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.
