To determine the correct description of how and where a transform boundary operates in a tectonic setting, let's look at the characteristics of transform boundaries and the options provided.
A transform boundary is where two tectonic plates slide past one another. They do not typically form trenches, as trenches are usually associated with subduction zones (where one plate moves under another). Transform boundaries are characterized by horizontal movement and can produce significant earthquakes.
Now, let's analyze the options:
A.) a trance results from rifting in forms outside of the rift on which ever plate is higher in elevation - This statement is not accurate as transform boundaries are not primarily associated with rifting or elevation differences.
B.) a trench results from drifting, and forms outside of the wrist on which ever plate is lower in elevation - This option incorrectly associates trenches with drift and transform boundaries.
C.) a trench results from subtraction and forms on the ocean floor where two plates meet - While it mentions the ocean floor, trenches are formed at convergent boundaries, not transform boundaries.
D.) a trench results from subtraction and forms in the volcanic arc on the overriding plate - Again, this describes subduction and convergent boundaries, not transforms.
None of the provided options accurately describe transform boundaries, trenches, or how they relate to subduction or rifting.
Transform boundaries typically do not form trenches; rather, they can create faults and are associated with horizontal motion between plates. It appears that the correct characteristics are not represented in the options given. If you're looking for a transform boundary description, something like "a transform boundary results in horizontal movement between two plates sliding past each other" would be more appropriate.
