Answer:
Upon contact with the continental plate, the oceanic plate, being denser, begins to sink into the asthenosphere. This sinking of the plate is called subduction. Once in the asthenosphere, the oceanic plate melts due to high temperatures. The melts thus formed come to the surface in the form of volcanic eruptions, forming a volcanic chain of subduction.
When two plates come in contact, a collision is created, which leads to earthquakes or sediment wrinkles, followed by their elevation and mountain formation.
<em>Thus, the mountain ranges were formed: the American Cordillera and the Himalayan mountains.</em>
