ZIMSEC O Level Geography Notes: Wind in Deserts
- A common misconception is that wind erosion is the most dominant form of erosion in deserts.
- That is not true as water action and other forms of denudation are just as important.
- Although wind action is not the most important agent of change in deserts, its effect are far more important here than in other areas.
- You should also note that chemical weathering also occurs in deserts.
- The importance of wind action therefore varies from desert landscape to desert landscape and cannot thus be generalised.
- Wind action in deserts are also known as aeolian processes.
- These processes include erosion, transportation and deposition.
- Deflation hollows
- Dunes ( Barchan, seif/transverse)
- Sand ripples
You will note that inselbergs/bornhardts and kopjes are formed out of combined wind and water action as well as weathering processes, in fact most of the landforms above are rarely if ever formed by wind action alone.
