When magma escapes from the mantle to the sufrface of earth it causes a?
volcanic eruption
In volcanic areas groundwater heated by magma is a source of what?
In volcanic areas the heated water is a source of escape for the volcanic gases. Water heated by magma gets very hot and needs to have a place to go or the ground will explode.
Why is volcanic ash magnetic?
Volcanic ash is magnetic because the ash has iron in in the objects the lava/magma burns. Or the ash already has iron from the mantle of the Earth burning into the magma of the core.
Reservoir from which volcanic materials erupt?
Magma chamber? Or the lithosphere or a mantle plume, depending on where the volcano is.
Does the weather cause a volcano to erupt?
No because weather has no affect on the earth mantle and the mantle is the source of magma for the volcano.

How they make a volcanic?
Volcanos are formed by tectonic plates pulling apart exposing the magma in the earth's mantle.
In volcanic areas groundwater heated by magma is source of?
geothermal energy
Do scientists use volcanoes to predict earthquakes?
Yes, scientists use volcanoes to predict earthquake activity, because volcanic and earthquake activity go together. Volcanic eruptions spew out lava whose source is in the magma of the mantle. Earthquakes are caused by heat from the mantle making crustal [or lithospheric or tectonic] plates move.
Does the weather cause a volcano to erupt?
No because weather has no affect on the earth mantle and the mantle is the source of magma for the volcano.
Which layer of the earth does the magma form?
There is no layer of the Earth that is made of Magma (molten rock). There is a layer called the Mohorovicic Discontinuity (or Moho) which is the boundary between the Earth's lower crust and upper mantle. The asthenosphere is a mechanically weak ductily-deforming region of the upper mantle which lies below the Moho. The asthenosphere is thought to be the source of some magma but it is not a complete layer of molten rock.
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.
What is a geological hot spot?
A geological hot spot is where hot magma rises from the earth's mantle, which creates volcanic activity.
What is a surface expression of a plume of magma rising from a stationary source of heat in the mantle?
A hotspot volcano.
