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.
Answer: The breaking down of rocks without changing their chemical makeup. Explanation: There are two types of weathering: Physical Weathering (also called Mechanical Weathering) is caused by things like wind or water. These break down the rock without changing its chemical structure. With physical weathering, rocks tend to crumble as they erode. Chemical Weathering is caused by acids and dissolves rocks.
