Volcanoes are present at convergent plate boundaries because
A) the plates rub together, causing friction and heat.
B) water is carried down with the subducting plate and causes the mantle to melt.
C) heat from the inner mantle travels up along the subducting plate.
D) decompression melting due to decreased pressure at the boundary causes the mantle to melt and rise into volcano formations.

Question

Quizplus · Accepted Answer

Volcanoes are present at convergent plate boundaries because when an oceanic plate subducts under a continental plate, it carries water down with it. This water causes the mantle to melt and form magma, which rises to the surface and forms volcanoes.
