Which of the following types of boundaries is most likely to result in a subduction zone? a. divergent b. convergent c. transform d. all of the above

b. convergent

Explanation:

The convergent boundaries are the ones that usually result in a subduction zone, especially when it comes to a convergent boundary between an oceanic and continental tectonic plates. In this type of boundaries, the oceanic plate moves beneath the continental plate, and the reason for this is that it is lower and denser then the higher and less dense continental plate. As the oceanic plates moves beneath the continental plate it reaches the mantle layer in which it is melted. Ont his type of boundaries it is very common that there's lot of volcanic and earthquake activity, as it can be seen in the ''Ring of Fire''.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
