ZIMSEC O Level Geography Notes: Hot Deserts: Inselbergs

  • These are round topped mounds of rock found in deserts as a result of persistant wind erosion over long periods of time.
  • In some deserts such as the Namib desert, wind erosion has removed all the original surface leaving isolated pieces of rock that stand up as round-topped masses.
  • Some of these inselbergs may be a result combined wind and water erosion for example remains of plateau edges may be cut back by weathering after they are exposed by sheet wash.
  • Talus (scree/loose rocks resulting from weathering and mass-wasting) accumulated at the base of the slope as shown on the right hand of the photograph)
