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.
People that live in a desert region can easily find rocks on the surface. These rocks lay on a surface of clay that is also a product of weathering rock. Weathering is the process of breaking down rocks and minerals into smaller pieces by water, wind, and ice. Sedimentary rocks are formed from the breaking apart of other rocks (igneous, metamorphic, or sedimentary rocks) and the cementation, compaction and recrystallization of these broken pieces of rock.
