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 -

○ ring of fire

○ a volcanic hot spot

○ seafloor spreading

○ convergent boundaries

Explanation:

To solve this, we analyze each option:

• Ring of Fire: It's a zone of convergent boundaries with many volcanoes, but the Hawaiian - Emperor chain isn't part of it.
• A volcanic hot spot: Hot spots are stationary areas of magma upwelling. The Pacific plate moves over the Hawaiian hot spot, creating the Hawaiian - Emperor seamount chain and volcanoes like Kilauea.
• Seafloor Spreading: This occurs at mid - ocean ridges (divergent boundaries) and creates new oceanic crust, not island/seamount chains like Hawaiian - Emperor.
• Convergent boundaries: These form volcanoes at subduction zones (like Ring of Fire), but the Hawaiian chain is not formed by subduction.

Answer:

B. A volcanic hot spot
