Question

what does an oceanic - oceanic convergence give rise to?
continental volcanic mountains
volcanic island arcs
valleys and ridges
folded mountains

Explanation:

When two oceanic plates converge, one is subducted beneath the other. This subduction leads to magma formation. The magma rises and erupts, creating volcanic activity. Over time, this volcanic activity builds up islands in an arc - shaped pattern, known as volcanic island arcs. Continental volcanic mountains form from oceanic - continental convergence. Valleys and ridges are not the typical result of oceanic - oceanic convergence. Folded mountains are formed mainly by compressional forces in continental - continental or other types of tectonic settings (not oceanic - oceanic).

Answer:

volcanic island arcs
