B. Oceanic-Continental Here, oceanic plates will be subducted producing volcanos to form on the continent. In this type of convergent boundaries neither material will be subducted. Instead, the plates will fold and thrust, producing landforms such as mountains. Divergent Plates Divergent plates are plates that move away from each other. What happens here is that as the plates spread apart, the pressure in the mantle is reduced creating what is called pressure release melting.
Divergent plates are also the cause of contintal rifts.
This is when pre-existing continents spead the continent apart when two divergent plates move. An example of this would be South Africa. Transform Plates Transform plates are boundaries that slide horizontally pass eachother in opposite directions producing ocean ridges. An example would be New Zealand.
