Your answer is correct. The Conservation Reserve Program (CRP) is a voluntary subsidy program that pays farmers to stop producing crops on highly erodible farmland. Instead farmers are required to:
Entry field with correct answer strip crop native plants with grain crops on the erodible land plant native grasses or trees on the highly erodible land and then ―retire‖ it from further use for 10 to 15 years develop and adopt a 5-year conservation plan for their farms that includes erosion-control measures, and if they do not comply, they lose federal agricultural subsidies such as price supports plant shelterbelts to reduce the impact of wind erosion Question 10 Correct answer. Your answer is correct. In one tree harvesting model called ___, in the first year of harvest, undesirable tree species and dead or diseased trees are removed and then subsequent harvests occur at intervals of several years, allowing time for remaining trees to grow. Entry field with correct answer clear-cutting
even-age harvesting selective cutting shelterwood cutting Question 11 Correct answer. Your answer is correct. Which of the following can be found in U.S. National Parks? Entry field with correct answer Significant modern architecture. Economically significant areas or buildings. Historic battlefields. Farm land. Question 12
Correct answer. Your answer is correct. Which of the following statements regarding rangelands in the United States is TRUE? Entry field with correct answer Approximately 50% of the total land area in the United States is rangeland, and most of it is located east of the Mississippi. The condition of U.S. rangelands which declined starting in the 1930s, at the time of the Dust Bowl, have continued to be on the decline largely due to the lack of federal legislation. Public rangelands in the U.S. are managed by the National Park Service with a preservation mandate and thus cannot be used for grazing private livestock. Restoration of degraded rangeland in the U.S. is a slow and costly process but effective as a result of techniques that include seeding in places where plant cover is sparse or absent, conducting controlled burns to suppress shrubby plants, constructing fences to allow rotational grazing, and controlling invasive weeds. Question 13
Correct answer. Your answer is correct. What is the relationship of overgrazing to desertification? Entry field with correct answer Overgrazing is the destruction of a grassland ecosystem; desertification is the destruction of a desert ecosystem. Overgrazing results in barren exposed soil; if erosion continues, it contributes to desertification. Overgrazing is brought about by livestock operations; desertification is brought about by crop cultivation. Overgrazing and desertification are both a result of the introduction of non-native species coupled with extended droughts. Question 14 Correct answer. Your answer is correct.
Which of the following statements about the Forest Stewardship Council is TRUE? Entry field with correct answer The FSC is a German organization that acts as a legitimate third party in certifying wood that is harvested using environmentally sound and socially responsible practices. FSC certification is based on the sustainability of the timber resource, socioeconomic benefits provided to local people, and maintenance of forest ecosystem health. FSC is criticized by some who are skeptical about the reliability of FSC investigations and the economic viability of this type of forestry. All of the statements are true. Question 15 Correct answer. Your answer is correct. What is an important ecosystem service provided by forests? Entry field with correct answer
They fix large amounts of oxygen, removing it from the atmosphere They promote soil erosion They maintain watersheds They provide habitat for a few animal species Question 16 Your answer is correct. The photo below BEST illustrates: a wildlife corridor a clear-cut
rangeland tundra Question 17 Correct answer. Your answer is correct. A legal agreement that protects privately owned rangelands, forests or other property from development for a specified number of years is termed: Entry field with correct answer a public rangeland. a national park.

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
Examples of non-sustainable human activities or behaviors include: recycling attempts to limit human population growth using technology to improve car mileage use of non-renewable fossil fuels Question 5 In the scientific method, a hypothesis
