Question

Is wind the only gradational agent in the desert?

Answer 1

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