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.
Sedimentary Rocks. Breaking rocks up into smaller pieces. There are lots of processes that cause rocks to break apart into smaller pieces. No matter what causes the rock to break, we call the smaller pieces sediment. A rock that forms from these smaller pieces of sediment is called a sedimentary rock!Keep in mind that even though sediments are 'smaller' pieces of rock, they might be still be the size of a house if they broke off from the side of a massive mountain. Water, wind, and gravity are the main processes that move pieces of rock from place to place. Sediment might get transported thousands of miles by one of the world's major rivers, or it might just go from the top of the hill to the bottom during a landslide or as a result of natural creep.
