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.
Weathering is simply the physical breakup (disintegration) and chemical breakdown (decomposition) of a rock. The two processes work in concert to weaken and tear apart the rocky foundation so it can be more easily eroded.Each processes increases the effectiveness of the other.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.
