At convergent boundaries, where tectonic plates collide, the primary types of magmas formed are andesitic and basaltic magmas. The subduction of an oceanic plate beneath a continental or another oceanic plate leads to the melting of both the subducted slab and the overlying mantle, resulting in magma that is often rich in silica. This process can create stratovolcanoes, which are characterized by explosive eruptions due to the high viscosity of the andesitic magma. Additionally, some basaltic magma can also form from partial melting of the mantle wedge above the subducting slab.

What plate boundary does felsic rock come from?
Felsic rocks, such as granite, primarily originate from convergent plate boundaries where continental crust collides and undergoes partial melting to form silica-rich magmas. These magmas then cool and solidify to create felsic rocks.
How are volcanoes formed by convergent plate boundaries?
Where one convergent plate is subducted under another, the sinking slab (which is full of wet sediments and organic remains) is heated and some of it melts to form magmas which migrate upwards to form volcanoes on the edge of the overlying plate.
What type of boundary form a volcanic mountain range near a coastline?
They form on convergent 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 are the tectonic settings associated with the formation of basaltic composition magmas?
Basaltic composition magmas are commonly associated with divergent plate boundaries where seafloor spreading occurs, such as mid-ocean ridges. They can also form in hot spots, such as Hawaii, where mantle plumes rise through the crust. Additionally, basaltic magmas can be generated at convergent plate boundaries where oceanic crust subducts beneath continental crust.

Why do convergent boundaries form?
i am not sure
What type of boundary form a volcanic mountain range near a coastline?
They form on convergent boundaries.
Where do convergent boundary form?
convergent boundaries form when 2 plates collide, causing moutains to form over millions of years.
What causes magma to form at convergent boundaries?
the mid ocean ridges cause the magma to form at a convergent plate boundary.
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.

Additionally, basaltic magmas can be generated at convergent plate boundaries where oceanic crust subducts beneath continental crust.
What does a convergant boundary form?
There are three types of convergent boundaries: Oceanic, continental, and continental-oceanic convergent boundaries. Continental-continental convergent boundaries form mountain ranges. Continental-oceanic boundaries result in subduction zones and the recycling of lithosphere. The continental side of the boundary may form a mountain range. Oceanic-oceanic form deep oceanic trenches and sometimes volcanoes.
Which of these hazards out of earthquakes volcanoes mountains trenches and mudslides are at convergent boundaries?
Earthquakes and volcanoes are hazards typically associated with convergent boundaries where tectonic plates collide. Mountains can also form at convergent boundaries due to the collision of plates. Trenches are associated with subduction zones at convergent boundaries where one plate is forced beneath another. Mudslides are not directly related to convergent boundaries.
Is a volcanic island transform?
No. Volcanoes do not form at transform boundaries. Volcanic islands can form at convergent boundaries and at hot spots.
