AP Human Geography Guide

5 Themes of Geography

  • Location: Relative and absolute (latitude and longitude).
  • Place: Distinct physical/human characteristics of an area.
  • Human-Environment Interaction: How humans interact with their environment.
  • Movement: Mobility of individuals, goods, and ideas.
  • Regions: Areas defined by one or more distinct characteristics.

Physical and Human Geography

  • Physical Geography: Topography, Climate (Koppen), Flora and Fauna, Soil.
  • Human Geography: Culture, Population, Economic, Political, Urban Agriculture.

4 Forms of Distortion on Maps

  • Shape of the area.
  • Direction between points.
  • Distance between points.
  • Relative size of the place.

Thematic Maps

  • Isoline Maps: Lines of equal value (e.g., elevation).
  • Choropleth Maps: Shading patterns or colors to show data.
  • Graduated Symbol Map: Symbol size proportional to data intensity.
  • Dot Map: Dots represent data frequency.
  • Cartogram: Size of political unit displays data value.

LACEMOPS Climate Acronym

  • L: Latitude.
  • A: Air Masses.
  • C: Continentality.
  • E: Elevation.
  • M: Mountain Barriers.
  • O: Ocean Currents.
  • P: Pressure Cells.
  • S: Storms.

Migration

  • Women more migratory within countries; Men more between countries.
  • Economic reasons are a major cause of migration.
  • Migration increases with commerce and transportation improvements.
  • Rural to urban migration is a major stream.

Map Projections

  • Goodes Interrupted: Minimizes distortion; interrupts Antarctica and oceans.
  • Conic: Accurate for distance/direction in small zones.
  • Mercator: Maintains direction; distorts shape/size, used for sea travel.
  • Robinson: Balanced distortion, landforms shown correctly.
  • Gall-Peters: Accurate landmass size; distorted shapes.
  • Fuller Projection: Accurate size and shape; no cardinal directions.
  • Winkel Tripel: Rounder shape; distortion near poles.

Economic Terms

  • Primary Countries: Extract resources.
  • Secondary Countries: Manufacture/refine products.
  • Tertiary Countries: Provide services.
  • Quaternary Countries: Information and management services.
  • MDC: Most Developed Countries.
  • NIC: Newly Industrialized Countries.
  • LDC: Least Developed Countries.

Unit 1 Vocabulary

  • Cartography: Science of mapmaking.
  • Scale: Relation of feature size to map size.
  • Scale of Analysis: Data organization on maps.
  • Distance: Absolute (quantitative) and relative (qualitative).
  • Regions: Formal, Functional, Perceptual.
  • Culture: Beliefs, values, materials.
  • Diffusion: Relocation, Expansion (Hierarchical, Contagious, Stimulus).

Theories and Models

  • Wallerstein’s Core-Periphery Model: Core, Semi-periphery, Peripheral countries.
  • Rostow’s Stages of Development: 5 stages from traditional society to mass consumption.

Environmental Concepts

  • Space-Time Compression: Increased connectivity reducing distance decay.
  • Pillars of Sustainability: Environment, Economy, Society.
  • Environmental Determinism vs. Possibilism: Debate on influence of environment vs. human control.

Demographic Transition Model (DTM)

  • Stage 1: Low growth.
  • Stage 2: High growth.
  • Stage 3: Moderate growth.
  • Stage 4: Low growth.
  • Stage 5 (possible): Decline.

Epidemiologic Transition Model (ETM)

  • Stages representing shifts in disease patterns and health improvements.

Cultural Geography

  • Differences between Folk and Popular culture.
  • Diffusion barriers: Distance, age, language, religion, politics, etc.

Language and Religion

  • Language Families: Indo-European, Sino-Tibetan, etc.
  • Universalizing Religions: Christianity, Islam, Buddhism.
  • Ethnic Religions: Hinduism, Judaism, etc.

This guide should serve as a comprehensive overview of key concepts in AP Human Geography, encompassing physical and human geography, map projections, economic terms, theories, demographic models, and cultural geography.
