It is mechanical weathering. They help to break rocks physically
The term that best identifies the type of weathering represented by a salt crystal growing in a crack in a rock is mechanical weathering. This occurs when physical forces, such as the growth of salt crystals, exert pressure on rocks causing them to break apart or crack.
Mechanical weathering, also known as physical weathering, only affects the size and shape of the rock without changing its mineral composition. This can be caused by processes such as freeze-thaw cycles, root wedging, and salt crystal growth.
Physical weathering involves the breakdown of rocks into smaller pieces without changing their chemical composition. This process can occur through freeze-thaw cycles, salt crystal growth, thermal expansion and contraction, root growth, and abrasion by wind and water. Over time, physical weathering can lead to the disintegration of rocks into smaller fragments.
Mechanical weathering - Disintegration - breaks down into smaller pieces, no new substance. Frost Action, Abrasion, Gravity, Organic Activity, Wetting and Drying, and Joint Sheeting are the six major causes of mechanical weathering.
The presence of ethanol can affect crystal growth depending on its concentration. At low concentrations, ethanol can act as a solvent to help dissolve the solute and promote crystal growth. However, at higher concentrations, ethanol can inhibit crystal growth by disrupting the crystal lattice and slowing down the process.

Salt crystal growth and weathering in geology occur when saline solutions infiltrate rock pores and fractures. As the solution evaporates, salt crystals form and expand, exerting pressure on surrounding materials, which can lead to rock disintegration. This process, known as salt weathering, is particularly effective in arid environments where evaporation rates are high, resulting in the gradual breakdown of rock structures. Over time, repeated cycles of crystallization and dissolution can significantly alter landscapes and contribute to erosion.

Weathering in an arid region would likely be dominated by physical weathering processes such as thermal expansion and contraction, exfoliation, and freeze-thaw cycles. The lack of moisture reduces chemical weathering processes like hydrolysis and oxidation. Wind abrasion and salt crystal growth may also play significant roles in breaking down rock in arid regions.
