100
refers to a city landscape
What is urban
100
a formal name for trash from homes/businesses
What is municipal solid waste
100
the single repeating unit of a polymer
What is a monomer
100
examples of land use, land cover and a land resource
What is - land use: farming, mining, manufacturing, retail, living, - land cover: parking lot, grassland, forest, - land resources: corn, grains, fossil fuels, minerals
100
the country - - farmland/forests
What is rural
200
the spread of poorly planned, low density urban development over rural land
What is urban sprawl
200
the two waste management sources where our trash ultimately ends up
What is landfills and incineration
200
the two basic polymer molecular structures
What is linear and branched
200
Celluloid was invented to replace __________ and save _________________.
What is ivory and elephants
200
can be broken down by bacteria
What is biodegradable
300
Three causes of the urban heat island effect
What is - pavement, buildings absorbing/radiating more heat - waste heat from transportation, air conditioning and industry - lack of vegetation
300
three problems associated with waste management
What is - landfills have limited space - there are many hazardous waste materials incorrectly disposed - leading to the creation of leachates - incineration produces emissions into the air and very toxic ash - much of what is thrown away could be recycled or composted
300
illustration of a crosslinked polymer and explanation of how it changes the physical properties of the polymer
What is (refer to illustration on the board) and the resulting polymer is more elastic and generally stronger.
300
Identify three negative impacts on the environment associated with synthetic polymers
What is - not biodegradable - produces a lot of waste - easily air born (plastic bags) often pollute the environment, especially water - consumption/entanglement by wildlife can harm or kill them - if broken down into small pieces become toxic contaminants in the environment that accumulate through the food chain - BPA in some plastics is an endocrine disruptor
300
property or parcel of land that is contaminated or potentially contaminated
What is a brownfield
400
Three strategies for reducing the heat island effect, explaining why each reduces the urban heat island effect
What is - planting more trees for shade - green roofs - absorb and use energy instead of radiating - light colored concrete/buiding materials that reflect radiation instead of absorbing it. - encourage public transportation to reduce waste heat
400
four methods/examples of source reduction
What is - buy less - buy products in bulk - purchase more durable products - reuse/repurpose materials instead of throwing them away - rent/share products seldom used
400
compare and contrast natural and synthetic polymers and provide one specific example of each
What is - natural polymers are hydrocarbons found in nature such as protiens, cellulose, silk etc. - synthetic polymers are man-made such as plastic, polyester, vulcanized rubber etc.
400
Description of the events and consequences at Love Canal, one of the US worst environmental disasters
What is - Hooker company buries hazardous waste in deserted canal, land sold to local school board for $1, school and housing developments over waste site, reports of human health concerns from chemical burns/ fumes/miscarriages/birth defects/high cancer rates over two decades, civil protest lead the government to act by evacuating the area relocating affecting families and enacting the Superfund Act.
400
the sequence of the rate of biodegradation of the following materials form quickest to longest. leather jacket orange peel newspaper 100% cotton t-shirt plastic water bottle tin can
What is newspaper, orange peel, t-shirt, leather, tin, plastic
500
The five key principles associated with smart growth develoment
What is - compact, mixed-use development - buildings close to street/accessible - public transportation - pedestrian/ people friendly - public/ green space
500
explanation of how phytoremediation can be used to manage brownfield and Superfund sites
What is the use of plants that are adapted to absorb contaminants into their tissues or prevent the spread of ground contamination. contaminate need to be identified then plants specific to absorbing that contamination should be used as long as they can successfully grow in that environment and do not present too much harm to the environment. Brownfields are properties that are potentially contaminated base on previous land uses. Superfund sites are properties with confirmed contamination requiring remediation
500
Three useful properties of plastics and corresponding applications to society.
What is - lightweight (packaging) - strong and durable (packaging/military/construction materials) - inert/chemically resistant (can hold chemical/hazardous materials) - insulator of heat/electricity (electronics/wiring/coolers) - flexible (tubing/wrapping)
500
Identify three hazardous wastes that can be found in your home and explain how these can be disposed of properly to protect the environment
What is household cleaners, pesticides, herbicides, paints, solvents, oil, gas, appliances/electronics, etc. Some of these can be recycled (oil), donated (paints, pesticides, etc), brought to hazardous waste disposal sites/events
500
identify three problems associated with urban sprawl
What is - loss of rural land - reliance on driving - pollution to rural areas - local climate change
