Question

3 the map below shows the locations of four active volcanoes in the caribbean sea.
volcanoes in the caribbean
what do these volcanoes indicate about plate tectonics in the region?
a the volcanoes form an island arc, indicating a converging plate boundary.
b the volcanoes form a line, indicating a diverging plate boundary.
c two plates are moving past each other, causing faulting and magma formation.
d two plates are moving apart, creating new seafloor.

Explanation:

The Caribbean volcanoes form a curved island arc. Island arcs are characteristic of converging plate boundaries, where an oceanic plate subducts under another plate, melting to form magma that rises to create volcanoes. Divergent boundaries create mid-ocean ridges (new seafloor), and transform boundaries involve plates sliding past each other (no island arc formation).

Answer:

A. The volcanoes form an island arc, indicating a converging plate boundary.
