Classroom Rules and Expectations

• General Classroom Conduct:

  • Be in the classroom and ready to start when the bell rings; remain seated until dismissal.

  • Maintain a positive attitude and active engagement daily (no heads down on desks, talking while others speak, or grooming during instructional time).

  • Show respect for peers, teachers, and instructional materials.

  • Focus exclusively on AP Human Geography during class time and ask questions when help is needed.

• Cell Phone Policy (SoWashCo / East Ridge High School Policy):

  • Cell phones are prohibited in classrooms and instructional spaces, including the media center, from bell to bell. Use is permitted only during passing time, lunch, and before or after school.

  • First Offense: Staff member confiscates the device for the class period, returning it at the dismissal bell. The teacher notifies the parent/guardian and logs the contact in Infinite Campus.

  • Second Offense: Device is confiscated and turned in to an administrator for the hour; a behavior referral is submitted. An assistant principal follows up with the student and parent/guardian. The student retrieves the phone at the end of the hour.

  • Third Offense: Device is confiscated and turned in to an administrator for the rest of the school day; a behavior referral is submitted. An assistant principal contacts the parent/guardian. The student retrieves the phone at the end of the school day.

  • Fourth Offense: Device is confiscated and turned in to an administrator for the rest of the school day; a behavior referral is submitted. An assistant principal follows up, and a parent/guardian must physically pick up the device.

  • Refusal to Surrender Device: Refusal is treated as insubordination, resulting in administrative intervention and potential consequences up to suspension for chronic violations.

School Check-In / Check-Out Procedures

• All students (including online students arriving or leaving) must check in and out at designated building kiosks using their Student IDs.

• Approved Entrances/Exits: Main Entrance and Athletics Entrance.

• Entering, exiting, or propping non-approved doors is a security violation subject to disciplinary action.

District AI Use Framework (District 833 Guidelines)

• Academic Dishonesty Threshold: Any work created or significantly altered with AI and submitted as a student's own original work without proper citation violates building policy.

• Four Levels of AI Usage:

  1. AI Free (Intentional Human Learning): No AI tools permitted. Work must rely entirely on individual student knowledge.

  2. AI Assisted (AI as Support): AI allowed for specific preliminary tasks (brainstorming, planning, feedback, spell-checking). Students must demonstrate mastery independently, cite AI use, and explain how it was utilized.

  3. AI Enhanced (AI as Part of Task): AI used interactively throughout to refine, polish, or structure work. Human oversight is required to verify accuracy, fairness, and originality, accompanied by full citation.

  4. AI Empowered (AI for Enrichment): AI used to complete advanced tasks beyond classroom scope. Human oversight and explicit citation/explanation are mandatory.

Academic Integrity and Cheating Policy

• Definition of Violations:

  • Submitting another's work (including internet sources) as one's own.

  • Providing completed work to another student.

  • Plagiarism (using another person's ideas, phrasing, or structure without attribution).

  • Possession of unauthorized exam materials or copies of tests.

  • Using notes or electronic devices during an assessment.

  • Communicating during quizzes or tests.

  • Violating announced test procedures.

Assessment Structure and Grading Scale

• Formative Assessments ($10\%$ of Total Grade):

  • Includes Key Issue reading guides, map assignments, World Geography practice tasks, and short projects.

  • Demonstrates progress toward unit learning objectives.

  • Redo opportunity available only for work scoring below $50\%$.

• Summative Assessments ($90\%$ of Total Grade):

  • Includes end-of-unit Multiple Choice Questions (MCQ), Free Response Questions (FRQs), and comprehensive chapter quizzes.

  • Retake Policy: Summative retakes permit scores up to $100\%$ if taken within 2 weeks of the original test date (1 opportunity allowed). Test corrections or FRQ rewrites can earn up to $85\%$ upon completion of required remediation.

Introduction to Maps and Spatial Thinking

Definition and Scope of Geography

• Etymology: Derived from Greek—Geo ("Earth") and Graphy ("to write").

• Core Philosophical Questions: Geography asks "Where" (locational description of spatial patterns) and "Why There" (explanation of the underlying processes creating spatial patterns).

• Physical vs. Human Geography:

  • Physical Geography: Study of natural physical processes across Earth's four spheres (lithosphere, atmosphere, hydrosphere, biosphere)—focuses on where physical features occur.

  • Human (Cultural) Geography: Study of the spatial differentiation and organization of human activity across Earth's surface—focuses on why human activity occurs where it does.

  • Spatial Data: Approximately $80\%$ of all modern information contains a spatial component.

Maps as the Primary Tool of Geographers

• Map Definition: A two-dimensional or flat scale model of Earth's surface, or a portion of it. It serves as an abstract, scaled representation of spatial phenomena.

• Cartography: The science and art of mapmaking.

• Two Primary Functions of Maps:

  1. Reference Tool: Used to locate objects, navigate from point A to point B, and identify absolute and relative locations.

  2. Communication Tool: Used to illustrate the spatial distribution of human activities or physical features and uncover spatial relationships.

Historical Evolution of Mapmaking

• Marshall Islands Stick Charts: Ancient Polynesian navigation devices constructed from palm strips (representing wave swells) and shells (representing island locations).

• Eratosthenes ($276\text{--}194\text{ B.C.}$): Coined the term geography, calculated Earth's circumference with high accuracy, and created one of the earliest world maps.

• Ptolemy (c. $150\text{ C.E.}$): Produced an 8-volume Geography, established early principles of map grid systems, and mapped the known world around the Mediterranean and Indian Ocean during the Roman Empire.

• Non-European Mapmaking Contributions:

  • China: Yu Gong (earliest economic/geographical chapter in Chinese literature, 5th century B.C.); Pei Xiu (father of Chinese cartography, produced an elaborate map of China in 267 C.E.).

  • Islamic World: Muhammad al-Idrisi (1154 C.E., built upon Ptolemy's work to create an advanced world map and geography text); Ibn Battuta (14th century, mapped extensive travels across North Africa, Southern Europe, and Asia covering over $120,000\text{ km}$).

• Age of Exploration (15th–16th Centuries): Mapmaking shifted toward global navigation; Abraham Ortelius (1571) created one of the first modern atlases showing the full extent of the Western Hemisphere and Antarctica.

Modern Map Types and Spatial Representation

• Reference Maps: Designed for locating places and geographic features.

  • Topographic Maps: Display contour lines to represent physical elevation alongside human-made infrastructure.

• Thematic Maps: Display statistical data to illustrate spatial distributions and relationships.

  • Choropleth Maps: Use shading, color intensity, or pattern variations to represent average values or percentages of a variable within predefined geographic units (e.g., states, counties, census tracts).

• Cartograms: Intentionally scale the geometry of map areas proportional to a specific quantitative variable (such as population size or total sales volume) rather than physical land area.

• Dot Matrix (Dot Density) Maps: Use individual dots to represent a specific frequency or quantity of a feature occurring within a region.

  • Data Sources: Thematic and reference maps rely on sources like the United States Census, which gathers demographic, housing, and socioeconomic data every 10 years.

Geospatial Technologies and Geographic Data

Contemporary Analytic Geospatial Tools

• Global Positioning System (GPS):

  • A satellite-based navigation system that determines the precise mathematical location (latitude, longitude, elevation) of an object on Earth.

  • Three System Components:

  1. Satellites placed in predetermined orbits ($24$ operational satellites in the U.S. constellation).

  2. Tracking and monitoring ground stations.

  3. Mobile receivers that calculate distance from at least $4$ satellites simultaneously to triangulate precise positions.

  • Applications: Turn-by-turn vehicle routing, aviation/maritime navigation, smart device geotagging.

• Geographic Information System (GIS):

  • A computer software system designed to capture, store, query, analyze, and display spatial data.

  • Data is organized into independent layers (e.g., elevation, water bodies, road network, parcel boundaries, zoning).

  • Data Formats:

  • Vector Data: Consists of explicit points (cities, stops), lines (highways, rivers), and polygons (county borders).

  • Raster Data: Consists of a grid of fine pixels, such as satellite imagery or aerial photographs.

  • Mashup: The integration of multiple distinct GIS data layers from different sources into a single interactive map overlay.

• Photogrammetry:

  • The science of taking reliable measurements through aerial images captured by aircraft or unmanned aerial vehicles (drones) to build detailed 3D spatial models.

• Remote Sensing:

  • The acquisition of data about Earth's surface from sensors mounted on satellites, spacecraft, or high-altitude balloons.

  • Measures reflected electromagnetic radiation (e.g., infrared, visible light) to track land use, urbanization, deforestation, glacier retreat, and agricultural crop health.

• Volunteered Geographic Information (VGI):

  • Creation and assembly of geographic data contributed voluntarily by individuals (e.g., crowdsourced mapping, Google Street View image contributions, open-source mapping projects).

Quantitative vs. Qualitative Geographic Data

• Quantitative Data: Information expressed numerically, statistically, or mathematically (e.g., census counts, income figures, density calculations, precipitation measurements).

• Qualitative Data: Descriptive, narrative information capturing human perception, experience, or cultural contexts (e.g., field observations, interviews, travel journals, policy text analyses, ground photos).

Map Scale, Projections, and Grid Systems

Concepts of Scale

• Map Scale: The direct mathematical relationship between the measurement of an object on a map and its actual length on Earth's surface.

  • Three Modes of Map Scale Representation:

  1. Ratio / Fractional Scale: Expressed as a mathematical ratio (e.g., $1:24,000$ or $\frac{1}{24,000}$), meaning $1\text{ unit}$ on the map represents $24,000\text{ units}$ on the ground.

  2. Written Scale: Expressed in words (e.g., $1\text{ inch equals }1\text{ mile}$).

  3. Graphic / Bar Scale: A visual line segment marked with physical ground distance metrics.

  • Large Scale vs. Small Scale:

  • Large-Scale Maps: Show a small physical area with a high level of close-up detail (e.g., $1:10,000$ view of a city block).

  • Small-Scale Maps: Show a vast physical area with low detail and generalized features (e.g., $1:10,000,000$ view of a continent).

• Geographic Scale (Scale of Analysis): The spatial tier at which a geographer analyzes data—Global, Regional, National, State, County, or Local/Neighborhood. Changing the scale of analysis frequently alters the observed spatial patterns.

Map Projections and Systematic Distortion

• Projection: The mathematical method of transferring the spherical, 3D surface of Earth onto a 2D flat surface.

• The Four Properties of Map Distortion (All flat maps contain distortion in at least one of these):

  1. Shape: Features can appear stretched or squished.

  2. Distance: Spacing between two points can become elongated or compressed.

  3. Relative Size (Area): One landmass can look disproportionately larger or smaller than another.

  4. Direction: Compass bearings between points can become curved or inaccurate.

Major Map Projections

• Mercator Projection:

  • Characteristics: Rectangular grid with straight latitude and longitude lines intersecting at $90^\natural$ right angles.

  • Advantages: Preserves true direction and precise angles; ideal for sea navigation.

  • Disadvantages: Extreme area distortion near the North and South Poles (e.g., Greenland appears larger than South America, despite South America being roughly 8 times larger in reality).

• Gall-Peters Projection:

  • Characteristics: Equal-area rectangular projection.

  • Advantages: Preserves accurate relative land mass size.

  • Disadvantages: Significantly distorts shape; landmasses appear vertically stretched and elongated near the equator.

• Robinson Projection:

  • Characteristics: Curved outer meridians with flat horizontal polar lines.

  • Advantages: Visually balanced ("globelike"); distributes minor distortion across shape, size, distance, and direction.

  • Disadvantages: Area near extreme poles is severely flattened and distorted.

• Azimuthal (Polar / Zenithal) Projection:

  • Characteristics: Formed by projecting Earth onto a flat plane touching a single focus point (often one of the poles).

  • Advantages: Preserves precise directions and distances outward from the central focal point.

  • Disadvantages: Can display only one hemisphere ($50\%$ of Earth) at a time; severe distortion occurs toward the outer edges.

• Goode's Homolosine Projection:

  • Characteristics: Interrupted, equal-area projection resembling peeled orange segments.

  • Advantages: Minimizes size and shape distortion across continental landmasses.

  • Disadvantages: Interrupts oceans, making distance measurements across water bodies inaccurate.

The Geographic Grid and Absolute Location

• Meridians (Lines of Longitude):

  • Vertical arcs drawn north-south between the North and South Poles.

  • All meridians are of equal length and converge at the poles.

  • Measured from $0^\natural$ (Prime Meridian, passing through the Royal Observatory in Greenwich, England) to $180^\natural$ East or West.

• Parallels (Lines of Latitude):

  • Horizontal circles drawn east-west parallel to the Equator at right angles to meridians.

  • Measured from $0^\natural$ (Equator) to $90^\natural\text{ North}$ (North Pole) or $90^\natural\text{ South}$ (South Pole).

  • Major Key Parallels: Tropic of Cancer ($23.5^\natural\text{ N}$), Tropic of Capricorn ($23.5^\natural\text{ S}$).

• Subdivisions of Degrees: Each degree ($^\natural$) is divided into $60\text{ minutes}$ ($'$), and each minute is divided into $60\text{ seconds}$ ($''$) for exact coordinate pinpointing (e.g., Denver Capitol: $39^\natural 42' 2''\text{ N}, 104^\natural 59' 04''\text{ W}$).

Global Time Zones

• Mathematical Calculation:

  • Earth rotates $360^\natural$ of longitude in $24\text{ hours}$.

  • $\frac{360^\natural}{24\text{ hours}} = 15^\natural\text{ of longitude per hour}$. Every $15^\natural$ band equals one standard time zone.

• Greenwich Mean Time (GMT):

  • The baseline standard time located along the Prime Meridian ($0^\natural$ longitude).

• International Date Line:

  • Generally located along $180^\natural$ longitude (deviates locally around island borders).

  • Crossing Eastward (toward the Americas): Set clock back 24 hours (gain a day).

  • Crossing Westward (toward Asia): Set clock forward 24 hours (lose a day).

• Standard Time Zones in North America:

  • Eastern ($-5\text{ h}$ GMT), Central ($-6\text{ h}$ GMT), Mountain ($-7\text{ h}$ GMT), Pacific ($-8\text{ h}$ GMT), Alaska ($-9\text{ h}$ GMT), Hawaii-Aleutian ($-10\text{ h}$ GMT), Atlantic ($-4\text{ h}$ GMT, Canada).

Spatial Concepts: Place and Region

Characterizing Place

• Place: A specific point on Earth distinguished by particular physical and human characteristics.

• Four Ways to Describe Location:

  1. Absolute Location: Exact mathematical position using coordinate systems (latitude/longitude).

  2. Relative Location: Position of a place relative to other known locations or features.

  3. Toponym: The specific name given to a place on Earth.

  • Derived from prominent figures, religious icons, native features, or settler origins. Examples include Boring, Pity Me, Accident, or the longest place name in New Zealand: Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu.

  1. Site: The internal physical and natural characteristics of a place (climate, water sources, topography, soil quality, vegetation, elevation).

  2. Situation: The external location of a place relative to surrounding physical/human features and transportation networks.

The Concept of Region

• Region: An area on Earth defined by one or more distinctive characteristics across cultural, human, or physical criteria.

• Cultural Landscape: The visible fashioning of a natural environment by a cultural group. Formulated by Carl Sauer: "Culture is the agent, the natural area the medium, the cultural landscape is the result."

Three Primary Types of Regions

1. Formal Region (Uniform / Homogeneous):

   • An area where everyone or everything shares one or more common, distinct characteristics (e.g., shared language, dominant crop, unified state laws, common climate zone).

   • Boundaries are official, precise, and non-debatable.

   • Examples: The State of Montana, the North American Wheat Belt, state-level U.S. presidential voting results.

2. Functional Region (Nodal):

   • An area organized around a focal point or central node, connected by communication, transport, or economic systems.

   • The defining characteristic dominates at the node and decreases in intensity as distance increases (Distance Decay).

   • Examples: A newspaper distribution area, television broadcast range, airline flight networks centered on a hub airport (e.g., Delta Airlines hub in Atlanta), metropolitan transit systems (e.g., D.C. Metrorail).

3. Vernacular Region (Perceptual):

   • An area that people believe exists as part of their cultural identity, informal perceptions, or mental maps.

   • Boundaries are vague, informal, overlapping, and subject to debate.

   • Examples: The American South, the Midwest, the Middle East.

Geographic Meaning of Culture

• Etymology: Originates from Latin cultus ("to care for").

• Two Facets of Cultural Study:

  1. What People Care About: Customary beliefs, values, religion, language, and ethnic identity.

  2. What People Take Care Of: Material traits, production of food, clothing, shelter, technology, and economic wealth.

Spatial Interactions, Distribution, and Diffusion

Scale Interactions: Globalization, Glocalization, and Neolocalism

• Globalization: Processes that involve the entire world and make phenomena global in scope, producing increasingly uniform economic and cultural landscapes.

  • Driven primarily by transnational corporations (TNCs), which research, operate, and market products across multiple countries.

  • Leads to placelessness—the loss of unique local cultural landscapes in favor of standardized corporate appearances (e.g., ubiquitous fast-food franchises and retail chains).

• Glocalization: The adaptation of global-scale products or corporate practices to fit local cultural preferences and societal norms.

  • Example: McDonald's offering non-beef items like the McAloo Tikki, Paneer Wrap, and McCurry Pan in India.

• Neolocalism: A conscious effort by local communities to re-embrace and promote local cultural uniqueness and heritage to counter the homogenizing forces of global corporate culture.

Properties of Spatial Distribution

• Distribution: The arrangement of a feature across space.

• Three Main Properties of Distribution:

  1. Density: The frequency with which a feature occurs within a given unit of land area ($\text{Density} = \frac{\text{Total Quantity}}{\text{Land Area}}$).

  • Arithmetic Density: Total number of objects/people divided by total land area.

  • Physiological Density: Total population divided by total arable (farmable) land area.

  • Agricultural Density: Total number of farmers divided by total arable land area.

  1. Concentration: The extent of a feature's spread over a defined space.

  • Clustered (Aggregated): Features are positioned close together.

  • Dispersed (Scattered): Features are positioned relatively far apart.

  1. Pattern: The geometric arrangement of objects across space.

  • Types: Linear (along roads/rivers), Centralized, Rectangular/Grid (e.g., U.S. Land Ordinance of 1785 township and range grid), or Random.

Spatial Association

• Definition: The degree to which the spatial distribution of one feature matches or correlates with the spatial distribution of another feature.

• Example 1: Spatial correlation in Texas between religious affiliation and alcohol sale laws—areas dominated by Baptist/Methodist churches correlate with "dry" laws, whereas Catholic/Lutheran areas correlate with "wet" laws.

• Example 2: Spatial correlation of cancer mortality rates analyzed across national, state (Maryland), and urban (Baltimore city) scales.

Processes of Spatial Diffusion

• Diffusion: The process by which a feature or idea spreads across space over time from its hearth (node of origin).

Primary Types of Diffusion

1. Relocation Diffusion:

   • The spread of an idea or feature through the physical movement of people from one place to another (e.g., migrants carrying languages, religions, or diseases like HIV/AIDS to new locations).

2. Expansion Diffusion:

   • The spread of a feature from one place to another in an additive process, where total adopters increase.

   • Subtypes:

     • Hierarchical Diffusion: The spread of an idea from authority nodes, key leaders, or major urban centers down to smaller places or less influential individuals (e.g., high-fashion trends, technology releases).

     • Reverse Hierarchical Diffusion: The spread of an idea from rural or small-town origins up to large metropolitan centers (e.g., Walmart's corporate expansion).

     • Contagious Diffusion: The rapid, widespread, person-to-person spread of a characteristic throughout a population without regard to status (e.g., viral videos, infectious diseases).

     • Stimulus Diffusion: The spread of an underlying principle or concept, even though the specific original product fails to diffuse (e.g., competitors adopting smartphone touchscreen concepts).

Spatial Interaction and Connectivity

• Distance Decay: The phenomenon where the interaction between two places diminishes as the distance between them increases.

• Space-Time Compression: The reduction in time it takes for something to reach another place due to technological advancements in transportation and telecommunications.

• Core-Periphery Spatial Model:

  • Core Regions: Advanced economic centers (North America, Western Europe, Japan).

  • Periphery Regions: Developing outer regions supplying raw materials and labor (sub-Saharan Africa, Latin America, parts of Asia).

• Geography of Identity:

  • Behavioral Geography: Examines the psychological drivers behind human spatial actions.

  • Humanistic Geography: Emphasizes individual sensory perceptions and personal feelings about places.

  • Poststructuralist Geography: Analyzes how spatial patterns reflect institutional power structures regarding race, gender, class, and sexuality.

Human-Environment Interaction and Sustainability

Principles of Sustainability

• Sustainability: The utilization of Earth's resources in ways that ensure resource availability for future generations.

The Three Pillars of Sustainability (UN Model)

1. Environment Pillar:

   • Sustainable management of natural systems.

   • Distinguishes Conservation (the sustainable, managed use and maintenance of natural resources to meet human needs) from Preservation (maintaining resources in an untouched state, free from human impact).

2. Economy Pillar:

   • Pricing goods and natural resources based on environmental costs and ecological impacts rather than raw supply and demand.

3. Society Pillar:

   • Adapting societal behaviors, cultural consumer desires, and basic needs (shelter, clothing, food) toward sustainable alternatives.

Earth's Four Physical Systems

• Abiotic Systems (Inorganic / Non-Living Matter):

  1. Atmosphere: Thin layer of gases enveloping Earth ($78\%$ Nitrogen, $21\%$ Oxygen, trace gases).

  2. Hydrosphere: All water present on, under, or above Earth's surface (oceans, ice, lakes, rivers, groundwater).

  3. Lithosphere: Earth's crust and portion of the upper mantle directly beneath the crust.

• Biotic System (Organic / Living Matter):

  4. Biosphere: All living organisms on Earth (plants, animals, microorganisms).

• Ecology: The scientific study of interactions between living organisms and Earth's three abiotic systems.

Environmental Determinism vs. Possibilism

• Environmental Determinism:

  • Formulated in the 19th/early 20th centuries (Alexander von Humboldt, Carl Ritter).

  • Asserts that physical environmental factors (climate, terrain) strictly dictate and determine human culture, social developments, and economic capabilities.

  • Criticism: Widely rejected as oversimplified, Eurocentric, and historically used to justify European colonialism and imperialism.

• Possibilism:

  • Asserts that while the physical environment sets certain broad limits, humans possess the cultural agency, technology, and intelligence to adapt to and modify their environment to create multiple possibilities.

  • Example: Constructing climate-controlled cities in desert environments (e.g., Dubai) or manufacturing sugar from temperate sugar beets when tropical sugarcane is unavailable.

Case Studies in Human Environmental Modification

• The Netherlands (Sustainable Ecosystem Modification):

  • Much of the country lies below sea level.

  • The Dutch constructed a network of dikes and polders (parcels of land reclaimed by pumping water out of flooded areas into canals).

  • Focused on sustainable industrial practices, land reclamation, and reducing greenhouse gas emissions.

• South Florida Everglades (Unsustainable Ecosystem Modification):

  • To control flooding and create agricultural land, the U.S. Army Corps of Engineers channelized the meandering Kissimmee River into a straight, $84\text{ km}$ concrete canal.

  • Consequences: Disrupted natural water filtration, severely polluted Lake Okeechobee with agricultural runoff, destroyed habitats, and depleted freshwater supply to the Everglades ecosystem.
