BACK TO GAME The diagram shows a shoreline where approaching waves are refracted, or bent, until they approach the shore more head-on. Shade the area where erosion is likely to be occurring fastest. Circle the area where sand is most likely to be deposited to form a beach. Draw an arrow showing the direction of the longshore current between points A and B. (4 points) Shade the area where erosion is likely to be occurring fastest. Circle the area where sand is most likely to be deposited to form a beach. Draw an arrow showing the direction of the longshore current between points A and B. (4 points) Essay #1 Describe how individual sand particles move as an entire sand dune migrates. What can prevent a dune from migrating? As wind blows against the windward side of a migrating sand dune, individual sand particles are carried over the top. Over time this allows the particles to fall onto the leeward side moving the entire dune leeward. A dune may not migrate if the wind does not blow consistently in a particular direction. Vegetation can also hold a dune in place. Essay #2 Compare a beach made of sand with one made of pebbles. What factors may account for the difference in the makeup of the beaches? Over time, sand and clay on a beach are washed away by ocean waves. A sandy beach generally occurs where the sea floor has a gentle slope, and a constant supply of sand is delivered by rivers. A pebble beach generally occurs where the sea floor is steeper, and both sand and clay are washed away. Topic 5: $100 Answer Question: a. Choice 1 b. Choice 2 c. Choice 3 (correct answer) d.
