Question

What is desert pavement and how is it produced?

Answer 1

Hint: Desert pavements are usually found on alluvial fans and piedmonts below mountains in the Mojave and Sonoran Deserts. They are known as gibbers in Australia and reg in western Sahara.

Complete answer: -The percolation of limited moisture inclines to result in sideways and downslope activity of silt components beneath the ground. This directs to the concentration of gravel. Therefore, a cycle is enhanced by the continual disposal of fine sediment at the ground by wind action.
- Gravel concentrations in desert regions are occasionally referred to as lag gravels, in citation to the sediments left by the disposal of fine material. Thus, pavements are generated by the collective consequences of water and wind.
-When sand dunes in deserts are weathered and eroded by wind and water, the sand is eliminated from these areas and gets deposited somewhere else. This process leaves behind empty rock uncovered in the desert. These rock platforms are implied to be desert pavements.

Note: -Desert pavement is a surface of angular, connecting components of gravel, rock, or stones in barren regions. They are formed on level or gently bend into desert flats, fans, or bajadas and lake and river terraces.
- Two types of desert pavement are found in the northern part of the United Arab Emirates (UAE).
 The desert pavements which are formed due to wind deflation are found in depressions between sand dunes. Those desert pavements which are former due to mechanical weathering and soil formation are found on terraces and alluvial fans.
