What best describes the geologic process of subduction?

Question

when diverging plates pull apart from undersea ridges

when a heavier transforming plate moves over the top of lighter plate

when a convergent plate meets and the heavier plate moves under the lighter plate

when convergent plates collide and form mountain ranges

Answer 1

The best description of the geologic process of subduction is:

when a convergent plate meets and the heavier plate moves under the lighter plate.

This process occurs at convergent boundaries where an oceanic plate, which is denser than a continental plate, sinks beneath the continental plate, leading to various geological phenomena, including earthquakes and volcanic activity.
