APHUG Units 1-7 Vocabulary Review

Unit 1: Thinking Geographically Geospatial tools and data form the foundation of geographical analysis. A Reference Map provides basic geographic information about an area, including boundaries, landmarks, and physical features. In contrast, a Thematic Map focuses on specific topics such as population distribution, climate, or economic activity. Specialized thematic maps include the Topographic Map, which shows elevation and land contours via lines for hills and valleys; the Isoline Map, which uses continuous lines like isotherms to represent data like temperature or elevation; and the Dot Density Map, which employs dots to show feature concentration. A Choropleth Map uses colors or shading for statistical data across regions, while a Flow Line Map utilizes arrows to indicate the movement of people or goods. The Cartogram Map distorts geographic size or shape to represent variables like population. Map projections also vary: the Robinson Projection minimizes distortion in size, shape, and direction for world displays, whereas the Mercator Projection preserves angles and shapes but significantly distorts land size at high latitudes. Data collection involves Remote Sensing (satellites/aerial photography), GIS (a system for storage and analysis of geospatial data), and GPS (satellite-based navigation for precise location). These tools generate Geospatial Data (coordinates) and Geographical Data (physical and cultural attributes). Spatial concepts include Absolute Distance (physical units like kilometers or miles) and Relative Distance (measured by travel time or cost). Geographers track Distance Decay, where interaction decreases as distance increases, and Time-Space Compression, where technology reduces the perceived distance between places. Environmental theories differ between Environmental Determinism, which claims the environment shapes culture, and Possibilism, which suggests humans adapt and make choices. Geographic scales of analysis range from the Global Scale (transcending country boundaries) to National, Regional (larger than a neighborhood but smaller than a nation), and Local Scales (single community). Finally, regions are classified as Formal (uniform attributes), Functional (centered on a node or focal point), or Perceptual/Vernacular (defined by people's mental images). # Unit 2: Population and Migration Patterns and Processes Population density is measured through Arithmetic Density (total population divided by total land area), Physiological Density (total population divided by arable land, showing pressure on agricultural resources), and Agricultural Density (number of farmers per unit of arable land). Distribution refers to the arrangement of people, while Carrying Capacity is the maximum population an environment can sustainably support. Demographic analysis uses the Sex Ratio ($males ext{ per } 100 ext{ females}$) and Population Pyramids to visualize age and sex composition. Key rates include the Fertility Rate (average children per woman), Mortality Rate (deaths per $1,000$ people), and Infant Mortality Rate (deaths under age one per $1,000$ live births). The Natural Increase Rate ($NIR$) measures growth from birth and death differences, leading to Doubling Time, calculated as the years needed for a population to double. Models like the Demographic Transition Model ($DTM$) track shifts from high to low birth/death rates. Theories on growth include Malthusian Theory (population outstrips food) and Neo-Malthusian Theory (concerns over resource depletion). Governments may use Pronatalist Policies to increase births or Antinatalist Policies to reduce them, often involving Contraception. Migration is governed by Ravenstein’s Laws and factors like Push Factors (negative conditions at home) and Pull Factors (attractive conditions abroad). Migrants face Intervening Obstacles or find Intervening Opportunities. Movement types include Forced Migration (conflict/disaster), Voluntary Migration (choice), Chain Migration (following others), and Step Migration (series of smaller moves). Displaced individuals include Refugees (fled country due to persecution), Internally Displaced Persons (displaced within their own country), and Asylum Seekers (seeking international protection). Economic migration involves Guest Workers and Remittances (money sent home). Large-scale livestock movement is called Transhumance. Developmental categories include More Developed Countries (high industrialization) and Less Developed Countries. # Unit 3: Cultural Patterns and Processes Culture is understood through Ethnocentrism (belief in cultural superiority) or Cultural Relativism (understanding a culture by its own norms). Cultural Appropriation occurs when elements are adopted without respect for their original significance. The Cultural Landscape is the visible human imprint on the land, such as buildings and agriculture, often showing Sequent Occupancy (layers of history from different cultures). Individuals develop a Sense of Place through emotional attachment, while Placemaking involves deliberate urban design to create meaning. Forces within a culture include Centripetal Forces (unifying) and Centrifugal Forces (dividing). Cultural diffusion occurs via Contagious Diffusion (person-to-person), Relocation Diffusion (physical movement), Hierarchical Diffusion (top-down), Reverse Hierarchical Diffusion (bottom-up), or Stimulus Diffusion (underlying idea spreads though specific traits change). Communication is aided by a Lingua Franca (common trade language) and can lead to Creolization (blending into a new hybrid culture). Historically, Colonialism and Imperialism spread cultures through political and military control. Today, cultures experience Cultural Convergence (becoming similar) or Cultural Divergence (becoming distinct). Religions are divided into Universalizing Religions (global appeal) and Ethnic Religions (tied to specific groups). Languages are organized into Language Families and regional Dialects, often originating from a Cultural Hearth. Cultural change involves Acculturation (adopting traits), Assimilation (complete integration/loss of original identity), Syncretism (blending to create something new), and Multiculturalism (coexistence of diverse groups). # Unit 4: Political Patterns and Processes Political entities include the Nation (shared culture/identity), Nation-State (aligned culture and state), Stateless Nation (no independent state), and Multinational State (multiple nations within). Regions within states can be Autonomous or Semi-Autonomous. Sovereignty is a state's independent authority, while Self-Determination is the right of a group to govern itself, often leading to Independence Movements against Colonialism or Imperialism. Neocolonialism describes continued economic domination after independence. Power is expressed through Territoriality (defense of space), Shatterbelts (regions of instability), and Choke Points (strategic maritime passages). Boundaries are categorized as Relic (no longer functional), Superimposed (forced by outside powers), Subsequent (evolving with culture), Antecedent (existing before cultural development), Geometric (straight lines), or Consequent (accommodating cultural differences). Conflict zones may have a Demilitarized Zone ($DMZ$). Maritime Boundaries and the Law of the Sea regulate ocean use. Internal governance involves Voting Districts, which undergo Redistricting to reflect population changes, sometimes leading to Gerrymandering (manipulation for political gain). States are organized as Federal (shared power) or Unitary (centralized power). Political instability can result from Devolution (transfer of power downwards), Ethnic Separatism, Ethnic Cleansing, Terrorism, or Irredentism (claiming "rightful" territory). Cooperation leads to Supranationalism (e.g., European Union), which benefits from Economies of Scale and Trade Agreements. Identity-based cohesion includes Ethnonationalism and general Cultural Cohesion. # Unit 5: Agriculture and Rural Land-Use Patterns and Processes Farming ranges from Intensive (high input/labor, e.g., Market Gardening, Plantation Agriculture, Mixed Crop/Livestock) to Extensive (low input, e.g., Shifting Cultivation, Nomadic Herding, Ranching). Rural patterns include Clustered, Linear, or Dispersed Settlements. Land surveying systems include Metes and Bounds (natural features), Township and Range (grid), and Long Lot (river/road access). Historical shifts began with Domestication and the Fertile Crescent, followed by the Columbian Exchange. The Second Agricultural Revolution brought 18th-century mechanization, and the Green Revolution in the mid-20th century introduced high-yielding varieties and chemicals. Modern agriculture includes Subsistence Farming (for the family) and Commercial Farming (for market). Agribusiness involves the Commodity Chain and Economies of Scale. Land value is explained by Bid-Rent Theory (proximity to urban centers). The Von Thunen Model uses transportation costs to explain the spatial distribution of crops. Sustainability issues include Desertification, Soil Salinization (from irrigation), and the impacts of Slash and Burn. Techniques like Terracing manage hilly terrain. Modern developments include Biotechnology, GMOs, Urban Farming, and Value-Added Specialty Crops. Organic Farming avoids synthetic chemicals to address Food Insecurity and the problem of Food Deserts (areas lacking nutritious food). # Unit 6: Cities and Urban Land-Use Patterns and Processes Urbanization and Suburbanization involve shifts in population concentration. A city's Site is its physical attributes, while its Situation is its relative location. Large urban centers include Megacities (>10 ext{ million}) and Metacities (>20 ext{ million}). Urban expansion results in Sprawl, Edge Cities (suburban business hubs), Exurbs, or Boomburbs (fast-growing suburbs). A World City serves as a global financial and cultural hub, driven by Globalization and Interdependence. Spatial theories include Central Place Theory (service distribution), the Rank-Size Rule (the $n ext{-th}$ largest city is $1/n$ the size of the largest), and the Primate City (more than double the next largest). Urban models include Concentric Zone (rings), Sector (wedges), Multiple Nuclei (multiple centers), and Galactic City (decentralized/automobile-dependent). Housing varies by density (Low, Medium, High). Infrastructure supports society, while Zoning and Mixed-Land Use regulate development. Planning movements like Smart-Growth, New Urbanism (walkability), and Greenbelts aim for sustainability, as seen in Slow-Growth Cities. Data is analyzed as Quantitative (numerical) or Qualitative (descriptive). Social challenges include Redlining (lending discrimination), Blockbusting (panic selling), Disamenity Zones (extreme poverty), Squatter Settlements (illegal housing), and Gentrification (displacement of low-income residents). Environmental impacts are measured via the Ecological Footprint and the presence of Brownfields (contaminated industrial sites). # Unit 7: Industrial and Economic Development Patterns and Processes The transition to industrialization began with the Industrial Revolution. Economies are divided into the Primary Sector (raw materials), Secondary (manufacturing), Tertiary (services), Quaternary (knowledge/IT), and Quinary (high-level leadership). Industrial location is influenced by Break-of-Bulk Points and the Least Cost Theory. Globally, countries are categorized by World System Theory into Core (highly developed), Semi-Periphery (intermediate), and Periphery (dependent). Economic metrics include $GDP$, $GNP$, and $GNI$. The formal economy is regulated, while the Informal Economy is not. Development is measured by the Gender Inequality Index ($GII$) and the Human Development Index ($HDI$). Theories like the Stages of Economic Growth and Dependency Theory explain progress or stagnation, including Commodity Dependence on primary exports. Cooperation occurs via Complementary Advantage and Comparative Advantage (lower opportunity cost). Neoliberal Policies promote free markets and Trade Agreements (e.g., WTO, EU, OPEC, IMF). Industry strategies include Outsourcing, creating Special Economic Zones ($SEZ$) or Export-Processing Zones ($EPZ$), and Agglomeration. Just-In-Time Delivery minimizes inventory costs. Global goals include Sustainable Development and Ecotourism for conservation.", "title": "APHUG Unit 1-7 Vocabulary & Comprehensive Study Guide"}
