Final answer:
Soil can be used in crime investigations to both cover up and solve crimes in various ways. Criminals may use soil to bury or hide evidence, while forensic scientists can use soil characteristics to link suspects or vehicles to a crime scene.
Step-by-step explanation:
Soil can be used in crime investigations to both cover up and solve crimes in various ways. When it comes to covering up a crime, criminals may use soil to bury or hide evidence such as weapons, stolen items, or even bodies. On the other hand, soil can also provide critical evidence in solving crimes. Soil composition, texture, and other characteristics can be used by forensic scientists to link a suspect or a vehicle to a specific crime scene. By comparing soil samples from the crime scene with soil samples taken from suspects or vehicles, investigators can establish a connection and strengthen their case.
