Lab 9: Oceans & Coastal Systems
GEOG 1113L – Introduction to Landforms Lab
Name: _____________
I. How the Coast Works
1. What area is considered the shore? (2 points)
The shore is the area between high and low tide.
2. Describe the type of area that is required for a beach to form. (4 points)
The type of area required for a beach to form is a sheltered environment, like a bay.
3. Beaches require constructive waves, which are defined as what? (2 points)
constructive waves are waves when the swash is stronger.
4. What is longshore drift? (3 points)
Longshore drift is the movement of sediment along the shore by waves. (swash)
5. What is the difference between attrition and abrasion? (3 points)
Attrition is when rocks strike each other. Abrasion is when rocks rub together .
6. What artificial barrier do humans use to protect the coast from high tide? (1 point)
The artificial barrier humans use is made of rocks, it's called riprap to protect the coast from
high tide.
7. What barrier is used to protect against longshore drift? (1 point)
to protect against longshore drift groynes are installed.

II. Coastal Systems
This activity can be completed with the use of the USGS website links provided. Respond to each
question in your own words.
Go to the link http://pubs.usgs.gov/circ/c1075/agencies.html and review the list of federal
organizations with regulatory or research responsibilities for our coasts to answer the following
questions. Provide both the agency’s acronym and entire name for full credit.
1. Which federal organization administers NFIP? (1 point)
the Federal Emergency Management Agency administers NFIP
2. NFIP is an acronym which stands for what? (1 point)
NFIP stands for National Flood Insurance Program
3. Which federal organization regulates the discharge of coastal pollutants and the disposal of
dredged sediments? (1 point)
the US Environmental Protection Agency regulates the discharge of coastal pollutants and the
disposal of dredged sediments
4. Which federal organization conducts applied research and development for design,
construction, operation, and maintenance activities related to harbors, navigational waterways,
and coastal protection? (1 point)
the US Army Corps of Engineers
5. Which federal organization manages extensive coastal lands as wildlife preserves; conducts
research on coastal wetlands, fish and wildlife populations, and changes in habitat? (1 point)
the US Fish and Wildlife services
6. Critical thinking: Which federal organization would be responsible for reviewing engineering
plans for a dam on a river? (1 point)
the US Army Corps of Engineers
Now go to the link http://pubs.usgs.gov/circ/c1075/types.html and review the four types of coasts
listed there. Answer the following questions.
7. Which type of coast listed in the link is the type of the Florida Keys? (1 point)
coral reefs
8. What importance do coastal wetlands hold? (3 points)
They are rich in wildlife resources and provide nesting grounds, meaning there’s a lot of
wildlife species living there.
9. Which type of coast protects coasts from waves and storms? (1 point)
coral reefs
10. The website describes the differences in geology between rocky and sandy coasts. According to
the information in this web link, which type of coast is dominated by depositional features?
Rocky or Sandy? (1 point)
sandy beaches are dominated by depositional features
