Pull-apart rift zones are generally associated with a ________ plate boundary.

Answer 1

Pull-apart rift zones are generally associated with a divergent plate boundary.

Explanation:

In geology, rifts are those linear zones where lithosphere is getting pulled apart. Divergent plate boundary, also named as extensional boundary or constructive boundary is a linear characteristic that exist in between both the tectonic plates that tends to move away from each other.

Major rifts can be found alongside the central axis of mid-ocean ridges, where lithosphere and new oceanic crust is created between two tectonic plates in the path of a divergent boundary.

When the two plates pull apart, general faults or breakdowns are developed on both the sides of the rifts and the central blocks start to slide downwards thereby initiating the earthquakes.
