Major geological processes associated with plate tectonics

Intrusive Igneous LandformsReference tableBatholith · Sill · Dike

Structure	Orientation	Distinguishing Feature
Batholith	Deep large dome	Massive intrusion extending hundreds of square kilometers
Sill	Near horizontal sheet	Intrudes parallel between existing rock layers
Dike	Near vertical sheet	Cools in vertical cracks cutting across rock layers

When you use it

Use when identifying landforms produced by magma cooling and solidifying beneath the surface.

Watch out

Sills lie parallel and horizontal between rock strata, while dikes cut vertically across existing layers.

Plate Boundary TypesReference tableConvergent (Destructive) · Divergent (Constructive) · Transform (Conservative)

Boundary Type	Relative Motion	Crust Effect	Examples
Convergent (Destructive)	Plates move toward each other	Denser crust subducts and melts	Andes, Himalayas, Mariana Islands
Divergent (Constructive)	Plates move away from each other	Rising magma creates new crust	Mid-Atlantic Ridge, East African Rift
Transform (Conservative)	Plates slide past each other laterally	Crust is neither created nor destroyed	San Andreas Fault

When you use it

Use when classifying plate margins, their relative motions, and the landforms produced at their boundaries.

Watch out

Do not confuse transform boundaries with convergent or divergent boundaries. Crust is neither created nor destroyed at transform faults.

Seismic Wave TypesReference tableP waves (Primary) · S waves (Secondary) · Surface waves (Love, Rayleigh)

Wave Type	Category	Vibration Direction	Key Characteristic
P waves (Primary)	Body wave	Parallel to direction of wave travel	Alternately compresses and expands rock
S waves (Secondary)	Body wave	Right angles to direction of wave travel	Follows P waves through the body of Earth
Surface waves (Love, Rayleigh)	Surface wave	Along Earth's surface	Slowest, largest amplitude, causes most destruction

When you use it

Use when comparing the behavior, speed, and pathways of seismic waves produced by earthquakes.

Watch out

Surface waves travel more slowly than body waves, but their larger amplitude makes them the most destructive.

Climate change

Adaptation vs Mitigation StrategiesReference tableMitigation · Adaptation

Strategy	Primary Goal	Key Actions and Examples
Mitigation	Reducing GHG emissions and enhancing carbon sinks	Renewable energy, Reforestation, Carbon capture
Adaptation	Moderating damages and adjusting to climate impacts	Terracing, Irrigation, Crop diversification, Resilient building

When you use it

Use when categorizing policy responses to climate change into cause-reduction measures or impact-adjustment practices.

Watch out

Natural ecosystems perform only autonomous and reactive adaptation. They cannot carry out anticipatory adaptation.

International Climate Agreements TimelineReference table1979 · 1988 · 1997 (Enforced 2005) · +1

Year	Conference or Agreement	Key Milestone or Commitment
1979	First World Climate Conference	Recognized climate change as urgent global problem and created WCP
1988	Toronto Conference	Recommended global framework convention, leading to establishment of IPCC
1997 (Enforced 2005)	Kyoto Protocol	Mandatory targets for developed nations to cut GHG emissions by at least 5 percent below 1990 levels
2015	Paris Agreement	Voluntary national emission reduction targets adopted globally to replace Kyoto framework

When you use it

Use when identifying the chronological sequence, legal nature, and emission targets of major global climate treaties.

Watch out

Kyoto Protocol set mandatory targets strictly for developed countries, while the Paris Agreement relies on voluntary targets for all nations.

Milankovitch CyclesReference tableEccentricity · Precession · Obliquity

Orbital Component	Physical Mechanism	Climatic Consequence
Eccentricity	Changes in the shape of Earth orbit around the sun	Alters seasonal solar radiation intensity
Precession	Wobbling of Earth axis of rotation	Shifts seasonal contrast between hemispheres
Obliquity	Changes in the tilt angle of Earth axis	Modifies temperature contrast between poles and equator

When you use it

Use when explaining natural causes of long term climate change and orbital cycles triggering glacial and interglacial periods.

Watch out

Milankovitch cycles explain multi-thousand-year natural variations, not the rapid warming observed since the mid-twentieth century.

Management of conflict over resources

Causes of Resource ScarcityReference tableDemand-induced · Supply-induced · Structural

Scarcity Type	Primary Mechanism	Key Drivers
Demand-induced	Demand increases while supply remains constant or cannot keep pace	Population growth, higher consumption, new technologies
Supply-induced	Total available supply shrinks or degrades	Environmental degradation, natural variation, infrastructure breakdown
Structural	Unequal resource access among different societal groups	Discriminatory laws, cultural exclusion, poverty, land use tradeoffs

When you use it

Use this table when classifying the specific mechanisms driving renewable resource depletion and scarcity in conflict analysis.

Watch out

Do not confuse structural scarcity with supply-induced scarcity. Structural scarcity occurs because of unfair distribution or social barriers, even when the overall physical supply is sufficient.

Dimensions of Sustainable DevelopmentReference tableEconomic · Environmental · Social

Dimension	Core Principle	Main Objectives
Economic	Sustained production of goods and services	Manageable debt, sectoral balance, avoid agricultural and industrial disruption
Environmental	Maintain a stable and resilient natural resource base	Biodiversity conservation, atmospheric stability, prevent overexploitation
Social	Fairness in distribution and opportunities for all	Gender equity, access to health and education, social justice

When you use it

Use this card to compare the three interdependent pillars of sustainable development and their respective policy targets.

Watch out

Remember that sustainable development requires balancing all three nested dimensions at once, rather than treating environmental protection in isolation from economic and social factors.

Drafted from Grade 12 Geography, pages 63-91, then checked twice before it went up

Drivers of Natural Resource ConflictReference tableResource scarcity · Poor governance · Transboundary pressures

Conflict Driver	Root Mechanism	Manifestation
Resource scarcity	Increasing competition over diminishing renewable resources	Demand, supply, or structural scarcity triggering livelihood disputes
Poor governance	Institutional failure, lack of transparency, and discriminatory rules	Unclear tenure rights, elite capture, unfair burden distribution
Transboundary pressures	Cross-border resource interdependence lacking cooperative frameworks	Upstream versus downstream water disputes, pastoral migration, cross-border pollution

When you use it

Use this card to analyze the primary factors that cause, escalate, or sustain conflicts over renewable natural resources.

Watch out

Conflicts over resources are rarely purely environmental. They interact with broader political, institutional, and security factors.

Population policies programs and the environment

Macroeconomic Indicators of DevelopmentReference tableGross Domestic Product (GDP) · Gross National Product (GNP) · Per-Capita Income · +1

Indicator	Definition	Status in Developing Nations
Gross Domestic Product (GDP)	Total market value of final goods and services produced within a country in a year	Low and dominated by primary agricultural commodities
Gross National Product (GNP)	Total value of goods and services produced in a year including income from abroad	Low and dependent on primary commodity exports
Per-Capita Income	Total national income divided by total population size	Low due to non-diversified primary economies and large populations
Standard of Living	Level of income, comforts, and services available to a society	Low with widespread poverty and inadequate health, water, and schooling

When you use it

Use to define and contrast standard measures of economic performance and human living standards.

Watch out

Per capita income is calculated by dividing national income by total population, not by the size of the labor force alone.

Population and Development TheoriesReference tableMalthusian Theory · Neo-Malthusianism · Ester Boserup · +2

Theorist or Theory	Core Argument	Proposed Mechanism
Malthusian Theory	Food grows linearly (1, 2, 3...) while population grows geometrically (1, 2, 4, 8...)	Preventive checks (moral restraint, late marriage) and positive checks (war, famine, disease)
Neo-Malthusianism	Rapid population growth is the primary driver of poverty and resource depletion	Family planning, modern contraception, and birth control
Ester Boserup	Population pressure stimulates agricultural innovation (necessity is the mother of invention)	Intensification of farming methods and land use
Julian Simon	Humans are the ultimate resource; human minds and knowledge expand resource supplies	Free market mechanisms, secure property rights, and technological innovation
Karl Marx	Poverty is caused by unequal distribution and capitalist ownership, not overpopulation	Equal access to means of production and restructuring class wealth

When you use it

Use to compare theoretical perspectives on the relationship between population growth, resources, and development.

Watch out

Boserup views population growth as the driver of agricultural innovation, whereas Malthus views population growth as outstripping fixed agricultural ceilings.

Pro-natalist and Anti-natalist PoliciesReference tablePro-natalist · Anti-natalist

Policy Type	Primary Goal	Key Policy Tools	Country Examples
Pro-natalist	Increase fertility and population growth rate	Maternity pay, birth premiums, child care support, housing subsidies	France, Germany, Sweden, Italy
Anti-natalist	Lower fertility and curb population growth rate	Family planning, contraception distribution, child taxes, birth limits	China (One-Child Policy), India, Kenya

When you use it

Use when classifying government population policies, their objectives, and their implementation tools.

Watch out

Pro-natalist policies incentivize higher fertility to combat ageing and declining workforces, whereas anti-natalist policies restrict births to reduce resource pressure.

Challenges of economic development

Categories and Scales of CorruptionReference tableBribery · Theft of public assets · Patronage

Category	Core Mechanism	Grand-Scale Form
Bribery	Payments to public officials to influence decisions	Kick-backs
Theft of public assets	Embezzlement, tax evasion, or diversion of state funds	Kleptocracy
Patronage	Favoritism and nepotism in allocating public resources	Crony capitalism

When you use it

Use to classify acts of corruption into bribery, asset theft, or patronage and identify their systemic grand forms.

Watch out

Systemic grand theft of state assets by high officials is kleptocracy, whereas systematic large-stakes favoritism in public contracts is crony capitalism.

Gini and CPI Scale DirectionsCommon mistake

When you use it

Use when interpreting numerical index scores for economic inequality (Gini) and corruption levels (CPI).

Watch out

Do not invert the scale meanings. A Gini score of 0 is perfect equality and 1 (or 100%) is maximum inequality, whereas a CPI score of 0 is most corrupt and 100 is least corrupt.

Drafted from Grade 12 Geography, pages 124-152, then checked twice before it went up

Types and Thresholds of PovertyReference tableAbsolute poverty · Relative poverty · Persistent poverty

Type	Income Level	Core Characteristic
Absolute poverty	Below subsistence threshold	Cannot meet basic survival needs, unaffected by GDP growth
Relative poverty	< 50% of average income	Meets basic needs but lacks standard societal comforts
Persistent poverty	50% to 60% below average	Low income lasting for 2 out of 3 consecutive years

When you use it

Use to distinguish between absolute, relative, and persistent poverty using income boundaries and living standard criteria.

Watch out

Relative poverty shifts with a country's economic growth, while absolute poverty remains below the basic survival line regardless of national GDP growth.

Solutions to environmental and sustainability problems

Primary versus Secondary Air PollutantsReference tablePrimary Pollutants · Secondary Pollutants

Category	Mechanism of Origin	Major Textbook Examples
Primary Pollutants	Emitted directly from specific identifiable sources	$\text{SO}_2$ , $\text{NO}_2$ , $\text{CO}$ , VOCs, primary particulates
Secondary Pollutants	Formed in the lower atmosphere via chemical reactions driven by sunlight	Ground level ozone ( $\text{O}_3$ ), photochemical smog

When you use it

Use when distinguishing atmospheric pollutants by their origin and formation mechanisms.

Watch out

Do not classify ground level ozone as a primary emission. It is a secondary pollutant synthesized in the troposphere from NOx and VOCs under solar radiation.

Contemporary global geographic issues and public concerns

Forms of Food InsecurityReference tableChronic · Transitory

Insecurity Form	Duration	Primary Cause
Chronic	Continuous	Persistent inability of a household to purchase or produce enough food.
Transitory	Temporary	Short-term decline in food access from price spikes or production shocks.

When you use it

Use when classifying food security challenges and identifying the root mechanism of famine.

Watch out

Famine is the worst form of transitory food insecurity, rather than a permanent state of chronic food insecurity.

Types of DroughtReference tableMeteorological · Hydrological · Agricultural

Drought Type	Primary Focus	Key Characteristic
Meteorological	Precipitation deficit	Rainfall falls significantly below the long-term average for a region.
Hydrological	Water resource deficit	Stream flows, lake levels, and groundwater fall below normal requirements.
Agricultural	Soil moisture deficit	Water shortage directly impedes crop growth and disrupts the rural economy.

When you use it

Use when distinguishing between meteorological, hydrological, and agricultural droughts.

Watch out

Do not treat these three terms as interchangeable synonyms. Hydrological drought can occur in an irrigated basin downstream due to rainfall deficits upstream, even if local rainfall is normal.

Geographical enquiry and map making

Data Classification Methods in Choropleth MapsReference tableNatural Breaks (Jenks) · Equal Interval · Quantile · +1

Method	Grouping Logic	Key Characteristic
Natural Breaks (Jenks)	Maximizes within class similarity and between class differences	Default option in most GIS software
Equal Interval	Divides data range into equal size sub ranges	Simple to understand but distorts highly skewed data
Quantile	Places an equal number of observations in each class	Useful for percentile and ranking comparisons
Standard Deviation	Divides classes based on distance from the statistical mean	Shows how much values deviate from the average

When you use it

Use this when selecting or interpreting statistical grouping methods for choropleth mapping in GIS.

Watch out

Equal interval classification distorts data visualization when values are heavily skewed across geographic units.

GIS Spatial Analysis MethodsReference tableAttribute Query · Spatial Query · Proximity (Buffering) · +1

Operation	Data Input	Main Function
Attribute Query	Non spatial tabular database	Selects features based on logical table conditions
Spatial Query	Positional and coordinate data	Selects features based on geographic location and distance
Proximity (Buffering)	Vector points, lines, or polygons	Generates boundary zones of influence around features
Overlay Analysis	Multiple overlapping thematic layers	Combines geometry and attributes to create new layers

When you use it

Use this when distinguishing between non generative querying and new data generating spatial operations in GIS.

Watch out

Attribute queries only evaluate table records without geographic positions, while spatial queries require geographic coordinates.

Levels of Measurement in Geographic DataReference tableNominal · Ordinal · Interval · +1

Scale	Ordered	Meaningful Distance	Absolute Zero	Example
Nominal	No	No	No	Jersey numbers, land use type
Ordinal	Yes	No	No	Educational attainment ranking
Interval	Yes	Yes	No	Temperature in Fahrenheit
Ratio	Yes	Yes	Yes	Weight, population count

When you use it

Use this when identifying the appropriate mathematical measurement scale for geographic attributes.

Watch out

Interval scales allow meaningful differences and averages, but do not have an absolute zero so ratios cannot be calculated.
