Question

Which type of volcanic material will dominate the eruptions along a continental volcanic arc? Which type of volcanic material will dominate the eruptions along a continental volcanic arc? Lavas of intermediate or felsic composition Mafic lavas Phreatic magmas Only felsic lavas A mix of mafic and ultramafic lavas

Answer 1

None of the options is correct.

Step-by-step explanation:

The volcanic eruptions of a continental volcanic arch will be composed, marjoritly, by andesitic lavas and pyroclastic materials. A continental volcanic arc occurs when a volcanic arc is established on a continental margin of an active zone, which occurs as a result of the collision between two tectonic plates that form a subduction zone, that is, a zone that allows one of the plates to protrude on top of the other, pushing it down.
