Which adjective describes something that is striped, grooved, or ridged?

The adjective that describes something that is striped, grooved, or ridged is "striated." This term is often used in various contexts, including biology and geology, to indicate the presence of lines or bands that are distinct from the surrounding material. For example, in biology, striated muscles have a banded appearance due to the organization of the muscle fibers, while geological formations might show striations from natural processes such as erosion or sediment layering. The term encapsulates the visual and physical characteristics of the surface in question, emphasizing the linear, grooved nature described.

The other options do not fit this definition. "Surreptitious" refers to something done stealthily or secretly, "stave" relates primarily to the planks that form the sides of a barrel or a wooden structure, and "teetotal" describes a person who abstains from alcoholic beverages. These meanings do not align with the concept of something being striped, grooved, or ridged, thus reinforcing why "striated" is the most appropriate choice.
