How Composite Volcanoes Are Formed

Composite cone volcanoes are also called stratovolcanoes. They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form. Over time these layers build up.

How composite and shield volcanoes are formed?

Composite volcanoes are tall, steep cones that produce explosive eruptions. Shield volcanoes form very large, gently sloped mounds from effusive eruptions. Cinder cones are the smallest volcanoes and result from accumulation of many small fragments of ejected material.

What boundary creates composite volcanoes?

Composite volcanoes, also known as stratovolcanoes, are found on convergent plate boundaries , where the oceanic crust subducts beneath the continental crust.
