ESCI 1101: Earth Sciences – Geography –atmosphere, energy balance, climate, weather, water resources, coasts, soils, ecosystems –One of ~5 sections, mine not linked to a lab, all non-majors, 40 students –Text: Christopherson’s Geosystems UNCC: 22,000 students, suburban campus, mostly regional and in-state Context
3
–Coastal processes, incl. longshore drift –Coastal landforms –Barrier Islands: location, structure, movement, hazards Ex. Cape Hatteras lighthouse relocation Ex. Effects of Katrina on Barrier Islands –Coastal structures: groins, jetties, breakwaters Preceding Content
4
–Get students talking to each other –Have students evaluate competing scientific claims in the news media –Have students experience the complex factors involved in environmental policy-making Goals of the activity
5
Form where: –Low tidal range –Sediment from coastal plain rivers –Shallow continental shelf Characteristic structure (above) Unstable and mobile –May migrate landward –Ex. Relocation of Cape Hatteras lighthouse Barrier islands
