Question

why do oceanic hotspots, like the hawaiian hotspot, result in the formation of volcano chains?
a volcano chains form due to the movement of a mantle plume underneath the earths crust.
b volcano chains form along subduction zones where there are multiple mantle plumes.
c volcano chains form due to movement of tectonic plates over a stationary mantle plume.
d volcano chains form when multiple volcanic eruptions happen simultaneously.

Explanation:

Oceanic hotspots are stationary mantle plumes that melt overlying crust to form volcanoes. As the tectonic plate moves over the fixed plume, new volcanoes form sequentially, creating a chain. Option a describes subduction zone volcanoes, option b refers to multiple plumes (not the single hotspot mechanism), and option d is incorrect as eruptions are sequential, not simultaneous.

Answer:

c. Volcano chains form due to movement of tectonic plates over a stationary mantle plume.
