Indian plate (continental crust) running into Eurasian plate (continental crust)
The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is called
Oceanic crust is MORE DENSE than Continental!

Volcanoes form where a convergent boundary occurs between oceanic crust and continental crust.
South American plate (continental crust) running into Nazca plate (oceanic crust)
Andes Mts. From space plate (oceanic crust)
View looking south – ocean to continental
Volcanoes also form where a convergent boundary occurs between oceanic crust and oceanic crust.
Aleutian islands of Alaska are volcanoes formed by oceanic crust converging with oceanic crust
Following volcanic islands in the Pacific Ocean can show us where oceanic crust is being subducted by oceanic crust.
