When a continental and continental plate have a convergent plate boundary what happens?
the older plate subducts under the younger one

In continental-oceanic convergent boundaries how are volcanoes created and fed?
Oceanic-continental convergent do not form volcanoes
the inner core has channels to the volcanoes
