Question
Is wind the only gradational agent in the desert?
Solution
- Deserts are areas with little or no rainfall.
- Therefore we find only limited or non-existent plant (animal) life.
- Due to lack of moisture, chemical weathering is almost absent.
- Mechanical weathering is the dominant activity.
- Wind obviously becomes the only major agent of erosion, transportation and deposition.
- Wind can blow without any obstructions of trees etc.
- Wind is also supplied with fine dust which help carve the landforms.
- Flowing water is an occassional agent of erosion whenever there are heavy showers followed by flash floods.
- Such showers are very rare.
