What is the surface feature above a mantle plume called?
The surface feature above the mantle plume is known as the "hotspot".
A very long lived magma source located deep in the mantle is called?
A mantle plume. These plumes are thought to be responsible for hotspot volcanism, where magma erupts through the Earth's crust in localized regions, such as the Hawaiian Islands. The source of mantle plumes is still debated among geologists.
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.

Is plume the same thing as a hotspot?
No, a plume and a hotspot are not the same thing. A plume is a column of hot rock that rises in the mantle, whereas a hotspot is a location on the Earth's surface where magma from the mantle comes up and creates a volcanic activity like a volcano. Hotspots can be associated with plumes, but they are not the same thing.
When mount st helens erupted did it form the hawiian islands?
No. The Hawaiian islands are formed by a mantle plume.

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
What type of landform is formed by a mantle plume?
Hot spot and izzi rocks

What forms to a mantle plume?
Mantle plumes result in the formation of hot spots.

When A mantle plume extends up to the surface where there is a .?
When a mantle plume reaches the surface, it can create a hotspot, leading to volcanic activity. This can result in the formation of volcanic islands, like the Hawaiian Islands. Mantle plumes are a source of heat and material that contribute to the formation of new crust and landmasses.
What is an area of volcanic activity far from a tectonic plate boundary?
mantle plume
What island has both a mantle plume and mid-ocean-ridge as its volcanic system?
Iceland.
