Document Summary

Living with earth: an introduction to environmental geology (hudson) Chapter 9 changing coasts: wave refraction occurs around local extensions of the coast called, headlands, longshore currents, beach drift, surf zones, spilling breakers. Answer: a: rip currents can be dangerous even to strong swimmers. Answer: true: sea levels fluctuate between two high and two low tides each day. Answer: true: neap tides are those that occur when the tidal range is the greatest. Answer: c: what material is commonly found in most beaches, mud, pebbles, shell fragments, rocks, all of the above. 1: when the sediment debits exceed the credits in the sediment budget, neap tides happen, swells occur, erosion occurs, longshore drift occurs, all of the above. Answer: c: shoreline recession, beach retreat, and barrier migration are all terms to describe coastal erosion. Answer: true: coastal erosion is a costly natural hazard. Answer: true: most sea cliff erosion occurs during storms.
