TSA Forensic Science Practice Test 2025 – Complete Exam Prep

In a forensic investigation, conducting a comparison of soil samples from crime scenes is crucial for establishing connections between locations or linking a suspect to a specific place. Soil can carry unique characteristics based on its composition, including mineral content, texture, organic matter, and the presence of pollutants. When soil samples from a crime scene are analyzed, forensic scientists can determine whether samples collected from a suspect's clothing, shoes, or vehicle match the soil profile of the crime scene. This comparison can potentially provide critical evidence showing that a suspect was present at a particular location.

While studying soil nutrient levels and analyzing soil composition for agriculture are important in their respective fields, these analyses are typically not relevant to forensic investigations. They don't focus on the unique forensic implications needed to establish connections in criminal cases. Similarly, although comparing soil samples from diverse locations can provide valuable data, it is less directly applicable to a specific forensic context than comparing soil from crime scenes. The targeted nature of crime scene comparisons makes option C the most relevant choice for forensic soil analysis.
