Essay Questions
(DO IN BLUE BOOK)
Answer the following questions. Each answer is worth 15 points.
41. Describe the configuration of a beach and approaching waves to produce a longshore current.
What is the difference between longshore current and longshore drift and where exactly do these
processes occur?
