How do you briefly explain how volcanoes that are located in hot spots formed?
As tectonic plate moves over a mantle plume, rising magma causes a chain of volcanic islands to form.
Explain how volcanoes that are located at hot spots form?
Volcanoes located at hot spots form by lying directly above columns of hot rock that rise through Earth's mantle. As a tectonic plate moves over a mantle plume, rising magma causes a chain of volcanic islands to form.
What is a plume and how does it cause plate movement?
In the context of plate tectonics, a plume is a column of very hot magma, much hotter than the usual temperature of the mantle, that rises through the cooler magma because the heat causes it to expand and therefore to be less dense. When the rising magma reaches the crust, it exerts force on the crust and contributes to continental drift. It can also cause volcanoes. The Hawaiian chain is an example of islands that were produced by volcanoes that were all caused by the same plume. As the crustal plate moves, the plume strikes different parts of the crust.
How does a hot spot make a chain of volcano mountains?
A hot spot deep in the Earth's mantle creates a rising plume of magma that is even hotter than the regular magma of which the mantle is composed. When this plume of magma hits the crust, it breaks through and causes a volcano. The reason why we eventually wind up with a whole chain of volcanoes, rather than just one, is continental drift. The Earth's crust is moving, while the plume of magma is always directed at the same spot, so as the tectonic plate slowly drifts by, the plume will impact different parts of that plate.
Is Yellowstone located at a divergent plate boundary?
Yellowstone is situated within a tectonic plate, not at a plate boundary! Volcanic activity is thought to be as a result of a mantle plume, much like the volcanism that created the Hawaiian Island chain.

What is an area of volcanic activity far from a tectonic plate boundary?

How was Honolulu formed?
The Hawaiian islands are the result of a hot spot beneath the Pacific Plate. Hot material rises from deep within the mantle and collects beneath the lithosphere. Some of it rises through the crust and erupts at the surface, forming volcanoes. Those volcanoes gradually build up into islands. As the plate moves over the hot spot the old volcanoes go extinct and new ones form.

Are hot spots plate boundaries?
They can occur anywhere. For example the Hawaiian islands are caused by a hot spot thought to be created by a mantle plume and they are a very large distance away from any plate boundary. However some geophysicists also believe that Iceland sits atop a hotspot that is also caused by a mantle plume that coincidentally coincides with a tectonic plate boundary (the Mid-Atlantic-Ridge).

How can one mantle plume form several volcanic islands?
Mantle plumes appear to remain nearly stationary. However, the lithospheric plate above a mantle plume continues to drift slowly. So, the volcano on the surface is eventually carried away from the mantle plume. The activity of the volcano stops because it has moved away from the hot spot that supplied it with magma. A new volcano forms, however, at the point on the plate's surface that is now over the mantle plume. Some mantle plumes are long and linear. As magma generated by these plumes rises through cracks in Earth's crust, a line of hotspot volcanoes forms. Unlike volcanoes that form individually as a plate moves over a mantle plume, hot-spot volcanoes that form in lines over a long plume do not have any particular age relationship to each another.Mantle plumes appear to remain nearly stationary.

When volcanic island chain are formed what moves?
The mantle plume
Where is a volcano most likely to form?
Volcanoes are most likely to form along tectonic plate boundaries, such as convergent and divergent plate boundaries. Convergent boundaries occur when two plates collide, causing one plate to subduct beneath the other, creating volcanic activity. Divergent boundaries occur when two plates move apart, creating gaps where magma rises to the surface and forms volcanoes. Additionally, volcanoes can also form within hotspots, where a plume of hot magma rises through the Earth's mantle.
What is a volcanic area on a plate where plume of mantle material rises?
Mantle plum
