AP Human Geography Unit Review

5 Themes of Geography

  • Location

    • Absolute Location: Specific coordinates (latitude and longitude).
    • Relative Location: Position of a place in relation to another place.
  • Place

    • Distinctive physical and human characteristics of an area (e.g., culture, climate, terrain).
  • Human-Environment Interaction

    • Ways humans adapt to and modify the environment (e.g., agriculture, urbanization).
  • Movement

    • Mobility of people, goods, and ideas.
    • Patterns of spatial interaction and connectivity of places.
  • Regions

    • Areas defined by specific criteria or characteristics (e.g., cultural, political, physical).

Physical and Human Geography

  • Physical Geography:

    • Topography: Physical landscape features.
    • Climate: Patterns of weather, classified via the Koppen system.
    • Flora and Fauna: Plant and animal life.
    • Soil Types: Different soil characteristics and qualities.
  • Human Geography:

    • Culture: Beliefs, practices, social norms of people.
    • Population: Patterns, distributions, and demographic characteristics.
    • Economic Systems: Structures and activities related to economies.
    • Political Systems: Governance and political organization.
    • Urban Areas: Characteristics of cities and metropolitan areas.

Map Projections and Distortions

  • Types of Map Projections:

    • Goode’s Homolosine: Interrupts land masses to minimize distortion.
    • Conic Projection: Accurate in distance and direction over small areas.
    • Planar Projection: Accurate at one central point, distorts edges.
    • Mercator Projection: Maintains direction but distorts size, especially near poles.
    • Robinson Projection: Balances size and shape distortions, good for representing global data.
    • Gall-Peters Projection: Accurate size relationships but distorts shapes.
    • Winkel Tripel Projection: Minimizes distortion for shape and area, particularly at the poles.
  • Four Forms of Distortion in Maps:

    • Shape of area may be altered.
    • Direction between points can be distorted.
    • Distance between points may be exaggerated or minimized.
    • Relative size of places may be distorted.

Thematic Maps

  • Isoline Maps:

    • Use lines to show equal values of a variable (e.g., temperature, elevation).
  • Choropleth Maps:

    • Use color or shading to represent data.
  • Graduated Symbol Maps:

    • Symbol size indicates data magnitude.
  • Dot Maps:

    • Each dot represents frequency of a variable.
  • Cartograms:

    • Size of political units represents a data value, altering traditional shape.

Climate Factors (LACEMOPS)

  • Latitude:

    • Distance from the equator affects temperature.
  • Air Masses:

    • Cold air from the north, warm from the tropics.
  • Continentality:

    • Water bodies moderate climate, inland areas experience more extremes.
  • Elevation:

    • Temperature drops 3.5°F per 1,000-foot increase in elevation.
  • Mountain Barriers:

    • Affect precipitation patterns; windward sides wet, leeward sides dry.
  • Ocean Currents:

    • Cold currents bring cool air; warm currents bring moisture.
  • Pressure Cells:

    • High pressure (cold air) and low pressure (warm air) influence weather patterns.

Migration Trends and Patterns

  • Migration Statistics:
    • Women tend to migrate internally.
    • Men often migrate internationally.
    • Most migrants are adults, families are less likely to migrate.
    • Major migration trend: rural to urban areas.
    • Economic factors are primary drivers for migration.

Economic Classifications of Countries

  • Primary: Resource extraction (e.g., agriculture, mining).

  • Secondary: Manufacturing (e.g., factories producing goods).

  • Tertiary: Service sector (e.g., healthcare, education).

  • Quaternary: Knowledge-based services (e.g., IT, research).

  • Categories:

    • MDC: Most Developed Countries (e.g., USA, Canada, Japan).
    • NIC: Newly Industrialized (e.g., Brazil, China).
    • LDC: Least Developed Countries (e.g., Afghanistan, Haiti).

Population and Demographics

  • Demographic Transition Model: Stages of population growth.

    • Stage 1: High birth/death rates, stable population.
    • Stage 2: Declining death rates, high birth rates, rapid growth.
    • Stage 3: Declining birth rates, stable population growth.
    • Stage 4: Low birth/death rates, population possibly shrinking.
    • Stage 5: Decline - very low birth rates, high death rates; aging population issues.
  • Epidemiologic Transition Model:

    • Stage 1: Pestilence and famine.
    • Stage 2: Receding pandemics.
    • Stage 3: Degenerative diseases.
    • Stage 4: Delayed degenerative diseases.
    • Possible Stage 5: Evolution of diseases, resistance issues.

Cultural Geography

  • Language Families: Groups of languages that share a common ancestor.

  • Universalizing vs. Ethnic Religions:

    • Universalizing (e.g., Christianity, Islam) seeks global followers;
    • Ethnic (e.g., Hinduism, Judaism) associated with specific cultural groups.
  • Cultural Diffusion Types:

    • Relocation Diffusion: Spread through migration.
    • Expansion Diffusion: Continuous spread from a node (contagious, hierarchical, stimulus).

Political Geography

  • Types of States:

    • Unitary: Concentrated power, typically in smaller, homogeneous states.
    • Federal: Shared power between levels of government, suitable for diverse nations.
    • Confederal: Loose alliance of independent states.
  • Devolution: Transfer of power from central to regional governments.

  • Gerrymandering: Manipulating electoral district boundaries for political advantage.

  • International Organizations:

    • UN, NATO, EU, OPEC: Various roles in facilitating cooperation, security, and economic collaboration.
