* Rocks are naturally occurring: They are formed through geological processes, not by humans shaping them.
* Varied formation: Rocks can be formed from various processes like volcanic eruptions, sedimentation, and metamorphism. Each process creates different textures and structures.
* Erosion and weathering: Over time, rocks are exposed to wind, rain, and other elements that wear them down and change their shapes.
Therefore, rocks come in all sorts of shapes and sizes, and their shape is constantly evolving.
