3 a) the most common theory is that desert pavement is formed by the removing sand and other fine-grained material by wind, leaving behind the larger fragments and this fragments are shuffled into place by rain, running water, wind, gravity, creep, thermal expansion and contraction, wetting and drying, frost heaving, and micro-vibrations.
some of the small particles and clay deposit underneath the pavement surface, forming a soil horizon, protected from erosion by the overlying stony layer which remains in place due to lack of precipitation and water runoff that would disrupt the layering of the stony pavement and support disruptive vegetative growth.desert pavement surfaces are often coated with desert varnish, a dark brown, sometimes shiny coating that contains clay minerals.
