Test 1
1. Examples of non-sustainable human activities or behaviors include:
A) conservation practices.
B) using technology to improve car mileage.
C) recycling.
D) use of nonrenewable resources as if they were present in unlimited quantities.
E) attempts to limit human population growth.
2. What is the correct sequence of steps in the scientific method?
I. State the problem
II. Analyze and interpret the data
III. Develop a hypothesis
IV. Share the results with other scientists
V. Design and perform an experiment to test the hypothesis
A) I – III – V – II - IV
B) V – II – I – III - IV
C) III – I – V – II - IV
D) I- II – III – IV - V
E) V – IV- III – II - I
3. In addressing environmental problems, several stages can be followed. For example, when it was discovered that the rat population on the
island of Pumehana was out of control, scientists assessed the problem and formulated a model that suggested if a rat predator is introduced,
then the rat population will be significantly decreased.
The next step in addressing this environmental problem might be:
A) evaluation. After the release of the initial mongoose population, it is discovered that the mongoose is NOT a rat predator.
B) political action. A rat-infested island does not lure tourists so something MUST be done.
C) a risk analysis. If a mongoose is introduced to control the rat, what are the possible effects of this intervention?
,A) Divide number of people by resources needed and wastes produced
I=P÷T
B) multiply resource depletion times number of years divided by number of people
I=RxY÷P
C) multiply the number of people times affluence per person times resources needed and wastes produced
I=P x A x T
D) None of the above; the human impact cannot be measured
E) multiply birth rate times consumption patterns divided by available resources
I= B x C ÷ R
5. Which of the following stages comes LAST in addressing environmental problems?
A) scientific assessment
B) evaluation
C) public education and involvement
D) political action
E) risk analysis
6. The one central problem of environmental science that links all other problems together is that:
A) we are continually increasing the number of humans
B) we are polluting the environment.
C) we are using too much fresh water.
D) we are using up our supplies of fossil fuels.
E) we are depleting needed resources.
7. Poverty is associated with all of the following EXCEPT:
A) illiteracy
B) balanced nutrition
C) unsafe drinking water
D) low life expectancy
, B) deterioration of the atmosphere
C) pollution
D) increasing natural disasters
E) biodiversity decline
9. The interdisciplinary study of humanity's relationship with other organisms and the non-living physical environment is termed:
A) sociology.
B) ecology.
C) risk analysis.
D) environmental science.
E) political science.
10. The Ehrlich/Holdren model assesses human impact on the environment based on all of the following factors EXCEPT:
A) urbanization.
B) the number of people.
C) the environmental effects of the technologies used to obtain and consume the resources.
D) the amount of resources used per person.
E) the affluence per person.
11. In the scientific method, a hypothesis
A) all of the above
B) makes a prediction that can be tested
C) is a statement of fact
D) can only be tested once
E) is usually proven to be correct
