* Erosion: Wind, rain, ice, and other natural forces constantly wear away at rocks, changing their shape and size. This is called erosion.
* Weathering: Chemical reactions (like acid rain) and biological processes (like plant roots) can also break down rocks, changing their composition and appearance. This is called weathering.
* Geological Processes: Earthquakes, volcanic eruptions, and tectonic plate movement can cause rocks to crack, shift, and deform.
* Human Activities: Mining, quarrying, and construction can drastically alter the shape of rocks.
So, while a rock might appear to stay the same for a long time, over geological time scales, its shape will inevitably change due to these forces.
