Physical Geology-Fall 2013
A study of the earth's composition and forces which affect it; minerals, rocks, weathering, erosion, volcanism, structure, earthquakes and plate tectonics.
Physical Geology is an introductory course in geology. The course is a combination lecture-style class with a daily lab. Through the use of lectures, textbook, and lab exercises, students explore and study rocks, and the processes that form rocks and shape the Earth. The range of topics in this course covers everything from rock and mineral formation and identification, to plate tectonic, earthquakes, volcanoes, glaciers, deserts and remote sensing techniques.
The laboratory section of this course gives students a hands-on approach to learning about mineral and rock identification, topographic and geologic map reading, and geologic processes. Students will also participate in a variety of field trips which examine local geology.
If you are unable to go to on the field trip, you are required to write 2 short essays/discussions answering the two essay topics below. Let me be specific. EACH essay should be one page, 12 font, Times Roman Font, double spaced. DO NOT PLAGIARIZE.
Loggers want to clear cut all the trees on a steep mountain slope that rolls down to the town below. This is happening in northern Oregon and the rainy season is coming. The previous winter had extreme weather changes with many freeze-thaw cycles in rapid succession. Explain carefully why clear cutting all the trees would be a bad thing at this time and what may be at risk if the trees are all eliminated. List three types of preventative actions one could take to minimize these risks and explain why they are good preventative actions
Over the years, commercial fishermen have dredged the channels of the Mississippi River Delta so that their boats could get to the Gulf of Mexico to fish for shrimp easier. The dredging of the channels removed much sediment from the delta that acted as a barrier against floodwaters hitting the inhabited coast. When a hurricane came, the floodplain no longer contained enough sediment to act as a barrier that would dispense much of the hurricanes force before it hit inhabited land. Should the Mississippi Delta be allowed to resume it’s natural course of development and not be dredged or should the commercial fisherman have priority and the river channel be kept open for boats? What type of compromise could possibly be reached so that all parties needs are met? Explain your answer fully.
BOTH essays need to be e-mailed by Sunday, December 8th, and midnight.
