A convergent boundary causes extremely powerful earthquakes and eruptions.


A convergent boundary is where one of the plates, usually a oceanic plate, is subducted beneath a continental plate.
This plate boundary is seen on the West coast of South America causing the Andes.

Often, seawater and minerals get caught up in the subduction zone, which can cause a build up of pressure and leads to the explosive, dangerous earthquakes and volcanic eruptions you get at a convergent plate boundary.

Volcanoes that form here are called cone volcanoes and have very explosive eruptions and can cause a lot of of damage to their surroundings, however they have long periods between eruptions.

A convergent boundary can cause the formation of massive mountains.


Where a continental plate collides with another continental plate both plates buckle forming mountains. Where the Indian subcontinent collided with the Asian plate the largest mountains in the world were formed.

The Ural mountains in Asia are thought to have been caused by an older collision between continental plates.
