Final answer:
Earthquakes and volcanic eruptions primarily occur along plate boundaries, such as the Ring of Fire in the Pacific Ocean.
Step-by-step explanation:
Earthquakes and volcanic eruptions occur primarily along plate boundaries, where tectonic plates interact with each other. There are three main types of plate boundaries: convergent boundaries where plates collide, divergent boundaries where plates separate, and transform boundaries where plates slide past each other. For example, the Ring of Fire is a major area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to the interactions of several tectonic plates.
