What is the natural process that causes rocks to break down? Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chem â¦ ical reactions, and gravity are some of the causes of weathering.
Elements from rocks, water, and the atmosphere combine to produce soluble minerals that crystallize in rock pores, along grain boundaries, and in fine fractures, ultimately causing disintegration. This process aids in the weathering of rocks in coastal regions where salt is provided by seaspray (fig.hemical weathering (decomposition). Processes of Chemical weathering. Chemical weathering breaks down minerals into different chemical components. Rocks, such as rock salt and limestone dissolve entirely, this is known as congruent solution.
