Question

Quizplus · Accepted Answer

Composite volcanoes, also known as stratovolcanoes, are formed by explosive eruptions that build up layers of ash, dust, and lava. These eruptions are typically associated with subduction zones where one tectonic plate is forced beneath another. As magma rises to the surface, it can become trapped and build up pressure until it explodes violently. This process of explosive eruption followed by slow lava flow and ash deposition creates the characteristic cone-shape of composite volcanoes.
