Final answer:
A strike-slip fault is a type of fault that does not have a fault trace.
Step-by-step explanation:
The type of fault that does not, by definition, have a fault trace is a strike-slip fault.
In a strike-slip fault, the blocks on either side of the fault slide horizontally past each other without any significant vertical movement.
Since there is no significant vertical displacement, there is no fault trace visible at the surface.
therefore, A strike-slip fault is a type of fault that does not have a fault trace.
