Which of the following is true regarding the driving force behind organic farming quizlet?
Which of the following is true regarding the driving force behind organic farming? The driving force behind organic farming is concern about human health impacts of chemical pesticides.
Which of the following is true regarding the path of energy and nutrients in an ecosystem?
Which of the following is true regarding the path of energy and nutrients in an ecosystem? Energy flows through ecosystems, while nutrients cycle in ecosystems.
How would the dead zone in the Gulf of Mexico be affected by record flooding in the Midwestern United States quizlet?
How would the dead zone in the Gulf of Mexico be affected by record flooding in the Midwestern United States? The size of the dead zone would increase. What is Hubbert’s Peak? Which two processes allow water to enter the atmosphere in a gaseous state?.
Which of the following is correct regarding soil quizlet?
Which of the following is correct regarding soil? Soil is an inorganic by-product of geological processes. Soil is composed of mineral matter only. Soil is a dynamic natural body composed of both minearl and organic matter.
Which of the following is true regarding peak oil production in the lower 48 states as compared to Alaska?
Which of the following is true regarding peak oil production in the lower 48 states as compared to Alaska? Oil production peaked in Alaska after it peaked in the rest of the United States.
Are fossil fuels organic or inorganic?
Inorganic deposits of carbon in the lithosphere include fossil fuels like coal, oil, and natural gas, oil shale, and carbonate based sedimentary deposits like limestone.
Which of the following is true of the relationship between energy use and quality of life quizlet?
Which of the following is true of the relationship between energy use and quality of life? Energy use has no relationship to overall quality of life. Generally, the quality of life is directly related to an area’s energy use per person. Increased energy use brings about a lower quality of life.
Which is true of human impacts on the global water cycle quizlet?
Which is true human impacts on the global water cycle? Withdrawals of surface water and groundwater for agriculture, industry, and domestic uses deplete rivers, lakes, and aquifers.
What is true about trophic levels?
The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain.
Which of the following appears to be the best way to reduce dead zone pollutants quizlet?
Which of the following appears to be the best way to reduce dead zone pollutants? Using bioreactors and phosphorus filters. Decreasing soil erosion would have which of the following effects? It would decrease the amount of phosphorus getting into waterways.
What are the two types of water pollution based on where pollution originates?
There are many causes for water pollution but two general categories exist: direct and indirect contaminant sources. Direct sources include effluent outfalls from factories, refineries, waste treatment plants etc.. that emit fluids of varying quality directly into urban water supplies.
Which of the following is true regarding the addition of organic matter and humus to soil quizlet?
Which of the following is true regarding the addition of organic matter and humus to soil? Adding organic matter and humus to soil increases nutrient-holding capacity and decreases infiltration. Adding organic matter and humus to soil decreases nutrient-holding capacity and increases infiltration.
Which of the following is correct regarding soil formation factors?
The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time. If a single parent material is exposed to different climates then a different soil individual will form.
Which of the following are soil forming factors quizlet?
The five principal soil-forming factors are geology, climate, topography, biology, and time.
Which of the following is correct regarding soil color quizlet?
Which of the following is CORRECT regarding soil color? Soil color is used solely to determine the moisture content of soil—darker soils have a higher moisture content, whereas lighter soils have less water content. Dark soils always indicate high organic content.
What is peak oil production?
Peak oil refers to the hypothetical point at which global crude oil production will hit its maximum rate, after which production will start to decline. In the traditional vision of peak oil, the production decline accelerates as the cost of extracting new reserves grows.
When did oil production peak?
According to the International Energy Agency, production of conventional crude oil (as then defined) peaked in 2006, with an all-time maximum of 70 million barrels per day.
For what peak year does the curve best match the actual trend in oil production?
On the basis of his theory, in a paper he presented to the American Petroleum Institute in 1956, Hubbert correctly predicted that production of oil from conventional sources would peak in the continental United States around 1965–1970.
What are fossil fuels chemistry?
Fossil fuels are compound mixtures made of fossilized plant and animal remnants from millions of years ago. The creation of fossil fuels—either oil, natural gas, or coal—from these fossils is determined by the type of fossil, the amount of heat, and the amount of pressure.
What are the 4 types of fossil fuels?
Petroleum, coal, natural gas and orimulsion are the four fossil fuel types. They have a variety of physical, chemical and other essential properties in general, but the most vital thing regarding fossil fuels, perhaps, is that they are not green. Fossil fuels are made from plants and animals that decompose.
What are the 3 main types of fossil fuels?
fossil fuel coal, oil, or natural gas. Fossil fuels formed from the remains of ancient plants and animals.
Which of the following is true concerning energy flow through an ecosystems food chain?
Which of the following is true concerning energy flow through an ecosystem’s food chain? Energy is lost at each successive energy level in the chain.
Which of the following best describes the relationship between economic growth energy use?
Which of the following best describes the relationship between economic growth and energy use? Increased energy use leads to increased economic growth.
How does the use of hydroelectric energy compare to the use of coal?
Hydroelectric energy uses the movement of water to spin a turbine and produce electricity. Coal is a fossil fuel that is burned as an energy source, which results in emissions such as carbon dioxide, nitrogen, and sulfur.
