1964 Good Friday Earthquake along the Alaskan shore (Copper River Delta barriers)? 8. Define a Marginal Sea Coast, give examples.
SUBJECT: Sediment Supply 1. How do submarine canyons affect sediment
