Question

kilauea is the most active shield volcano in the world. the volcano has erupted nonstop since 1983 and it is part of the hawaiian-emperor seamount chain. both the volcano and the seamount chain are the result of -

• seafloor spreading
• ring of fire
• a volcanic hot spot
• convergent boundaries

Explanation:

1. Seafloor Spreading: Occurs at mid - ocean ridges, creating new oceanic crust. It doesn't form island chains like the Hawaiian - Emperor seamount chain.
2. Ring of Fire: Is a zone of active volcanoes and earthquakes around the Pacific Ocean, related to convergent and divergent boundaries, not the formation of the Hawaiian - Emperor chain.
3. A volcanic hot spot: A hot spot is a stationary area of intense heat in the mantle. As the Pacific tectonic plate moves over the Hawaiian hot spot, volcanoes form, creating the Hawaiian - Emperor seamount chain. Kilauea is part of this chain formed by the hot spot.
4. Convergent boundaries: At convergent boundaries, one plate subducts under another, forming volcanoes like those in the Ring of Fire, not the Hawaiian - Emperor chain.

Answer:

C. A volcanic hot spot
