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)

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.
