Left image: An oceanic plate sinks below a continental plate and a mountain range is formed on the edge of the continent, as in the case of the Andes. The oceanic plate sinks and melts; magma is created which rises to form volcanoes. In the second picture: In this case, the mountain range is formed in the middle of a continent, as in the case of the Himalayas. Neither of the plates sinks below the other, the material on the edges where the plates meet is pushed upwards to form mountains.
