and list the major types of life that dominated the Precambrian, Paleozoic, Mesozoic, and Cenozoic eras. 9. Discuss the various types of mass wasting in terms of controlling factors/causes and causative processes. 10. Describe stream action and associated landscape development, including how sediment is transported as bed load, suspended load, and dissolved load. 11. Explain why groundwater is a critical natural resource, and distinguish between porosity and permeability, indicating how these factors influence groundwater movement, groundwater pollution, and groundwater erosion (i.e., karst topography). 12. Define the term glacier, differentiate between alpine glaciation and continental glaciation; contrast the erosional and depositional features of both continental and alpine glaciers. 13. Describe common desert and coastal landforms and the underlying processes responsible for their development. 14. Explain the origin of various geologic structures, including folds, faults, joints, and unconformities, and how each type is classified. 15. Discuss the relationship between faults and earthquakes; describe the characteristics of various seismic waves, explain how seismic wave analysis contributes to our knowledge of Earth's interior; relate the concept of plate tectonics to earthquake distribution. 16. Describe the general topography and principal landforms observed on the ocean floor, and describe the geologic nature and significance of mid-oceanic ridges. 17. Outline the theory of plate tectonics, including supporting lines of evidence, and discuss the principal types of plate boundaries and their characteristic geologic features. 18. Discuss the characteristics of Earth's major mountain belts, and explain the concept of orogeny as it applies to plate tectonic theory. SECTION II 1. COURSE OUTLINE AND SCOPE: A.
