The kind of images made by chipping or rubbing away the surface of a rock are called petroglyphs.
Here's a brief explanation of the other options for clarity:
- Paintings refer to images created using pigments applied to a surface, like cave paintings.
- Pictographs are images that are created by painting on a surface, not by chipping.
- Prints typically refer to images made by transferring ink or another medium to create a reproduction.
So, the correct answer is petroglyphs.
