Desert roadway shoulder surfaces typically consist of sand.

The answer to this question is soft sand.

The desert roadway shoulder surfaces are indeed typically consisting of soft sand. In the desert, there is an abundance of soil nutrients but the disadvantages of it is that desert is lack of water because it encountered insufficient rainfall.

Explanation:

Nutrients are abundant in the desert; however, the disadvantage is they lack water which is encountered due to lack of enough rainfall. Sand is usually made of small and large particles which are typically eroded, and they do not happen faster, especially in arid environments.

When a region becomes arid, no vegetation holds the soil down. This is because the sand was washed away by streams before the areas became dry because of the organic activities.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
