How does an island arc form?
two oceanic plates collide
a mid-ocean ridge enlarges
a hot spot develops in the middle of an oceanic plate
an oceanic plate and a continental plate converge
What answer do you think it is? I will check it for you or give you info.
Honestly, I don't know I really need help
Ok ill provide some info. Hot melted substance from the slab rises and leaks in the crust, which forms a series of volcanoes. The volcanoes could make a chain of islands which is called an island arc.
or see :

So basically answer is A. I gave a breif summary to the begining of the process.
tysm I don't understand science at all
anyone got answers to the whole quick check

An island arc forms when two oceanic plates collide or when an oceanic plate and a continental plate converge. Let's break down each scenario:
1. Two oceanic plates collide: When two oceanic plates converge, one of them is usually forced underneath the other in a process called subduction. As the subducting plate sinks into the mantle, it starts to melt due to the increase in temperature and pressure. This molten rock, called magma, rises to the surface and forms a series of volcanic islands in an arc shape. This volcanic activity is usually accompanied by earthquakes and explosive eruptions.
2. An oceanic plate and a continental plate converge: In this case, the denser oceanic plate is forced underneath the less dense continental plate. The subduction of the oceanic plate creates a deep ocean trench near the point of collision. The subducted plate starts to melt, forming magma that rises to the surface and results in the formation of a volcanic arc on the edge of the continent. Over time, as more magma is added to the volcanic arc, islands can form.
On the other hand, the enlargement of a mid-ocean ridge or the development of a hot spot in the middle of an oceanic plate does not directly lead to the formation of an island arc.
A mid-ocean ridge is a divergent boundary where two oceanic plates move apart, creating new crust as magma rises to fill the gap. This process results in the formation of undersea mountain ranges, not island arcs.
A hot spot is an area of intense volcanic activity usually found in the middle of a tectonic plate, away from plate boundaries. Hot spots create a chain of volcanic islands as the plate moves over the stationary hot spot, but this does not result in the formation of typical island arcs. Instead, it creates a linear chain of islands, like the Hawaiian Islands.
So, the correct answer to your question is when two oceanic plates collide or when an oceanic plate and a continental plate converge.
