What is the surface feature above a mantle plume called?
The surface feature above the mantle plume is known as the "hotspot".
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.
What forms to a mantle plume?
Mantle plumes result in the formation of hot spots.
What is a volcanic area on a plate where plume of mantle material rises?
Mantle plum
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
A mantle plume extended up to the surface where There is?
Hot Spot
A very long lived magma source located deep in the mantle is called?
The term hot spot is used to describe a very long-lived magma source located deep in the mantle. J. Tuzo Wilson is credited with having originated the concept of hot spots.
Why are most Hawaiian volcanoes nonactive?
The Hawian island chain was created by a "hotspot" in the Earth's mantle. This in turn is thought to be caused by a mantle plume. This is an up welling of very hot material from deep within the mantle (possibly even the core mantle boundary). The mantle plume stays in the same place, however the lithospheric plates are moving above it. So the mantle plume causes volcanism to occur at the spot on the surface directly above it forming a volcano, however as that volcano is dragged away by the movement of the lithospheric plate it is no longer over the mantle hot spot and loses it's supply of magma and becomes extinct. Meanwhile a new volcano will form in the lithosphere that is currently over the hotspot.
When volcanic island chain are formed what moves?
The mantle plume
What type of landform is formed by a mantle plume?
Hot spot and izzi rocks
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 island has both a mantle plume and mid-ocean-ridge as its volcanic system?
Iceland.
