question 3 of 30
what leads to the creation of island arcs?
a collision of two oceanic plates.
b collision of two continental plates.
c collision of a continental and an oceanic plate.
d all of the above.

Explanation:

Island arcs form when two oceanic tectonic plates collide. The denser plate subducts beneath the less dense one, melting as it sinks into the mantle. The magma rises to the seafloor, erupting to form a curved chain of volcanic islands (island arcs). Continental-continental plate collisions form mountain ranges, while continental-oceanic collisions create continental volcanic arcs, not island arcs.

Answer:

A. Collision of two oceanic plates.
