Which type of impression is left by the friction ridges of a fingertip on a surface?

The correct answer is a fingerprint. This type of impression is created when the unique patterns of friction ridges on a fingertip come into contact with a surface and leave an impression that can be positive or negative, depending on the surface and the medium being transferred. Fingerprints are characterized by their intricate and unique ridge patterns that are specific to each individual, making them a valuable tool for identification in forensic science and law enforcement.

The other types of impressions, such as footprints, handprints, and palm prints, pertain to impressions made by different parts of the foot or hand. A footprint is an impression left by the foot, while a handprint is created by the entire hand making contact with a surface. A palm print specifically captures the patterns of the palm of the hand. Each of these impressions serves a different purpose in forensics, but in relation to fingertips, the appropriate term is fingerprint.
