Rock weathering is reduced in deserts because of the lack of moisture. Weathering processes such as chemical weathering rely on water to break down rocks, which is limited in desert environments. Additionally, the extreme temperature fluctuations in deserts can inhibit the expansion and contraction of rocks that would typically contribute to mechanical weathering.
Mechanical weathering, such as thermal stress from temperature changes, and chemical weathering, like reaction with water and minerals, are common causes of rock breakdown in the desert. Additionally, wind erosion can also contribute to the breakdown of rocks in arid regions.
Depending on what type of desert, the atmosphere is usually dry, and sometimes windy. In a desert such as the Sahara, the weather is hot and dusty, although cooler at night. In a desert like Antarctica, the weather is extremely cold and windy.
The formation of rock formations in the desert is primarily influenced by processes such as weathering, erosion, and sedimentation. Over time, these processes break down existing rocks, transport sediments, and deposit them in layers, eventually leading to the formation of unique desert rock formations like arches, hoodoos, and mesas.
Hydration
Water is the substance that has the greatest effect on the rate of weathering of rock. Water can seep into cracks in rock, freeze and expand, causing the rock to break apart. Water can also chemically react with minerals in the rock, leading to chemical weathering.
Water causes the greatest amount of weathering, especially flowing water. Water is scarce in deserts.

The main form of weathering in a desert is decomposition.
No, desert pavement is caused by wind which is physical weathering.

Mechanical weathering; as distinct from chemical weathering; occurs when the surface of a rock (say) is mechanically abraded. Such as the grits of a river wear away the bedrock. The aeolian sands in the desert will sculpt exposed rock ribs. A glacier will gouge the surface away by grinding the bedrock with boulders, stones, and grit entrained in the ice mass. This type of weathering produces vast quantities of rock flour. Much of the volume of a glacial valley has been turned into rock flour.

The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
Mechanical and chemical weathering both occur.
The effect of weathering is to reduce the volume of the igneous rock.
Weathering may change the rock into many shapes.
By weathering either by physical or chemical weathering.
