If two oceanic plates move towards each other at a convergent boundary, then may occur. earthquakes
faults
ocean formation
mountains
volcanoes
island chains
seafloor spreading

pick two events

I think the answer is Volcanoes.

Explanation:

If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.

When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.

Hope this helps and if you could mark this as brainliest. Thanks!

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
