Question

multiple answer 1 point a forensic scientist examines tire impressions to find which two key characteristics? tire tread patterns skid marks (their length and direction) the nature of the impression track width and wheelbase

Explanation:

Tire tread patterns can be unique to a tire model or show wear - specific to a vehicle. Track width (distance between left and right tires on the same axle) and wheelbase (distance between front and rear axles) are key in identifying the type of vehicle that made the impression. Skid marks are more about braking dynamics rather than a key characteristic of the tire itself for identification. The nature of the impression is too vague compared to the other two specific and identifying characteristics.

Answer:

Tire tread patterns, Track width and wheelbase
