<em>The convergence between a continental plate and an oceanic plate</em><em> is subduction process where the denser oceanic plate force the </em><em>thinner continental plate to sink into the mantle.</em>
<u>Answer:</u><em> Option (D)</em>
<u>Explanation:</u>
The<em> type of volcanism formed the Andean Mountains in South America</em> is due to subduction process. It is due to the converging of Nazca Plate over Antarctic Plate due to gravity and made them to sink below the <em>South American Plate. </em>
This process still continues today and due to the activity, it causes volcanic eruptions and earthquakes in that region. It was reported about <em>150 - 160 (approx.) active volcanoes in the Volcanic Belt of Andes.</em>
