1.   In the 1970’s, the Tellico Dam was being built on the Little Tennessee River.  This dam was intended to control flooding as well as generate hydroelectric power.  There was a heated dispute about the completion of the dam and the U.S. Supreme Court ruled that construction of the dam must be stopped due to the fact that an endangered species would be destroyed when the dam went into operation.  What was the species that would be threatened by the habitat destruction that this dam would cause?

A.       rainbow trout

B.       Johnny darter

C.       snail darter

D.       gila trout


2.  The construction of the Tellico Dam was indeed completed when the U.S. Congress granted certain exemptions to the Endangered Species Act.  One way a project like the Tellico Dam could be exempted is if an Endangered Species Review Committee decided that the economic benefits outweighed the potential harm to an endangered species.  What action was taken to provide benefit to the endangered species while at the same time allowing for the dam to go into operation?

A.        the endangered species was transplanted to nearby streams       and  allowed to thrive there

B.        the endangered species was cloned and its numbers in the population were thereby increased making it no longer an endangered species

C.        the endangered species was allowed to escape through the completed dam through sluice gates designed to allow the individuals to pass through unharmed

D.        the endangered species was eliminated and is now considered extinct so it is no longer a problem in that or any other ecosystem


3.  What is the advantage of building a dam on a river?

A.        provides escape for endangered species which are fleeing the fast-moving water of the river

B.        provides recreational activities and drinking water for people living in the community

C.        provides a clean and renewable source of electricity for people living in the area

D.        both choices B and C


4.  What is the disadvantage of building a dam on a river?

A.         the cost of building a dam is very high

B.         the reservoir created behind the dam can produce catastrophic floods

C.         the dam separates ecosystems both up stream and down stream

D.         the reservoir can become polluted by industrial runoff


 5.  What is the generation of energy via a turbine that is placed at the base of a dam parallel to the seashore that spins when the tides come in or out?

A.          OTEC

B.          tidal energy system

C.          hydroelectric energy

D.          Both B and C


6.  What is the generation of energy via a turbine and machinery that uses the difference between deep-ocean water and warm surface water to generate electricity?

A.          OTEC

B.          tidal energy system

C.          hydroelectric energy

D.          Both A and C


7.  What would be the best location for a tidal energy system?

A.          Bay of Florida

B.          Lake Superior

C.          Gulf of Mexico

D.          Bay of Fundy


8.  What would be the best location for OTEC?

A.          New York

B.          Hawaii

C.          Lake Erie

D.          The Great Salt Lake


9.  An old growth forest is considered to be

A.          a renewable resource

B.          a non renewable resource

C.          a microclimate

D.          poor in biodiversity


10.  Why are fossil fuels nonrenewable?

A.          They require hundreds of millions of years to form.

B.          Their ecosystems change forever when they are burned.

C.          They are converted to carbon dioxide when they are burned.

D.          They exist in a very small supply.


11.  Using renewable resources while ensuring that they are not depleted is a practice called

A.          sustainable development

B.          biological magnification
