🚜AP Human Geography Previous Exam Prep

Key Concepts and Themes

• Population dynamics involve the study of changes in population size, composition, and distribution over time and space
  • Includes factors such as fertility, mortality, and migration rates
• Demographic transition model describes the stages of population growth that countries go through as they develop economically
  • Consists of four stages: high birth and death rates, declining death rates, declining birth rates, and low birth and death rates
• Population pyramids visually represent the age and sex structure of a population
  • Shape of the pyramid reflects the demographic characteristics and stage in the demographic transition model (Nigeria vs. Japan)
• Malthusian theory suggests that population growth will eventually outpace food production, leading to population checks such as famine and disease
• Epidemiological transition model describes the changes in disease patterns that occur as countries develop
  • Shift from infectious diseases to chronic and degenerative diseases (heart disease, cancer)
• Migration flows, both internal and international, are influenced by push and pull factors
  • Push factors encourage people to leave an area (war, poverty), while pull factors attract people to a new area (job opportunities, better living conditions)
• Urbanization is the process of population concentration in cities and the resulting changes in social and economic structures
  • Rapid urbanization in developing countries often leads to the growth of squatter settlements and informal economies

Geographical Models and Theories

• Von Thünen model explains the spatial organization of agricultural land use around a central market city
  • Concentric rings of different crops based on transportation costs and land rent (perishable crops closer to the city)
• Central Place Theory by Walter Christaller explains the size, number, and distribution of settlements in a region
  • Hierarchical arrangement of settlements based on the goods and services they provide (hamlets, villages, towns, cities)
• Rostow's Stages of Economic Growth model describes the five stages that economies go through during the process of development
  • Traditional society, preconditions for take-off, take-off, drive to maturity, and age of high mass consumption
• Wallerstein's World Systems Theory divides the world into core, periphery, and semi-periphery regions based on their role in the global economy
  • Core regions dominate and exploit the periphery regions through unequal trade relationships
• Heartland-Rimland Theory by Halford Mackinder emphasizes the strategic importance of the Eurasian landmass in global geopolitics
  • Control of the heartland (Central Asia) could lead to world domination
• Gravity model in human geography predicts the interaction between two places based on their population sizes and the distance between them
  • Larger populations and shorter distances lead to greater interaction (trade, migration, communication)
• Tobler's First Law of Geography states that "everything is related to everything else, but near things are more related than distant things"
  • Spatial autocorrelation and the importance of location in geographical analysis

Important Terminology

• Carrying capacity: the maximum population size that an environment can sustain given the available resources
• Ecumene: the permanently inhabited portion of the Earth's surface
• Megalopolis: a large, densely populated urban region formed by the merging of several metropolitan areas (Northeast U.S., Japan's Pacific Coast)
• Gentrification: the process of renovating and improving a neighborhood, often leading to the displacement of lower-income residents by higher-income residents
• Redlining: the discriminatory practice of denying services (such as loans or insurance) to residents of certain areas based on their race or ethnicity
• Gerrymandering: manipulating the boundaries of electoral districts to favor a particular political party or group
• Balkanization: the fragmentation of a region or state into smaller, often hostile, units (former Yugoslavia)
• Lingua franca: a common language used for communication between people with different native languages (English, Swahili)
• Toponymy: the study of place names and their origins, often reflecting cultural, historical, or geographical characteristics
• Diffusion: the spread of ideas, innovations, or cultural traits from one place to another
  • Hierarchical diffusion spreads through urban hierarchy (fashion trends)
  • Contagious diffusion spreads through direct contact (diseases)
  • Stimulus diffusion involves adapting an idea to local conditions (rock music)

Case Studies and Real-World Examples

• The Green Revolution: agricultural technology transfer that increased crop yields in developing countries (Mexico, India)
  • High-yield varieties, irrigation, fertilizers, and pesticides
  • Contributed to population growth and urbanization
• The One Child Policy in China: government policy to limit population growth by restricting couples to one child
  • Led to unintended consequences such as sex-selective abortions and an aging population
• The Aral Sea Disaster: shrinking of the Aral Sea due to irrigation diversions for cotton production in Central Asia
  • Environmental and health impacts on local populations
• The Deforestation of the Amazon Rainforest: clearing of the rainforest for logging, cattle ranching, and agriculture
  • Loss of biodiversity, carbon emissions, and impacts on indigenous communities
• The Refugee Crisis in Syria: mass migration of Syrians fleeing civil war and seeking refuge in neighboring countries and Europe
  • Strain on host countries' resources and political tensions
• The Rust Belt in the United States: decline of manufacturing industries in the Midwest and Northeast regions
  • Deindustrialization, urban decay, and population loss (Detroit, Cleveland)
• The Growth of Megacities in Developing Countries: rapid urbanization and the challenges of managing large urban agglomerations
  • Infrastructure, housing, and service provision (Mumbai, Lagos)

Map Analysis and Interpretation

• Choropleth maps use color or shading to represent data values for different geographic areas
  • Interpreting the legend and identifying spatial patterns (literacy rates by country)
• Dot density maps use dots to show the distribution and concentration of a phenomenon
  • Estimating density and identifying clusters (population distribution in China)
• Proportional symbol maps use symbols of different sizes to represent data values for specific locations
  • Comparing magnitudes and identifying outliers (cities by population size)
• Isoline maps connect points of equal value with lines
  • Identifying gradients and interpolating values (elevation contours, temperature isotherms)
• Cartograms distort the size of geographic areas based on a data value
  • Emphasizing differences and revealing hidden patterns (world map of GDP per capita)
• Mental maps are individual perceptions of the spatial organization of places and regions
  • Reflecting cultural biases and personal experiences (sketch maps of neighborhood)
• Analyzing map projections and their distortions
  • Mercator projection exaggerates size of high-latitude areas
  • Peters projection maintains relative size but distorts shape

Practice Questions and Strategies

• Read the question carefully and identify the key concepts or skills being tested
  • Underline or highlight important information in the prompt
• Analyze any maps, graphs, or charts provided and relate them to the question
  • Look for patterns, trends, or anomalies in the data
• Eliminate answer choices that are clearly incorrect or irrelevant
  • Cross out choices that contradict the information given or your knowledge
• Use process of elimination to narrow down the remaining choices
  • Compare the choices and select the one that best answers the question
• Apply your knowledge of geographical concepts, models, and theories to the question
  • Think about how the concepts relate to the specific scenario or data presented
• Look for key words that signal the type of question being asked
  • "Most likely" or "best explains" indicate a question about causation or inference
  • "Except" or "least likely" indicate a question about exceptions or outliers
• Manage your time effectively during the exam
  • Don't spend too much time on any one question
  • Make an educated guess if you're unsure and move on

Common Pitfalls and Misconceptions

• Confusing correlation with causation
  • Just because two variables are related does not mean that one causes the other (poverty and crime rates)
• Overgeneralizing from limited data or anecdotal evidence
  • Drawing conclusions about a whole population based on a small sample or personal experience
• Ignoring the role of scale in geographical analysis
  • Patterns and processes may differ at local, regional, and global scales (air pollution)
• Assuming that geographical patterns are static and unchanging
  • Regions and places are constantly evolving due to human and environmental factors (deindustrialization, climate change)
• Neglecting the historical context of current geographical issues
  • Present-day conflicts and inequalities often have roots in past events and decisions (colonialism, redlining)
• Overemphasizing the deterministic role of the physical environment
  • Human agency and cultural factors also shape the landscape and spatial patterns (agriculture in the Netherlands)
• Failing to consider the ethical implications of geographical decisions and policies
  • Actions may have unintended consequences or disproportionate impacts on certain groups (dam construction, urban renewal)
