What is physical erosion, and what is an example of an erosion study?
What will be an ideal response?
Physical erosion is a trace measure that examines how much something is worn down over time through human use. An example of an erosion measure is Webb's study of the rate of tile replacement around various museum exhibits. One exhibit of live chicks hatching from their shells needed to have the tiles replaced at a much more frequent rate than other areas of the museum. This would lead the researcher to believe that this is a more popular exhibit. This, when paired with other unobtrusive measures can help determine the cause of the tile erosion, whether it is sheer numbers of people crossing the area, or due to a long lingering time at the exhibit by a smaller number of people.
