What is an area of volcanic activity far from a tectonic plate boundary?
mantle plume
What is a hot plume of mantle material which may extend to the core mantle boundary produces a?
A hot plume of mantle material, which may extend to extend to the core-mantle boundary, produces a(n) a volcanic region a few hundred kilometers across
How did the Hawaiian chain island form?
The Hawaiian Island chain formed from a mantle plume and moving plates. The rising mantle plume causes crustal material to melt at depth, which results in volcanism and finally in the formation of a volcanic island. Since the Pacific Plate is in continuous (although slow) movement, the same mantle plume will cause volcanism subsequently in different places and this is expressed at the surface as a chain of volcanoes or volcanic islands.
What is mantle plume?
A mantle plume is a rising mass of extra hot mantle rock. Mantle plumes are though to be the cause of volcanic activity away from plate boundaries.
When volcanic island chain are formed what moves?
The mantle plume
Why are the Hawaiian Islands in the middle of the Pacific Plate?
The Hawaiian islands are not the result of plate techtonics, they are the result of volcanic activity relating to a particular hot spot in the Earth's mantle, from which a plume of hot magma rises upward and causes volcanic eruptions.
What island has both a mantle plume and mid-ocean-ridge as its volcanic system?
Iceland.
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.
Reservoir from which volcanic materials erupt?
Magma chamber? Or the lithosphere or a mantle plume, depending on where the volcano is.
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.

What is the difference between a hot spot and a focus?
The focus is a feature of an earthquake; it is the point underground where the earthquake originates, directly beneath the epicenter. A hot spot is an area away from a plate boundary that produces volcanic activity, most likely due to a rising plume of extra hot material in the mantle.
What type of landform is formed by a mantle plume?
Hot spot and izzi rocks
