How mountain and volcano form?

Famous mountain like mount Everest in the Himalayas, is form with by continental- continental convergence.

Do you know that Japan, Phillipine and Hawaii are Volcano island?
They are form intially through oceanic-oceanic convergence. The volano started buliding up in the ocean and gradually, the drived lava emerge from the ocean and become a island.
They are also form in oceanic-continental covergence, through the subduction of the oceanic crust, follow by the rise of the magma to the continental crust and form mountain.

Japan also has the highest earthquake, poor Japan =( This is because it is situated at the center of the boundaries of different plate ( Eurasian, philipine, pacific plates), with them pushing against each other.
