Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.

Is a stratovolcano a divergent volcano?

No. Stromboli is associated with a subduction zone, which is a convergent boundary.


Why do you find volcanoes at convergent and divergent boundaries but not at transform boundaries?

Convergent and divergent boundaries melt rock in the upper mantle while transform boundaries do not. Convergent boundaries that involve at least one oceanic plate form subduction zones, where an oceanic plate plunges into the mantle. Volatiles carried into the mantle lower the melting point of the rock there, allowing magma to form.At divergent boundaries the crust becomes thinner. This reduces pressure on the upper mantle, thus lowering melting points and generating magma.Transform boundaries have no such means of producing magma.


What causes magma to form at convergent boundaries?

the mid ocean ridges cause the magma to form at a convergent plate boundary.


Is forming underwater mountains and volcanoes convergent divergent or transform?

Underwater volcanoes and mountains can form at both convergent and divergent boundaries.


Is Mount Vesuvius near a hot spot divergent or convergent plate boundary?

Vesuvius is associated with a convergent boundary between the African Plate and the Eurasian Plate.

What is converging and diverging?

Divergent and convergent are both boundaries that form different kinds of landmasses.


What is the similarities between convergent divergent and transform boundaries?

they both form volcanoes and earthquakes


Are divergent plate boundaries associated with folded mountains and deep sea trenches?

No. Sea floor trenches are found at convergent boundaries. divergen boundaries form mid-ocean ridges.


Why are most volcanoes located near a fault?

Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
