1. Physical and geological characteristics are used to classify the Earth's dynamic coastlines by their proximity to tectonic activity . We classify coastlines to help us better understand the process that shape them.
2. Shepard Coastal Classification
A. Primary, volcanic coast
B.
Primary, glacier
C.
Primary, glacial
erosion
D.
Secondary, coastal erosion
E.
Primary, barrial island
F.
Secondary, coastal plain
G.
Secondary, costal plain
H.
Primary, non-marine
I.
Secondary, mangrove coast
J.
Secondary, fault line coast
K.
Primary, decomposition
L.
Primary shore lines
M.
Primary coastal plain
N.
Primary, earthquakes
O.
Secondary, land erosion
P.
Secondary, wave cut beach
Q.
Secondary, land fall
R.
Primary, steep glaciers
Validation Statements for Classifications:
1. Arcadia National Park, Maine has glacial droughts
2. Cape Cod, Massachusetts has glacial droughts
3. Chesapeake Bay, Virginia has sedimentary extrusions
4. Atlantic City, New Jersey has beach over wash
5. Mississippi Delta, Mississippi has volcanic and glacial coasts
6. Kilauea Coast , Hawaii has volcanic coasts and volcanic explosion
7. San Francisco Bay, California has river deposition coasts
8. Indian River Lagoon, Florida has elevated wave-cut bench coasts
9. Cape Canaveral, Florida has barrier reefs
10. Florida Gulf Coast has wave deposition coasts
