Which of the following identifies and describes the equipment needed to determine best how much water infiltrated the soil?

A ruler should be used to measure the level of water above the pavers in both pallets immediately after pouring the water over the pavers and immediately after the one-hour wait time.

Which of the following is an unintended environmental consequence of aquaculture?

Contamination of local surrounding water by organic waste

A farmer grows several crops on a farm that has mostly shallow, sandy soil. Which of the following irrigation methods would be the best suited for this farm?

Drip irrigation

Farmers use various methods of irrigation on crops. Which of the following statements correctly pairs an irrigation method with an advantage or disadvantage?

Flood irragation is often used in agricultural fields

Which of the following irrigation methods is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight?

Furrow irrigation

Which of the following statements is best supported by the data shown in the table?

Green roofs reduced ammounts of ammonium because the vegetation absorbed the pollutant

Which of the following describes an aspect of urbanization that would most increase

Increased amounts of waste per unit area in urban areas that leads to higher rates of decay and decomposition

Which of the following describes an aspect of urbanization that would most increase the amount of carbon dioxide released into the atmosphere compared to rural and suburban areas?

Increased waste per unit

Assume that the rainwater from one of the green roofs ran off directly into a nearby lake. Water quality results from which of the following parameters show that the green roof would likely improve water quality in the lake?

Nitrate

Which of the following is likely to minimize soil erosion?

No-till agriculture

The major cause for the decline in the worldwide catch of fish since 1990 is

Overfishing

Which of the following is the dependent variable in the study?

The infiltration rate of the water

Which of the following best describes acid mine drainage?

The leakage of water containing toxic materials from coal and metal mines

Which of the following statements best identifies the author's perspective in terms of utilizing science technology for future agricultural advances?

The only way to meet the global demand for more food is to fully utilize new science technologies to advance agriculture.

Which of the following is the independent variable in the study?

The type of pavers used in the pallets

One example of the tragedy of the commons occurs when trees are harvested from tropical rain forests without any regulations. Which of the following best describes why this is an example of the tragedy of the commons?

Timber producers remove as much timber as possible as cheaply as possible

Sustainable use of forests in the United States would likely be encouraged by

cutting small groups of medium- and large-sized trees in uneven-aged forests

Many communities experience the tragedy of the commons. One way a local community might regulate a shared and limited resource and reduce the tragedy of the commons is to

divide the resources into parcels and assign them to individuals

One way that consumers can help prevent a decrease in the number of fish species that are experiencing population declines is to

eat fish that are caught using sustainable harvesting methods, therefore ensuring fish populations remain stable and reducing the amount by-catch harvested

Industrial logging threatens many forested ecosystems. Which of the following environmental consequences will most likely result from clear-cutting deciduous forests for logging?

more carbon dioxide into the atmosphere and increase in athropgenic climate change will result from clear cutting forests for logging

help decrease flood frequencies and flood sizes that are caused by urbanization?

new permeable materials for roads and sidewalks

Overuse of groundwater in coastal areas could result in?

saltwater intrusion

Farmers need to make many decisions about how they grow their crops. One of these decisions is whether to use synthetic fertilizer or organic fertilizer, such as manure.An advantage of using synthetic fertilizer instead of organic fertilizer is that

synthetic fertilizer provides more macronutrients to the crops

The farming of fish such as salmon at aquaculture facilities poses a threat to marine ecosystems because

the farmed fish can escape and out-compete wild fish for food and territory

which of the following is the best example,of an economic approach to reduce overfishing for a fish species with a declining population?

the federal government sets a catch limit (per person or per boat) for the species and imposes a tax on any extra fish that are caught.

Which of the following is the most likely result from clearing mature, forested land and converting it into agricultural land that would be used for cattle grazing?

there will be a reduction in the uptake of atmospheric carbon dioxide

The data in the table show mean concentrations (mg/L)(mg/L) of pollutants in rainwater leaving either green or conventional roofs. Which of the following data would be needed to calculate the total amount of a pollutant leaving the roof during and following a rainstorm?

total volume of rainfall
