What is the difference between spring and neap tides?
Define wave height, wave length, wave period.
What is the difference between the two different types of
waves.
How is water and sediment transportation associated with
each of the following: wave refraction, beach drift, and longshore drift.
Know the different shoreline erosional landforms and
depositional landforms
What is the difference between a jetty, groin, breakwater,
and seawall? How does each alter/impact the beaches?
What are some hazards along shorelines?
What happens to the sand on the beach as a result of a
storm?
What are some examples of soft stabilization? What is the
purpose of beach nourishment? What are the pros and cons?
What are the differences between the Atlantic and Pacific
coasts?
How are emergent and submergent coasts formed? How does
changes in sea level influence a coastline?
Your Assignment:
Read
the Chapter: You are required to read this chapter in its entirety,
excluding pages 402-421. We will
just be covering the shoreline and sea level portions of this chapter, not
the glaciers.
Review
the powerpoints: Make sure to review the powerpoints for this chapter as
well. The slides represent the most important concepts of the chapter and
the ones that I will focus on for the test.
Watch
the animations and âBeaches are Movingâ video.
