Geography Exam Preparation Notes

Introduction to Maps

  • Types of Maps:
    • Reference Maps: Political & Physical
    • Thematic Maps: Communications tools showing human activity distribution (e.g., Cartogram, Choropleth, Dot Density)
  • Geographic Information System (GIS): Captures, stores, checks, and displays geographic data.
  • GPS (Geographic Positioning System): Uses satellites to pinpoint locations.
  • Remote Sensing: Taking Earth's surface images from satellites/airplanes.
  • Spatial Concepts:
    • Absolute vs. Relative Location
    • Patterns: Clustering, Dispersal, Elevation
  • Distance Decay: Effect of distance on interaction.
  • Time-Space Compression: Increased connectivity despite distance.

Human-Environmental Interaction

  • Sustainability: Balance between meeting present and future needs.
  • Natural Resources: Essential physical materials humans need.
  • Scales of Analysis: Global, Regional, National, State, Local.

Population Distribution

  • Key Concepts:
    • Carrying Capacity: Maximum population supported by the environment.
    • Overpopulation: Insufficient resources for the population.
    • Population Density Methods: Arithmetic, Physiological, Agricultural.

Population Composition

  • Population Pyramid: Graph showing age and sex structure.
  • Demography: Study of populations.
  • Crude Birth/Death Rate: Births/deaths per 1,000 people.
  • Fertility Measures: TFR, Infant Mortality Rate (IMR).

Demographic Transition Model (DTM)

  • Stages:
    1. Pestilence & Famine
    2. Receding Pandemics
    3. Degenerative Diseases
    4. Delayed Degenerative Diseases

Migration

  • Push/Pull Factors:
    • Push: Negative conditions prompting departure (e.g., no jobs).
    • Pull: Positive conditions attracting migrants (e.g., job opportunities).
  • Types of Migration: Internal, International, Voluntary, Forced.

Culture

  • Characteristics of Culture: Material (tools, housing) vs. Nonmaterial (beliefs, traditions).
  • Types of Cultural Diffusion:
    • Relocation, Expansion (Contagious, Hierarchical, Stimulus).

Political Geography

  • State vs. Nation: States have defined boundaries; nations are cultural groups.
  • Types of Boundaries: Geometric, Physical, Cultural.

Urbanization & Sustainability

  • Urban Models: Concentric Zone, Sector, Multiple Nuclei.
  • Urban Challenges: Displacement, segregation, gentrification.

Industrial Revolution

  • Impact on Development: Growth in machine use changes production and society.
  • Economic Sectors: Primary, Secondary, Tertiary, Quaternary.

Sustainable Development

  • Principles: Meeting present needs while ensuring future resource availability.
  • Sustainable Practices: Ecotourism, UN's Sustainable Development Goals.
