AP Human Geography In-depth Notes
BASIC HUMAN GEOGRAPHY - UNIT I
- Longitude & Latitude:
- Longitude:
- Angular distance in degrees, minutes, and seconds, east or west of the Prime Meridian.
- Graphically represented as vertical lines (meridians).
- Latitude:
- Angular distance in degrees, minutes, and seconds, north or south of the Equator.
- Graphically represented as horizontal lines (parallels).
- Absolute Location:
- Exact position of an item on Earth's surface expressed by coordinates.
- Example: Chicago at 41°53'N, 87°38'W.
- Relative Location:
- Location described in relation to other locations.
- Example: "Chicago is south of Milwaukee."
- Site vs. Situation:
- Site refers to internal physical characteristics (e.g., resources, climate).
- Situation refers to external locational attributes; how a location relates to other places.
POPULATION GEOGRAPHY - UNIT II
- Demography: Study of population characteristics and trends.
- Crude Birth Rate (CBR): Births per 1,000 persons.
- Crude Death Rate (CDR): Deaths per 1,000 persons.
- Rate of Natural Increase (RNI):
- RNI=extCBR−extCDR
- Demographic Transition Model (DTM):
- Illustrates transitioning from high birth/death rates to low rates as a country develops. Stages include:
- High Stationary
- Early Expanding
- Late Expanding
- Low Stationary (possibly Stage 5)
- Population Patterns:
- Factors include environment, economy, history, and politics. High density areas: East Asia, South Asia, Southeast Asia, Europe.
CULTURAL GEOGRAPHY - UNIT III
- Cultural Hearth: Origin places of civilizations, e.g., Nile River Valley, Mesopotamia.
- Language Families:
- Groups of languages with common ancestral language; the Indo-European family is predominant.
- Types of Diffusion:
- Contagious, Hierarchical, and Stimulus diffusion methods impact how cultures spread.
- Ethnicity vs. Race:
- Ethnicity relates to cultural identity (common ancestry, language, and cultural traits).
- Race is based on physical characteristics. Racism arises from hostility toward specific races.
POLITICAL GEOGRAPHY - UNIT IV
- Nation vs. State vs. Nation-State:
- Nation: a group of people sharing common cultural characteristics.
- State: political entity with defined borders and a governing body.
- Nation-State: a state primarily occupied by one nation (e.g., Japan).
- Geopolitical Theories:
- Heartland by Mackinder, emphasizing control of Eurasia.
- Rimland by Spykman, focusing on coastal areas.
- World Systems Theory by Wallerstein categorizing countries into core, semi-periphery, and periphery.
AGRICULTURAL GEOGRAPHY - UNIT V
- Von Thunen Model:
- Describes agricultural land use based on proximity to cities.
- Zones:
- Dairy and intensive farming (closest)
- Timber and firewood
- Extensive field crops
- Ranching
- Neolithic Revolution: Shift from hunting-gathering to farming led to population growth and social stratification.
- Green Revolution: Innovations in agriculture leading to increased productivity through biotechnology.
ECONOMIC GEOGRAPHY & DEVELOPMENT - UNIT VI
- Types of Economic Activities:
- Primary: Extraction of raw materials (agriculture, mining).
- Secondary: Manufacturing processes (factories).
- Tertiary: Service sector (banking, healthcare).
- Quaternary: Knowledge-based services (IT, education).
- Quinary: High-level decision-making (scientific research).
- Development Indicators:
- HDI considers life expectancy, education, and GDP to measure human development.
- Globalization & Economic Integration: Increased interconnections due to trade, advancements in transport and communication.
URBAN GEOGRAPHY - UNIT VII
- Evolution of Cities: From settlement patterns to modern urban sprawls; major urban hearths include the Nile, Indus, and Yangtze Rivers.
- Urban Models:
- Concentric Zone Model: Class distribution by proximity to CBD.
- Sector Model: Urban development along transportation routes.
- Multiple Nuclei Model: Growth around multiple nodes, not just the CBD.
- Edge Cities: Business and shopping centers outside traditional urban areas.
- Suburbanization: Growth of suburbs leading to changes in urban dynamics.
- Urban Revitalization: Gentrification effects, often leading to residential displacement.
MISCELLANEOUS: CULTURAL ECOLOGY, ENVIRONMENTAL ISSUES, GLOBALIZATION
- Environmental Determinism vs. Possibilism:
- Determinism suggests that the physical environment shapes culture.
- Possibilism argues humans adapt choices within their environment.
- Current Environmental Issues: Rising pollution rates due to urbanization; global warming and its impacts on weather and displacement events.
