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.
Chemical weathering is the breakdown of rocks as a result of a change in their mineral composition. In this type of weathering, minerals can either be added to or removed from rocks. Water and acids are the major destructive agents of chemical weathering because they can dissolve minerals that hold rocks together by chemically changing the rock and causing it to crumble.
