Question 4Sandbars have a distinct sediment profile.  What can be said in terms of the sediment on the seaward side of the bar crest?

 

coarse sediments, poorly sorted

 

coarse sediments, well sorted

 

fine grained sediments, poorly sorted

 

fine grained sediments, well sorted

Question 8Along a coastline that experiences high wave energy and is located in the higher latitudes, which type of beach sediment would be most likely?

 

 

 

sand

 

gravel

 

volcanic glass

 

mud

 

Question 9The presence of heavy mineral lag deposits on a beach indicates:

 

an accretionary beach cycle

 

an erosive (storm) beach cycle

 

a dissipative beach

 

Question 10Why are 60-80% of beaches presently experiencing high rates of erosion?
