plaqueas

Plaques are a common feature of many natural and built environments, referring to a flat, often raised or recessed, surface or layer. In geology, plaques can describe thin, tabular masses of rock or mineral that have been deposited or formed. This might include sedimentary layers or mineral veins. In urban settings, plaques are frequently found on buildings, monuments, or public spaces, serving as historical markers, dedications, or informational signs. These are typically made of metal, stone, or ceramic. The term can also be used more broadly to describe any flat, thin covering, such as plaque buildup on teeth in a dental context, or a film of material that forms on a surface. The specific meaning of plaque is thus highly dependent on the context in which it is used.
