Question 1

 

What is the environmental significance of the process of “consumption”?

 

Consumption can outstrip the natural resources available and lead to overexploitation of the environment.

Extravagant consumption can create an environment of raising one’s status among peers.

 

The process of consumption is an economic act, providing the “demand” necessary for the “supply” of the environment.

 

Consumption can generate economic growth that relies significantly on the importation of natural resources, which benefits the environments of less-developed countries.

 

Question 2

 

Which of the following describes the relationship among population growth, consumption of natural resources, and environmental degradation?

 

When individual demands on natural resources are far greater than the requirements for survival, people in affluent nations deplete resources and degrade the global environment through increased consumption of nonessential items to satisfy their desires.

 

Rapid population growth does not overwhelm and deplete a country’s soils, forests, and other natural resources when the amount of resources essential to an individual’s survival is small.

 

Rate of resource consumption affects the environment far less that the explosion in population.

 

There is no relationship between population growth, consumption of natural resources, and environmental degradation.

 

Question 3

 

Non-renewable resource is to renewable resource as

living is to non-living.

limited supply is to sustainable supply.

 

tree is to coal.

 

wind energy is to fossil fuel energy.

 

Question 4

Question 5

 

In the scientific method, a hypothesis

 

is a statement of fact

 

makes a prediction that can be tested

 

is usually proven to be correct

 

can only be tested once

 

Question 6

 

A state agency has contacted you to do a scientific assessment of kudzu in a nature preserve in southern Georgia. They are concerned about the effects of the non-native invasive vine on a small rare plant that grows on the forest floor in the preserve, but which is found nowhere else in the state. Kudzu is only growing in the east side of the preserve because it hasn’t yet had time to invade further. In order to assess the effects of kudzu on the rare plant, you set up the following experiment:

 

Site 1. On the east side of the park with the kudzu, you set up ten 1m × 1m plots on the forest floor. In each plot you count the number of individuals of the rare plant.

 

Site 2. On the west side of the park without the kudzu, you set up ten 1m × 1m plots of the forest floor. In each plot you count the number of individuals of the rare plant.

 

Which of the following represents the hypothesis that you are testing with this experiment?

 

Kudzu will eventually grow on the west side of the park.

 

Kudzu will kill off the trees in the preserve by strangling them.

 

Kudzu should be removed from the preserve because it is killing the rare plant.

 

Kudzu is negatively affecting populations of the rare plant in the preserve.

 

Question 7

 

All of the following statements describe environmental science EXCEPT:

 

The goal of environmental science is to try to establish general principles about how the natural world functions.

 

Environmental scientists seek to develop viable solutions to environmental problems that are based as much as possible on scientific knowledge.

 

Since environmental problems are generally complex and scientific understanding of them is often less complete, environmental scientists are often called on to reach scientific consensus before the data are complete.

 

No exceptions, all of the above statements describe environmental science.

Question 14

 

What does the image below represent and how does it relate to designing sustainable cities?

 

Residents of squatter community, like this one, must be evicted in order to achieve the goal of making cities more sustainable.

 

Comparing the squatter community in the foreground to the skyscrapers in the back shows how a city can be transformed when sustainable city design is embraced as a goal for re-development.

 

Squatter communities, due to their lower resource consumption, should be left unchanged as living in such conditions is compatible with the goals of sustainable living.

 

Squatter settlements should be improved to provide basic service such as clean water to drink, sewage treatment, and garbage pickup so as to provide a better quality of life for the poorest of the poor.

 

Question 15

 

Environmental sustainability implies:

 

the actions of humans directly impact the wellbeing of the natural environment

 

future generations will have the resources necessary for quality of life

 

the environment can function indefinitely without going into a decline from the stresses imposed by human society on natural systems

 

all of these choices

 

Question 16

 

A deep ecology worldview would support all of the following EXCEPT:

 

Nonhuman life forms have value that is independent of the usefulness they may have for narrow human purposes.

 

The richness and diversity of life contribute to the flourishing of life on Earth and humans have no right to reduce this richness and diversity except to satisfy vital needs.

 

The inherent responsibility of individuals to implement changes in society so that humans can flourish.

 

A spiritual respect for life reflected in appreciating quality of life rather than adhering to a high standard of living.

 

Question 17

 

What does the diagram below illustrate?

Question 1

 

Which of the following statements about nutrient cycling is TRUE?

 

Bacteria and fungi are involved in nutrient cycling as they decompose detritus transforming large organic molecules into small inorganic molecules, including carbon dioxide, water, and nutrient minerals like nitrates.

 

Nutrient cycling is the pathway of various nutrient minerals or elements from the environment through organisms and back to the environment.

 

Nonliving processes are also involved in nutrient cycling, such as the weathering of the parent material replaces some nutrient minerals lost through erosion.

A = zinc; B = gypsum

 

A = molybdenum; B = sulfur

 

A = mercury; B = potassium

 

A = nickel; B = magnesium

 

Question 4

 

Subduction occurs:

 

when one tectonic plate slides underneath another.

 

due to mining activities.

 

because of the Coriolis effect.

 

on the leeward side of a mountain.

 

Question 5

 

Planting the same crop year after year:

Which of the following statements about soil is NOT TRUE?

 

Soil consists of mineral and organic matter modified by the natural actions of agents such as weather, wind, water, and organisms.

 

Soil formation is a continuous process that takes a long time, sometimes thousands of years, both because the process of rock disintegrating into fine mineral particles is slow, and time is also required for organic material to accumulate in the soil.

 

An area’s terrain influences soil formation — steep slopes encourage soil formation and accumulation while valleys discourage the formation of deep soils.

 

Minerals, the main component of soil, provide anchorage and essential nutrient minerals for plants, as well as pore space for water and air.

Increased soil erosion may be caused by all of the following EXCEPT:

 

construction of buildings.

 

construction of roads.

 

construction of shelterbelts.

 

clearcutting large forested areas.

due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments.

 

approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions.
