What are Island Arcs ?The andesite originates most likely from the melting of parts of the descending plate and sediments that had accumulated on its surface. What list identifies minerals present in andesite from the greatest percentage by volume to the least percentage by volume?

As explained below.

Explanation:

The island arcs are a long chain of active volcanoes and have intense seismic activity and are found along with the rings of fire as the convergent plate boundary and form a chain of active or the extinct volcanoes that form an arc-shaped pattern on he deep-sea trench. Andesite is an extrusive igneous rock of the intermediate composition and is an intermediate between the basalt's and the rhyolite and has 50 to 67% of the Silicon oxide and is dominated by the pyroxene s and the hornblende and feldspar is present in lower amounts. This andesite is characterized by the presence of the subduction zone s and the mental wedge.
