Due to collision and friction, mantle heats up and melts plates. This activity is accompanied by earthquakes and volcanoes. Himalayan structure was formed as a result of convergent boundaries.
Oceanic-Continental: During this activity an oceanic plate collides with less-dense continental plate. As a result of greater buoyancy of continental plate, the oceanic plate gets thrust underneath the former plate. Thus, a subduction zone is formed. Western coast of South America is an example.
