Question

Quizplus · Accepted Answer

Lifting and casting are indeed two procedures used to preserve impressions (such as footprints, tire tracks, etc.) that cannot be directly submitted to the laboratory for analysis. Lifting involves transferring the impression to a medium that can be transported, while casting involves filling the impression with a substance that hardens to create a three-dimensional replica of the impression.
