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.
The effects of weathering on rocks depends on the type of weathering that occurs. Mechanical weathering occurs when rocks undergo a physical process of change. Wind is probably the most common form of physical weathering. Wind, over time, causes rock to crumble into fine particles (sand), which likely will be recemented by other processes and made available to weather again and again. Water is also a huge contributor to mechanical weathering.
