sand.
B.
Pumping sand onto the beach from some other area, temporarily
replenishing the sediment supply.

The distance from one wave crest to the next.
D.
The amount of time it takes for two wave crests to pass the
same point.
E.
A deposit of sediment resulting from a flood current passing
through an inlet.
F.
The sawing and grinding action of water armed with rock
fragments.
G.
Like the Atlantic coast of the United States, an area of sea level
rise relative to the land.
H.

the name of the shoreline feature shown there.
A.
B.
C.
D.
a.
Sea stack
b.
Tombolo
c.
Spit
d.
Baymouth bar
Question 8
The best place to look for crabs is between the high tide and
low tide zones (the tidal flat). Knowing this, would you expect
to find more crabs during a full moon/new moon or during a
quarter moon stage? Explain why.
Question 9
Discuss two reasons why summer temperatures in coastal
locations in Southern California are cooler than coastal
locations at the same latitude in Georgia.

5. Question 10
Examine the chart below. At what latitudes do we find the
maximum salinity? Briefly explain what contributes to high
salinities here versus polar and equatorial regions.
Question 11
A variety of techniques and efforts are used to stabilize
shorelines throughout the world. Discuss these techniques. Are
they temporary or permanent? Also, discuss at least two ways in
which the development/urbanization of coastal areas contributes
to shoreline erosion? (Hint: think about rivers and what they
contribute to our beaches. Also, what increases with the
creation of roads and rooftops?)
Your response should be at least 200 words in length.
Question 12
After the Deepwater Horizon oil spill in the Gulf of Mexico in
2010, the US put in place a temporary moratorium on new off-
shore oil developments. Now Congress has voted to renew off-
shore drilling with passage of the Restarting American Offshore
Leasing Now Act (H.R. 1230). What do you think about the
importance and safety of off-shore oil drilling? Should we
continue? Did we learn anything from Deepwater Horizon that
could make future off-shore oil developments safer (please be
specific)?
