Term
Define: Science
Definition
The systematic gathering of knowledge
about the world and organizing and condensing that knowledge into testable laws and theories.
Term
Define: Policy
Definition
A plan or statement of intentions about a course action or inaction intended to accomplish some end.
Term
Define: Politics
Definition
A struggle among competing interest
groups as they strive to shape public policy to suit their own agendas.

To the policy with the greatest cumulative welfare and least negative impacts. i.e. Rational choice
Term
Why is rational choice typically not employed in policy making?
Definition
1.Conflicting views are not comparable 2.Policy makers not motivated by societal goals.
3. Lg. investments create path dependence.
4. Segmented nature of large bureaucracies makes it difficult to coordinate decision making.

Term
Define: Environmental Law
Definition
Body of rules, decisions, and actions concerning environmental quality, natural resources, and ecological sustainability.
Term
Define: Statue Law
Definition
Formal documents enacted by legislative branch declaring, commanding, or prohibiting something.
Term
Define: Case Law
Definition
Derived from court decisions in both civil and criminal cases.
Term
Define: Administrative Law
Definition

There were none.
Term
Who enacts state or federal laws?
Definition
Executive Branch (Governor or President}
Term
What is the purpose of the judicial branch and how is it related to case laws?
Definition
The judicial branch interprets the meaning and constitutionality of statutes. The first judge to make a ruling on a certain statute sets precedent to be used as an example in subsequent trails.
Term
What are the major problems with international treaties and conventions on environmental policy?
Definition
1.Most are vague
2.Most nations are unwilling to give up sovereignty
3.International court has no enforcement powers
Term
What is the MOST important characteristic of natural systems?
Definition
Their resilience; flexibility is more important than strength.
Term
Define: Coast
Definition
Where land and water meet.
Term
Define: Coastal Zone
Definition
Includes the coastal ocean (or Great Lake) as well as the portion of land adjacent to the coast that influences coastal waters.
Term
Why is the coastal zone important?
Definition
1. Highly productive biological communities 2. Human Use (i.e. oysters, etc.)

Term
What are the characteristics of the U.S. Gulf and East Coasts?
Definition
wide
continental shelf; broad, flat coastal plain, high sediment flow from rivers
Term
Define: Coastal Uplands
Definition
Includes all land that yield substantial storm-water runoff directly to coastal waters via streams, storm drains, or overland flow.
Term
Where and what is the 100 year flood level?
Definition
Lower boundary of the coastal uplands that has a 1% chance of flooding in the current year if it flooded in the previous year.
Term
What problems occur when coastal uplands are developed?
Definition
Storm-water is unable to be distributed properly and floods the developed area. Heavy metals, excess nutrients, etc being to build up in the ground water.
Term
Define: Coastal Floodlands
Definition
Portion of the coastal floodplain that lies above the yearly reach of tides and is sporadically struck by storm waves and flooded by storm tides.
Term
What coastal region is most attractive for development and why?
Definition
Coastal floodlands, b/c it is flat and accessible.
Term
Define: Saltwater Marsh
Definition
Areas along the shore where vegetation grows that can tolerate saturated salty soil and remove silt, toxic chemicals, and excess nutrients from the water.
Term
Define: Bluffs
Definition
The seaward edges of marine terraces, shaped by waves and currents, and uplifted from the ocean floor.
Term
Define: Rocky Shores
Definition
Form on high-energy coasts where mountains meet the ocean or glaciers have removed fine-grained sediment.
Term
Define: Dunelands
Definition
Area of dunes, sand ridges, and flats b/t the upper line of the beach and higher ground. Extend landward as far as the land is subject to active gain or loss of sand.
Term
What is the important of salt marshes?
Definition
Act as a natural water filter by removing toxins, excess nutrients, etc. from the water.
Term
What is the importance of coastal uplands?
Definition
Channel flood waters.
Term
What is the importance of dunelands?
Definition
Serve as a storm surge buffer and are a source of sand for the beach.
Term
Define: Beaches
Definition
Unvegetated face of the shoreline that extends from the annual highest tide mark to the annual lowest tide mark.
Term
What are the typical zones of a barrier island?
Definition
Sandy beach, frontal & secondary dunes, interior wetlands & maritime forest, a backshore zone, and a lagoon or sound that separates the island from the mainland.
Term
Define: Estuary
Definition
Highly productive ecosystems with a highly variant salinity gradient located where a river meets the ocean.
Term
What types of habitats are found in coastal waters?
Definition
Seagrass beds, Coral reefs, kelp forests, etc.
Term
What are the major forces that shape the coastal zone?
Definition
Wind, waves, currents, tides, hurricanes, tropical storms, sea level rise,
Term
How does wind shape the coastal zone?
Definition
1. Moves sediment
2. Generates waves & currents
3. Storm winds uproot vegetation and damage the existing environment.
Term
What causes waves?
Definition
Waves are generated when the surface of the ocean is disturbed by wind, tides, and/or seismic activity.
Term
How do waves shape the coastal zone?
Definition
Have a large impact on sediment transfer.
Term
What factors determine wave height?
Definition
Wind velocity, duration, & fetch.
Term
What causes current?
Definition
Can be caused by breaking waves, wind, rotation of the Earth, temp, salinity, and/or tides.
Term
Define: Tides
Definition
Rise and fall of the ocean caused by the gravitational forces exerted by the Moon and the Sun.
Term
How do tides effect the coastal zone?
Definition
Move sediment and influence the zonation of coastal organisms and landforms.
Term
How do hurricanes and tropical storms shape the coastal zone?
Definition
High winds and storm surge. (~8.5/year)
Term
