Answer:
The correct answer is "Earthquakes".
Explanation:
The four boundary zones that are created by tectonic plates interactions are: divergent, convergent, transform and plate boundary zones. There are different consequences of the boundary zones, including the generation of new crust, destruction of new crust, plates sliding horizontally and unclear effects, respectively. Independently of the effect of the boundary zones, the most common resulting process of these effects is the generation of earthquakes. Earthquakes are the result of the movement of tectonic plates, which takes place at all four boundary zones.
