The desert roadway shoulder surfaces are indeed typically consisting of soft sand.

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.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
