Summary

• Description:

  The PDF document comprises Grade 10 Geography Strand 2 Natural Systems and Processes Notes. The MS Word version is also available upon your request.

  • STRAND 2.0: NATURAL SYSTEMS AND PROCESSES
    • Sub-Strand 2.1: Rocks
      • Definition of a rock and mineral
      • Classification of rocks by mode of formation:
        • Igneous Rocks (Formation, characteristics, types: Intrusive, Extrusive, Hypabyssal)
        • Sedimentary Rocks (Formation, characteristics, types: Mechanically, Organically, Chemically formed)
        • Metamorphic Rocks (Formation, characteristics, types of metamorphism: Thermal, Dynamic)
      • Classification of rocks by age (Pre-Cambrian, Recent)
      • Distribution of rocks in Kenya (Coastal, Rift Valley, Western/Nyanza, Eastern/North Eastern regions)
      • Significance of rocks in Kenya (Building, Energy, Soil formation, Water reservoirs, Tourism, Industry)
    • Sub-Strand 2.2: Folding
      • Definition of folding and compressional forces
      • Parts of a fold (Anticline, Syncline, Limb, Axis)
      • Types of folds (Symmetrical, Asymmetrical, Overfold, Isoclinal, Recumbent, Nappe)
      • Resultant features of folding (Fold Mountains, Escarpments, Intermontane Basins, Intermontane Plateaus, Rolling Plains)
      • Distribution of fold mountains (Young and Old Fold Mountains)
      • Significance of folding (Rainfall, Minerals, Tourism, Transport barriers, Water sources)
    • Sub-Strand 2.3: Vulcanicity
      • Definition and causes of vulcanicity (Magma, Lava)
      • Classification of features:
        • Intrusive Volcanic Features (Dyke, Sill, Laccolith, Batholith, Lopolith, Phacolith)
        • Extrusive Volcanic Features (Shield Volcano, Composite Volcano, Ash and Cinder Cone, Plug Dome, Caldera, Lava Plateau, Geysers, Hot Springs)
      • Global distribution of vulcanicity (Pacific Ring of Fire, Mid-Atlantic Ridge, Great Rift Valley)
      • Significance of vulcanicity (Positive effects: Fertile soils, Geothermal energy, Minerals, Tourism; Negative effects: Destruction, Loss of life, Pollution, Rain shadow)
    • Sub-Strand 2.4: Earthquakes
      • Definition and causes (Tectonic movement, Vulcanicity, Anthropogenic)
      • Key terms: Focus (Hypocenter), Epicenter
      • Measurement of earthquakes (Seismograph, Richter Scale, Mercalli Scale)
      • Distribution of earthquake zones (Circum-Pacific Belt, Mediterranean-Himalayan Belt, Mid-Ocean Ridges, Rift Valley System)
      • Effects of earthquakes (Destructive: Loss of life, Landslides, Tsunamis, Fire, Infrastructure damage; Constructive: Spring formation, Mineral exposure, Landform formation)
      • Disaster preparedness and management (Building codes, Early warning systems, Zoning, Public education, Emergency services)
