Grade 12 Geography Exam Summary — Climate & Geomorphology

Climatology and geomorphology condensed, plus the mapwork skills that make Paper 2 the easiest 30 marks in matric.

Geography Exam Summary

Climatology

  • Mid-latitude cyclones: development stages; weather before and after a cold front passes.
  • Subtropical anticyclones: the three high-pressure cells (South Atlantic, South Indian, Kalahari) and how they control SA's rainfall.
  • Tropical cyclones: formation conditions, structure (eye, eye wall), why SA rarely gets direct hits.
  • El Niño / La Niña: El Niño = drier, La Niña = wetter for SA.

Geomorphology

  • Drainage basins: watershed, tributary, confluence; dendritic, radial and trellis patterns.
  • Fluvial processes: erosion (hydraulic action, abrasion), transport, deposition; waterfalls, meanders, oxbow lakes — know the cross-sections.

Mapwork (Paper 2)

Practise gradient, vertical exaggeration, intervisibility, magnetic declination and cross-sections. These are 30+ easy marks — drill them until automatic.

Strategy

Paper 1 = theory; Paper 2 = mapwork & GIS. Don't study one and neglect the other.
