Feedback: As they drift off the hot spot, the Hawaiian chain volcanoes lose their source of melt and quit erupting. But, a new volcano grows. Indeed, the new one, Loihi Seamount, is already there and erupting underwater, building toward the surface. As they cool and sink, and are eroded, the Hawaiian volcanoes disappear below sea level. Hawaiian volcanoes are “friendly”, not having highly explosive eruptions. Yellowstone is an anomaly; the hot spot is not making a huge amount of melt, and that melt is modified in coming through the continent, so Yellowstone explodes despite being a hot spot. But most hot-spot volcanoes are not highly explosive. The “protective” layer of condominiums is developing in parts of Hawaii, but lots will happen to the volcanoes in addition—earthquakes and eruptions and drifting and more—and wait until next time when we learn about sides falling off!

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
