The answer is <u>Micronesia.</u>
Volcanoes occur at underwater subduction zones. In fact, volcanoes form at most if not all types of subduction zones. Subduction zones are regions where tectonic plates collide and one plate bends and slides underneath the other plate. This bent plate reaches the mantle of the Earth, putting more pressure on the hot materials inside it.
Answer:
B. intrusion of magma into fractions
Explanation:
A pluton is a type of rock that is formed when magma cools and solidifies underground, they are an intrusive igneous rock (forced into other layers of rock), usually in cracks. The three main types of pluton are bysmalith (cylindrical), lopolith (mushroom-shaped), and laccolith (blister-shaped).
Because magma is under high pressure and takes a long time to cool, it allows time for the formation of large crystals. Therefore, plutonic rocks have coarse-grained crystals that come in many different colors and sizes. A good example is granite.
<em>Considering this information we can conclude that pluton is not manmade rock, they come in different sizes (not only large) so the correct answer is B. intrusion of magma into fractions. </em>

<span>The steeply-sloping and slower-spreading parts of the mid-ocean ridge are called Oceanic ridges. These ocean ridges are the largest features in ocean basins, they are elevated regions with a central valley on the ocean floor at the boundary between two diverging tectonic plates where new crust forms from rising magma.</span>
