D)hotspots

Question

Quizplus · Accepted Answer

Moderate- and deep-focus earthquakes occur along convergent-plate boundaries, where two tectonic plates are colliding and one is being forced underneath the other (subduction). This process can cause earthquakes at varying depths below the Earth's surface. Divergent-plate boundaries involve the separation of two tectonic plates, and while earthquakes may occur here, they are generally of a lower magnitude and occur at shallower depths. Transform-plate boundaries involve the sliding of two tectonic plates past each other, resulting in frequent but relatively small earthquakes. Hotspots are areas where magma rises to the Earth's surface, forming volcanic activity, but they are not typically associated with earthquakes.
