Explain how volcanoes in Hawaii form?

Answer 1

The Hawaiian Islands were formed due to the presence of a hotspot below the lithosphere. These are thought to be caused by up welling plumes of high temperature material (mantle plumes). These high temperature plumes cause partial melting of the crust leading to the formation of magma which rises through the lithosphere and onto Earth's surface. However, since the Earth's lithosphere is always moving while the hotspot remains stationary, the Earth's lithosphere will move the volcanoes formed by the hotspots away from it. This results in the older volcanoes becoming extinct since the source of magma is cut off, whereas new volcanoes form above the hotspot to continue and extend the chain.

Answer 2

The term Hawaiian volcanoes are what built (and continue to build) the islands in the Hawaiian-Emperor seamount chain stretching from the tropical Pacific to the coast of Russia.

They apparently form over a "hot spot" in the mantle beneath the moving Pacific plate, that is currently building the seamount called Lo'ihi, southeast of the Big Island of Hawaii. That hotspot continues to feed heated magma to Mauna Loa, Kilauea, and other active subsea volcanoes.

Islands will form when they are over that spot, then move away to the NW over a period of millions of years, often gaining coral reefs but eventually eroding as well.

Answer 3

Scientists believe that the next volcano in the Hawaiian chain should form east or south of the Island of Hawaii. To the south of Hawaii is a violent volcano rumbling quietly at a depth of 3,000 feet in the Pacific Ocean. The land that may eventually form above the sea is already called Loihi.

Answer 4

Volcanoes in Hawaii form due to the movement of the Pacific tectonic plate over a hot spot in the Earth's mantle. As the plate moves, magma rises through weak points in the plate, creating a volcano. The continuous eruption and accumulation of lava over time lead to the growth of the volcano.

Answer 5

tectonic plates move together or magma comes up the the grounds and hardends or something liike that

Answer 6

They form in large bodies of magma, called hotspots which are forced upward through Earth's mantle and crust.

Answer 7

tectonic pates. the earth is covered in self of rock(like the skin of an apple) and when they move they can spread apart or crash into each other causing mountains, volcanoes, etc...

Answer 8

they are formed from a hotspot underground
