Why do the Hawaiian Islands form a chain of volcanoes quizlet?
-The Hawaiian Islands form a chain because each of them formed over the same volcanic hot spot. Motion of the Pacific Plate carried the islands northwest, away from the hotspot/mantle plume. When this area of the continent was located further east, it sat above the hotspot that drives Yellowstone’s volcanism today.
How was the Hawaiian Emperor island chain formed quizlet?
The Hawaiian Islands were formed by volcanic activity. The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism.
How were the Hawaiian Islands formed Are they all the same age?
Are they all the same age? The Hawaiian Islands were formed from a chain of seamounts. The progressively older seamounts stretch in an arc to the northwest. The oldest Hawaiian Island is about 4 to 6 million years old.
How do volcanic chains form?
It is understood that some volcanic chains are formed by mantle plumes, hot matter rising from the Earth’s inner core, while other oceanic volcanoes emerge from tectonic-plate activity. In this respect, both processes in the Earth’s crust and the Earth’s mantle played a part in the formation of oceanic volcanoes.
What is considered the most dangerous type of volcano?
Not surprisingly, supervolcanoes are the most dangerous type of volcano. Supervolcanoes are a fairly new idea in volcanology. The exact cause of supervolcano eruptions is still debated, however, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion.
Can you burn a diamond with a lighter?
As it turns out, diamonds are flammable, though burning one is not an easy task. To do so requires extreme heat and plenty of oxygen. You can’t inadvertently set your diamond ring on fire with a cigarette lighter. Burning a diamond requires liquid oxygen and a very hot torch.
