Question

select the correct answer. the many volcanoes located along the edge of the pacific ocean make up the ring of fire. how does subduction play a role in the volcanic activity in the ring of fire? most of the plate boundaries involve one plate sliding underneath another. most of the plate boundaries involve plates spreading apart, forming new ocean floor. most of the plates are stationary, capable only of forming hot spots. most of the plates rub horizontally against each other.

Explanation:

Subduction is the process where one tectonic plate slides beneath another. In the Ring of Fire, most plate - boundaries involve this subduction process. When an oceanic plate subducts beneath a continental or another oceanic plate, it melts due to the high pressure and temperature, creating magma that rises to the surface and causes volcanic activity. The other options describe different plate - boundary processes (spreading apart is divergence, stationary plates forming hot - spots, and horizontal rubbing is transform boundaries) that are not related to subduction.

Answer:

Most of the plate boundaries involve one plate sliding underneath another.
