Document Summary
15 mark essay question one page length, use terminology, give solid examples. Where volcanoes form divergent, convergent, and hot spots. Associate with volcanoes with types of lavas. Sediment, 2 main types of sedimentary rock (clastic, non-clastic) What is a matrix (cement) and what is a clast? (grain) Methods of mass movement (suspended load, bedload) Channel morphology sinuosity (ratio of stream length to valley length) Highest erosion on cutbank deposition on point bar, erosion of cutbank. Meandering streams more likely to be found in areas of low slopes, braided in high slopes. Braided streams generally with coarse grained sediment. Urbanization effects on streams reduces water quality due to runoff (less seepage), erosion during floods. We must understand coasts, because most human population lives in coastal regions. What is wave base, how waves break into shore. Groynes, jetties, breakwater what they do to sediment. 3 main shoreline environments shoreface, beachface, dunes. Tide, flood tide, ebb tide, tidal range.
