What type of mountains form at coveragent boundaries where two oceanic plates meet?

At convergent boundaries where two oceanic plates meet, volcanic island arcs typically form. This occurs when one oceanic plate is subducted beneath another, leading to the melting of mantle material and the creation of magma. The rising magma can result in the formation of underwater volcanoes, which can emerge as islands over time. Examples include the Aleutian Islands in Alaska and the Mariana Islands in the Pacific Ocean.
