They mostly produce explosive eruptions and are most commonly associated with convergent plate boundaries. They are also known as composite volcanoes. Stratovolcanoes are steep-sloped and cone-shaped. Stratovolcanoes are the most common and perhaps most recognisable type of volcano. ![]() Volcanoes come in a variety of shapes and sizes, primarily caused by the different types of magma, but also by how volcanoes behave and where they're located. Volcanoes are typically high ground or mountains, sometimes with very steep sides made from the magma that erupted.
