A hot spot, unlike other forms of volcanism that rely on plate subduction, is due to rising heat from a specific location in the mantle which is very localized, not broadly regionalized. The Hawaiian Islands are a great example of the resultant landforms created by a hot spot that exists under oceanic crust. While the crust moves over the hot spot due to plate tectonics, volcanic mountains build up on the ocean floor, eventually breaching the surface of the water. As the crust moves away, the existing volcanic mountains become inactive and are replaced with newer volcanic mountains, the older ones slowly eroding below the surface of the ocean.

∙ 8y agoIf I use the example of Hawaii, a chain of islands all produced by volcanic activity from a hotpot.
Hot spots form as a magma plume erupts through the surface and produces a fissure vent on the ocean floor. The basaltic magma from this vent frequently erupts and over time builds up to form an island, built around one or more volcanoes.
As the tectonic plates gradually move the island that has built up is pushed away from the hotpot, while the hotspot remains in the same place as it is charged from within the mantle.
So it is the movement of the Earths crust due to the movement of the tectonic plates that creates chain island/ volcanoes as lava continues to erupt from the vent creating more and more islands. This island/ volcano building process is still continuing today as the Mauna Loa volcano on Hawaii is still erupting today and continues to form the landscape.

In plate tectonic theory what does a hot spot create?
A hot spot will often generate volcanoes. Many hot spots show a chain of extinct volcanoes in one direction, indicating that the plate moved over the stationary hot spot.
What type of mountain is not formed do to plate collision?
hot spot volcanoes such as the Hawaiian island chain.
What is the place where volcanoes form in the middle of plates called?
its called a hot spot, its Region of the Earth's upper mantle that upwells to melt through the crust to form a volcanic feature. Most volcanoes that cannot be ascribed either to a subduction zone or to seafloor spreading at midocean ridges are attributed to hot spots. The 5% of known world volcanoes not closely related to such plate margins are regarded as hot-spot volcanoes. Hawaiian volcanoes are the best examples of this type, occurring near the centre of the northern portion of the Pacific Plate. A chain of extinct volcanoes or volcanic islands (and seamounts), such as the Hawaiian chain, can form over millions of years where a lithospheric plate moves over a hot spot. The active volcanoes all lie at one end of the chain or ridge, and the ages of the islands or the ridge increase with their distance from those sites of volcanic activity.
Is Hawaii considered a hot spot for volcanic activity because it does not lie on the plate boundaries?
Yes. --Hawaii moves with the Pacific Plate, and (after thousands of years) the volcanoes move away from the hot spot. As a result, there is a long chain of extinct volcanoes behind the Big Island
Is Emperor Seamount Chain divergent?
No, the Emperor Seamount Chain is not divergent. It is actually a series of volcanic seamounts and underwater mountains that were formed by a hot spot, which is an upwelling of molten rock from deep within the Earth's mantle.
How have volcanoes helped to create the Hawaiian islands?
Volcanoes shot out magma which cooled down to make the Hawaiian Islands.

How is Hawaii a volcano?
AnswerHawaii is a volcanic chain of islands formed over a 'hot spot' in the Earth's mantle. As the Pacific tectonic plate slowly moves over the hot spot, volcanoes rise from the seafloor, forming the islands. A new, future Hawaiian island is rising from the seafloor at this time. As the islands move away from the hot spot, the volcanoes become dormant, resulting in a chain of eroding mountains.
How do volcanoes form there?
its a hot spot
Do you find volcanoes at a hot spot?
Yes, it is not uncommon to find volcanoes at hot spots.

What do you call volcanoes that aren't on plate boundary edges?
Such volcanoes are hot spot volcanoes.
Why are there more volcanoes in Hawaii then Colorado?
Hawaii sits atop a hot spot on the earth. The earth's crust moves slowly northward over the hot spot. That is why the islands are in line. The islands slowly shift north, and all the volcanoes on the northern islands are dormant. New volcanoes always form at the southern tip of the island chain.
