SAQ Practice · define
Define urbanization.
Key Points for Full Credit
Urbanization = the process by which an increasing proportion of the population comes to live in urban areas
Driven by rural-to-urban migration AND natural population increase in cities
Must include the proportional shift — not just 'when cities grow'
Rubric note: Award 1 point for a complete, accurate definition. Urbanization is the process by which an increasing proportion of a country's population comes to live in urban areas (cities and towns), driven by rural-to-urban migration and natural population increase in cities. Must include: (1) the shift in population distribution from rural to urban, (2) the idea of a process (ongoing change). Simply saying 'when cities grow' misses the proportional shift component.
SAQ Practice · describe
Describe one characteristic of a megacity.
Key Points for Full Credit
Describes a specific characteristic with its implication: extreme density, infrastructure challenges, large informal sector, disproportionate GDP share
Must connect the characteristic to its consequence — not just define megacity as '10 million+'
Rubric note: Award 1 point for a specific, accurate characteristic with enough detail. Megacities are urban agglomerations with populations of 10 million or more. Accept: extreme population density creates intense competition for housing and services; infrastructure challenges — water, sanitation, transportation systems struggle to serve such large populations; megacities typically generate a disproportionate share of their country's GDP; informal settlements are common where formal housing cannot keep up with growth. Must describe a specific characteristic with its implication.
SAQ Practice · explain
Explain how the Burgess concentric zone model describes city structure.
Key Points for Full Credit
Describes rings outward from CBD: Zone 2 (transition/manufacturing), Zone 3 (working-class), Zone 4 (middle-class), Zone 5 (commuter)
Explains the underlying logic: land value competition decreases with distance from CBD
Must explain the logic — not just list the zones
Rubric note: Award 1 point for explaining the model's logic. A complete response explains that Burgess describes cities as concentric rings expanding outward from the CBD: Zone 1 (CBD) — commercial/business core; Zone 2 (transition zone) — older housing, light manufacturing; Zone 3 — working-class housing; Zone 4 — middle-class residential; Zone 5 — commuter zone. The model explains this as the result of land value competition — values decrease with distance from the CBD, so different users occupy different zones based on their ability to pay. Must explain the underlying logic.
SAQ Practice · describe
Describe one cause of suburbanization.
Key Points for Full Credit
Describes a specific cause of suburbanization with enough detail
e.g., Automobile + highway construction enabled commuting from lower-density areas; federal mortgage guarantees made homeownership affordable; white flight
Must identify a specific cause AND explain how it drove suburbanization
Rubric note: Award 1 point for a specific cause with enough detail. Accept: automobile ownership and highway construction enabled commuting from lower-density residential areas; federal mortgage guarantees (FHA, VA loans) after WWII made homeownership affordable for the middle class; white flight — racial integration prompted middle-class white families to relocate to predominantly white suburbs; urban problems (crime, crowding, declining schools) pushed families toward suburbs; lower land costs made larger homes affordable. Must identify a specific cause and explain how it drove suburbanization.
SAQ Practice · explain
Explain how gentrification affects urban neighborhoods.
Key Points for Full Credit
Gentrification → rising property values and rents → existing residents can no longer afford housing → displacement
Must explain the causal chain — not just say gentrification 'changes neighborhoods'
May also note physical improvements and new services as concurrent effects
Rubric note: Award 1 point for explaining a causal mechanism. A complete response explains that gentrification — the influx of higher-income residents into lower-income neighborhoods — causes rising property values and rents, which makes housing unaffordable for existing residents, leading to their displacement. Simultaneously, the neighborhood receives investment in physical improvements, new businesses, and services. Must explain the mechanism (rising values → displacement) not just describe that gentrification changes neighborhoods.
SAQ Practice · describe
Describe one impact of urban sprawl.
Key Points for Full Credit
Describes a specific impact of urban sprawl: automobile dependence, loss of agricultural land, infrastructure costs, traffic congestion, health consequences
Explains the mechanism behind that impact
e.g., Low-density sprawl makes walking and transit impractical → car trips increase → more emissions
Rubric note: Award 1 point for a specific impact with enough detail. Accept: increased automobile dependence — low-density sprawl makes walking and transit impractical, increasing car trips, fuel consumption, and greenhouse gas emissions; loss of agricultural land and open space as development expands outward; infrastructure costs — extending roads, water, sewer, and electricity to low-density areas is expensive per resident; traffic congestion as workers commute longer distances; reduced physical activity and public health consequences of car-dependent environments. Must describe a specific impact with its mechanism.
SAQ Practice · explain
Explain how transportation infrastructure shapes urban form.
Key Points for Full Credit
Identifies a specific type of transportation infrastructure
Explains HOW it shapes where and how urban development occurs
e.g., Highway interchanges attract commercial development → edge cities; rail transit concentrates development at stations
Must explain the mechanism causally
Rubric note: Award 1 point for explaining a causal mechanism connecting transportation to urban development patterns. A complete response identifies a specific type of transportation infrastructure and explains HOW it shapes where and how urban development occurs — e.g., rail transit lines concentrate development at stations, creating dense nodes along corridors; highway interchanges attract commercial and industrial development; the automobile and highway system enabled low-density suburban sprawl; infrastructure deficits force residents in developing cities into informal settlements without services. Must explain the mechanism causally.
SAQ Practice · describe
Describe one way housing discrimination has shaped urban geography.
Key Points for Full Credit
Describes a specific discriminatory practice: redlining, racial covenants, blockbusting, or exclusionary zoning
Must describe the mechanism AND its geographic outcome
Rubric note: Award 1 point for a specific, accurate example with enough detail. Accept: redlining — banks and federal agencies designated minority neighborhoods as high-risk and denied mortgages or insurance, preventing wealth accumulation and concentrating poverty in these areas; racial covenants prevented sale to non-white buyers; blockbusting manipulated white homeowners into selling cheaply; exclusionary zoning — single-family-only zoning effectively excludes lower-income populations from wealthy suburbs. Must describe the mechanism and its geographic consequence.
SAQ Practice · explain
Explain how smart growth principles differ from traditional suburban development.
Key Points for Full Credit
Smart growth: compact, mixed-use, walkable, transit-oriented development
Traditional suburban: low-density, single-use, automobile-dependent
Explains HOW smart growth's design differences reduce car dependence and preserve open space
Must explain the design difference AND why it matters
Rubric note: Award 1 point for explaining a causal mechanism distinguishing the two approaches. A complete response explains that smart growth promotes compact, mixed-use, walkable, transit-oriented development — in contrast to traditional suburban development which is low-density, single-use, and automobile-dependent. Smart growth's higher density and transit access reduces car dependence, preserves open space, and makes infrastructure more cost-effective per resident. Must explain HOW smart growth differs in design and why those differences matter for sustainability.
SAQ Practice · describe
Describe one difference between the Hoyt Sector Model and the Burgess Concentric Zone Model.
Key Points for Full Credit
Burgess: concentric rings radiating uniformly from the CBD (assumes equal accessibility in all directions)
Hoyt: wedge-shaped sectors extending along transportation corridors; high-income housing clusters along preferred routes
Key difference: Hoyt incorporates the directional influence of transportation axes
Must contrast both models specifically — not just describe one
Rubric note: Award 1 point for a specific, accurate difference with enough detail. The key difference is the shape of land use zones: Burgess describes concentric rings radiating uniformly from the CBD; Hoyt describes wedge-shaped sectors extending outward from the CBD along transportation corridors, with high-income housing clustering along the most attractive routes. This means Hoyt incorporates the directional influence of transportation axes, while Burgess assumes uniform accessibility in all directions. Must contrast both models specifically.
