What is the relationship between particle size and slope of
the beach? - Answer-finer particle size=flatter beaches,
particle size depends on wave energy
Describe the seasonal changes in the profile of a beach -
Answer-winter: more intense storms=steeper, flatter berm
summer: dunes recover, berm returns
What causes the long shore current? - Answer-waves
approaching the shore at an angle
Are beaches affected by erosion, deposition or both? -
Answer-both erosion and deposition
Examples of coastal depositional land forms are: -
Answer-spits, bay mouth bars, barrier islands, lagoon,
tombolo, deltas
,2|Page
Coral reefs can affect coastal areas. In what type of
climate are coral reefs found? - Answer-clear, tropical
water, require sunlight, grow toward surface
Describe the characteristics of the Pacific, Atlantic, and
Gulf coast of the U.S. - Answer-A. The Pacific Coast
1. Active continental margin
2. Emergent
3. Mostly erosional features
4. High elevation on land
5. Water quickly becomes deep offshore
6. Sediment - mostly lithogenic from erosion of headlands
and nearby mountains
transported to ocean by streams
B. The Atlantic Coast
1. Passive continental margin
2. Submergent
3. Mostly depositional features
4. Low elevation on land
5. Drowned river valleys common
6. Water remains shallow for a long distance offshore
,3|Page
Sediment - more lithogenic if near larger streams,
biogenic, glacial sediment (in northeast)
C. The Gulf Coast
1. Passive continental margin
2. Submergent
3. Mostly depositional features
4. Low elevation on land
5. Drowned river valleys common
6. Delta's common
7. Water remains shallow for a long distance offshore
Sediment - large amounts from Mississippi and other large
streams, some biogenic
What processes can cause global or local changes in sea
level? - Answer-global (eustatic): occurs everywhere,
water added/removed from oceans change in volume of
ocean basins, expansion or contraction of water due to
temperature change
local: emergence (sea level decreases) or subsidence
(sea level increases) of coasts in locations b/c of plate
tectonics
, 4|Page
How has sea level changed in the Earth's geologically
recent past (last 18,000 years)? What is the primary cause
of this change? - Answer-eustatic change- at glacial
maximum up to 400 ft lower, many coasts flooded due to
sea level rise, glacial and stream sediment deposited on
locations exposed in the past, now continental shelf
Examples of coastal landforms caused by wave erosion
are: - Answer-headland, wave-cut cliffs, sea
caves/arches/stacks, wave-cut bench, marine terrace
Examples of coastal landforms caused by stream or
glacial erosion are: - Answer-drowned river valleys, fjords,
volcanic coasts
Beach sediment made of rocky material is
_________________ while sediment made of shells and
other skeletal material is _____________ - Answer-
lithogenic, biogenic
What is the relationship between wave energy and particle
size? - Answer-particle size depends on wave energy, high
energy=large particle size
