Name: ________________________ Study Sheet - Exam 2 - Geography 1 – Chapters 9 & 11 The deepest single group of features on the ocean floor is (296F) Which of the following represents a second order of relief? (295) Terranes refer to (298+) Hawaiian volcanoes are (321) Mount Saint Helens is a type of composite volcano associated with an offshore subducted oceanic plate. (327) An instrument used to record vibrations in the crust is the (313) According to the text, the major impact of an earthquake prediction on a region would be (318) The ocean floor still remains a complete mystery to modern science. (292) The Hawaiian Islands mark one end of a hot-spot track that stretches to Alaska and Siberia. (292) Plains are identified as surfaces with local relief that does not exceed 100 m (325 ft). (295) Continental crust contains higher amounts of silica and aluminum compared with magma directly from the asthenosphere (uppermost mantle). (298) Folding is principally associated with earthquake activity. (301+) The Sierra Nevada and Grand Tetons are examples of tilted fault-block landscapes. (309) The Appalachian Mountain region is an example of a folded landscape. (301) A continental–continental collision produced over 1000 km (600 miles) of crustal shortening where India and the Asian landmass collided. (309) Earthquake damage may occur at distance from the epicenter, as was the case in the Mexico earthquake in 1985 and the Loma Prieta quake in 1989. (314) Watersheds (drainage basins) are defined by (364) Which of the following is incorrectly matched concerning drainage basins & divides? (364+) The area depicted in Figure 11.8 (see text), near the junction of the West Virginia, Ohio, and Kentucky borders is characterized by which drainage pattern? (367) The Amazon River has (383/363T) The suspended load of a stream consists of particles that (370+) The downstream portion of a river (371F) Relative to a meandering stream, (372) Niagara Falls is an example of a nickpoint related to differing resistances of bedrock strata. (374+) Excess sediment in a stream will produce a maze of interconnected channels causing the stream to be braided. (371) Relative to stream gradient, it is not possible to have both ungraded and graded portions on the same stream. (372+) The area of maximum velocity in a stream is usually on the inside of a bend near the point bar. (373F) 2 An oxbow lake is a form of braided stream. (371+) The Nile River, which flows into the Mediterranean Sea, is an example of an arcuate delta. (379) Streamflows are measured with a staff gauge and stilling well, among other devices and techniques. (386) Urbanization both delays and lessens peak flow as plotted on a hydrograph. (390+) The Mississippi-Missouri-Ohio river system is a single, major drainage basin system rather than many smaller drainage basins considered separately. (365) During the past 5000 years, the Mississippi River delta has assumed __________ (number of) deltaic forms. (379/382F) The present bird-foot delta has been building for the past __________ years at least. (379) Other Considerations: What is the difference in energy released between adjacent numbers on the Richter Scale of Magnitude (313) Know the folds: anticlines/synclines and their relation to compression/tension/shear (301) The San Andreas Fault is what kind of fault and/or plate boundary (305) What type of faulting, forces and features occur in the Basin and Range Province of western United States [Nevada and parts of California as well as other states] (305/308F) What is the dominate feature of delta formation and how do deltas form (377/379) What is the difference between the focus and epicenter of and earthquake (314) What are the differences between lavas and pyroclastics (319) Drainage patterns and types of surfaces they form on (368) The Mississippi, Columbia and Yukon River flow into which oceans, respectively (365F & 379)
