100
This agriculture technique includes growing different crops during different times of the year and can used as a form of IPM.
What is crop rotation?
100
This commercial method of harvesting timber involves getting rid of all trees in an area.
What is clear-cutting?
100
This is described as expansion of urban cities into surrounding areas, with movement of people from high density areas to low density areas.
What is urban (suburban) sprawl?
100
This phenomenon is caused by sulfide minerals, left at old coal mines from tailings, reacting with water to contaminate waterways.
What is acid mine drainage?
100
This is used as a form of IPM when a natural predator is brought in to control the pest.
What is biocontrol?
200
This agricultural technique is most effective at limiting soil erosion by minimizing physical disruption to soil as much as possible.
What is no-till agriculture?
200
These are two environmental problems caused by free-range grazing.
What are desertification and overgrazing? Can also include soil erosion, loss of topsoil, soil nutrient depletion, etc.
200
This is a method for dividing land into different sections to allow for specific types of development (commercial, residential, municipal, etc.) in each section.
What is zoning?
200
This method of commercial fishing (not an aquaculture) destroys the ocean floor and most resembles clear-cutting.
What is bottom trawling?
200
This agricultural intercropping technique involves integrating planting trees with rows of crops.
What is agroforestry or alley cropping?
300
This adds targeted nutrients to soil and was used during the Green Revolution. However, excess amounts can lead to eutrophication in bodies of water.
What are synthetic fertilizers?
300
This type of agriculture involves intentionally burning vegetation to add nutrients to infertile soil in order to give the soil a temporary nutrient boost.
What is slash and burn agriculture?
300
These are strips of land that connect parks with neighborhoods to maintain greenery and vegetation in urban spaces.
What are greenbelts or greenways?
300
This a solid material (that can be mined) from which economically valuable minerals can be extracted from.
What is an ore?
300
This is the most efficient irrigation method that minimizes the loss of water to evaporation and runoff.
What is drip irrigation?
400
This agricultural technique is used to maximize harvest by growing the same crop in an area.
What is a monoculture or monocropping?
400
This sustainable forestry technique involves getting rid of the accumulation of dead biomass on the forest floor to prevent larger wildfires in the future.
What are prescribed/controlled burns?
400
Gasoline leaks from cars, fertilizers from lawns, debris from construction sites, and wastewater from washing cars can contribute to this.
What is urban runoff?
400
This is the highest grade of coal, making it desirable to mine.
What is anthracite?
400
This is the process of restoring land back to its former condition after mining.
What is reclamation?
500
This method of managing pests focuses on minimizing environmental damage as much as possible by shifting away from the use of pesticides.
What is IPM?
500
This method of reforestation is a type of monoculture planted for economic purposes that is used to meet global timber demands.
What are tree plantations?
500
These are TWO solutions to help mitigate and reduce issues caused by urban runoff.
What are permeable/pervious pavement, planting of trees, increased use of public transportation (to combat private vehicles car washes and gasoline leaks), building up instead of out (don't need to use as much land), etc.?
500
This can occur when fish grown in an aquaculture escape and interact with wild fish.
What are transmission/spread of diseases, breed, ecosystem disruptions, increased competition for food and resources, etc.?
500
This phenomenon occurs when inefficient irrigation techniques lead to excess water evaporation leaving the soil with a higher concentration of salts reducing plant growth.
What is soil salinization?
