Geography Specimen Paper 4022/2 Study Notes

Granite Minerals: Primary components include quartz, feldspar, and mica.
Sedimentary Rock Formation: Formed through the accumulation of sediments, followed by processes of deposition, compaction, and cementation.
River Transportation: Methods include traction (rolling), saltation (bouncing), suspension (floating), and solution (dissolved load).
Exfoliation Weathering: A physical weathering process common in hot, arid regions where outer rock layers peel off due to repeated thermal expansion and contraction.
Human Use: Landforms like Chinhoyi Caves provide socio-economic benefits through tourism and cultural significance.

Weather Instrumentation: Tools used to measure variables like temperature, pressure, and wind speed; models used by local communities can be improved by using standard materials like glass or thermometers for precision.
Station Model Parameters: Used to record sky coverage (oktas), wind speed/direction (knots), temperature ( $^{\circ}C$ ), and atmospheric pressure ( $mb$ ).
Diurnal Temperature Range Calculation: Defined as the difference between the maximum and minimum temperature of a single day ( $T_{max} - T_{min}$ ).
Flash Flood Precautions: Includes building on higher ground, constructing drainage systems, and using weather early warning systems.

Definition: Areas where water covers the soil or is present near the surface, supporting aquatic and terrestrial species.
Types: Include marshes, swamps, and bogs.
Benefits: Provide grazing for livestock, water purification, and biodiversity support for rural communities in Zimbabwe.
Threats: Negatively affected by construction, agriculture, and waste disposal; sustainable solutions include strict zoning and legislative protection in cities.

Resource Classification:
- Renewable: Mopane worms (amacimbi/madora), rivers, fish.
- Non-renewable: Coal, lithium, sand.
CAMPFIRE Programme: Stands for Communal Areas Management Programme for Indigenous Resources.
- Objectives: Encourage wildlife conservation, generate income through tourism, and promote sustainable resource utilization in areas like Binga.
- Socio-economic Impact: Revenue is used to build schools, healthcare facilities, and fencing to mitigate human-wildlife conflict involving elephants in the Zambezi Valley.

Mining Factors: Influenced by mineral quality, depth of deposit, market price, and infrastructure availability.
Gold Panning: Small-scale, often informal extraction of gold from riverbeds; utilizes indigenous knowledge systems for prospecting and contributes to the Gross National Product (GNP).
Industrial Classifications:
- Primary: Farming, mining.
- Secondary: Car assembly, manufacturing.
- Tertiary: Insurance.
- Quaternary: Research and development.
Industrial Location: Determined by proximity to raw materials, markets, transport networks, and labor supply.

Settlement Dynamics: Differences between rural (primary-activity based) and urban (secondary/tertiary-activity based) settlements.
Urban Land Use: Models like the concentric land-use model apply to cities like Harare, featuring a Central Business District (CBD) and expanding residential zones.
Energy Sources:
- Biogas: Organic waste.
- Geothermal: Earth's internal heat.
- Hydroelectric: Moving water.
Solar Energy: Advantageous due to Zimbabwe's high insolation and low maintenance requirements compared to grid electricity in communal farming areas.

Road Accidents in Zimbabwe: Caused by human error, poor vehicle maintenance, and deteriorating road conditions.
Mitigation Strategies: Strict enforcement of traffic laws, driver education, and government-led victim support funds.
Infrastructure Challenges: Limited capital for pipeline expansion and the high cost of road network rehabilitation.
