1. Silicate minerals are: subdivided into light colored, low-density felsic minerals and dark colored, high-density mafic minerals. the main ingredients in igneous rocks. examples of primary minerals. all of the above. 2. Compared to rhyolite, basalt: is lighter colored. has a lower density. results in less explosive volcanic eruptions. is an intrusive igneous rock while rhyolite is an extrusive igneous rock. 3. A comparison of oceanic crust and continental crust reveals that oceanic crust is: less dense than continental crust. thicker than continental crust. composed primarily of mafic minerals while continental crust is primarily felsic. older than continental crust. 4. If you wanted to know where the boundaries to the earth's lithospheric plates are located, which of the following would be most helpful? A map showing the geographic distribution of earthquakes. A map showing the geographic distribution of volcanic activity. A map showing the geographic distribution of mid-oceanic ridges. A map showing the the geographic distribution of deep ocean trenches. 5. Which type of plate boundary is characterized by the creation of new lithosphere, basaltic volcanism, and shallow focus earthquakes? Divergent boundaries (rift zones). Transform boundaries Convergent boundaries classified as subduction zones Convergent boundaries classified as continental collisions 6. Plate motion along divergent boundaries may result in: reverse faults and the formation of faulted mountains. the formation anticlines and folded mountains. normal faults and the formation of faulted valleys. the formation of synclines and folded valleys. 7. The Hawaiian Islands are an example of: composite volcanoes that form a volcanic island-arc. volcanic islands that have formed along an oceanic rift zone. shield volcanoes associated with an oceanic hotspot. strato volcanoes associated with a subduction zone. 8. A drainage basin: is a low spot in the landscape where water accumulates. is land, such as the UWSP campus, that contributes water to nearby streams. contains streams and rivers that are not connected together. is a high spot of land, such as a ridge top, that divides the flow of water in two different directions. 9. The sediment load of rivers: may be transported as dissolved, suspended, or bed load. may come from the stream channel or from the land area surrounding the channel. is affected by water depth and flow velocity. all of the above. 10. Point bar deposits: are located on the outside of meander bends. may contain a series of bars and swales that indicate the former location of the river channel. result from vertical deposition (aggradation). form on the opposite side of the channel from riffles. 11. Which of the following floodplain landforms in the diagram below is correctly identified? B is a meander scar. C is an incipient oxbow lake. E is a yazoo stream. F is a natural levee. 12. Glaciers may be classified as: advancing (growing) if their net mass balance is negative. ice sheets if their flow is restricted by valley walls. stationary (staying the same size) if their net mass balance is zero. all of the above. 13. Which of the glacial landforms shown in the diagram below is correctly identified? A is pointing to lateral moraines. B is pointing to horns. C is pointing to aretes. G is pointing to hanging valleys. 14. During the last ice age: the carbon dioxide content of the atmosphere was higher during interglacials than during glacials. temperatures were uniformly cold. temperatures increased during glacials and decreased during interglacials. the continents were located at colder latitudes than they are today. 15. According to the astronomical theory, glacials are more likely to occur when: the earth's orbit is more circular than when it is more elliptical. the tilt of the earth's axis of rotation is greater than when the tilt is less. the northern hemisphere winter occurs when the earth is farthest from the sun. both (b) and (c).
