Answer:
a) Geological processes contributed to the formation of vents in that region.
Explanation:
- The western parts of the United States are tectonically more active. This region has a subduction of a denser and heavy oceanic Pacific plate under the less dense and lighter American plate. And the release of the magma at the surface and the pressure is released through the hydro thermal vents.
