divergent plate boundries
What you call a pull apart rift zone is what is called a divergent boundary. Most divergent zones are located under water and are a zone where new oceanic crust is born. One location where a divergent zone can be seen on land can be found in Iceland.
A convergent plate boundary involves one lithospheric plate sliding under another, leading to subduction zones where one plate is forced beneath the other. This process is associated with the formation of deep ocean trenches and volcanic arcs.
Hekla volcano is located along a divergent plate boundary in Iceland, where the North American and Eurasian plates are moving apart. This movement creates rift zones where volcanic activity is common, including Hekla.
The geothermal gradient associated with divergent plate boundaries is typically lower than the gradient at subduction zones. This is because at divergent boundaries, the crust is thinning and heat can more easily escape from the mantle, while at subduction zones, the subducted plate can carry heat deeper into the Earth, increasing the geothermal gradient.

Subduction Zones are usually known to be part of the Destructive Plate Boundary. The changes that occur in this boundary are: Oceanic crust moves towards the continental crust, but due to the weight of the oceanic crust, the oceanic crust sinks and gets destroyed. This forms deep sea trenches and island archs with volcanoes. As the oceanic crust is forced downwards, the increase in pressure can trigger earthquakes to strike... Basically, the two plates (oceanic and continental) are associated with subduction zones.... Hope this helped ^ ^

A convergent plate boundary is caused by a downward convection current in the mantle. At these boundaries, tectonic plates move towards each other, resulting in subduction zones or collision zones, where one plate is forced beneath the other.

subbduction zones
subduction zones, ex. maranas trench
A region where a plate descends is called a subduction zone. In this type of plate boundary, one tectonic plate is forced beneath another due to differences in density. Subduction zones are commonly associated with volcanic activity and earthquakes.
usually you find most of the zones of earthquakes and volcanoes at a plate boundary.
No, subduction zones are where tectonic plates collide and one plate is forced beneath the other. New crust is formed at divergent plate boundaries, where plates move apart and magma rises to create new crust.
Earthquakes associated with convergent plate boundaries typically occur in the subduction zones where one tectonic plate is forced beneath another. These earthquakes are known as megathrust earthquakes and can have very high magnitudes due to the intense tectonic forces involved in the subduction process.
