What is deserts made out of?

Do deserts have sand or dirt?
Most desert soils are called Aridisols (dry soil). However, in really dry regions of the Sahara and Australian outback, the soil orders are called Entisols. Entisols are new soils, like sand dunes, which are too dry for any major soil horizon development.
Was the Sahara an ocean?
Critics noted that, while some parts of the Sahara Desert were indeed below sea level, much of the Sahara Desert was above sea level. This, they said, would produce an irregular sea of bays and coves; it would also be considerably smaller than estimates by Etchegoyen suggested.

How are deserts formed and why are deserts Hot?
As we all know, deserts are scarce in water and abundant in sand. Sand and rock heat up more quickly than water. The amount of heat that must be applied to raise the temperature of a substance by 1 degree Celsius is called specific heat capacity (shc). The specific heat capacity of water is 4.19, while the shc of sand and other rocks is 0.8.
What kind of desert is the Sahara Desert?
A desert is actually just a place that has very little precipitation. Subtropical deserts like the Sahara are what people generally imagine when they think about the desert. The Sahara has rocky plateaus as well as sand dunes.
