Which feature can be produced at an ocean continental convergent boundary

a. shrinking ocean basin

b. graben bounded by horsts

c. continental volcanic arc

d. volcanic island arc

The correct answer is - D. volcanic island arc.

When a continental and oceanic tectonic plates collide, they create a convergent boundary, and there is a subduction zone, where the heavier oceanic plate goes beneath the lighter continental plate.

Because there's cracks between the two plates, the high pressure, temperature, and magma from the mantle, manage to penetrate the crust and get to the surface, when they start to form volcanoes.

The volcanoes usually come in the shape of a chain of volcanic islands, on open sea, but relatively close to the land, as it is the case with the Japanese Islands or the Indonesian Islands.

the correct answers are:

a - pacific plate;

it is the biggest oceanic tectonic plate. surrounded on all sides by continental tectonic plates, it is submerging and gradually becoming smaller and smaller.

b - north american plate;

huge continental plate, occupying big portion of the northern hemisphere.

c -eurasian plate;

alongside the north american plate, it is one of the two dominant continental plates in the northern hemisphere.

d - indian plate;

a small continental plate, that has been part of gondwanaland initially, but after the break up of it, moved towards northeast and pushed into the eurasian plate that was once part of laurasia.
