Question

Quizplus · Accepted Answer

A large, steep-sided volcano that grows through progressive eruptions that are usually explosive and consists of layers of volcanic debris is a composite cone. This is because composite cones are formed by repeated eruptions of lava, ash, and other materials, which create layers of volcanic debris that build up over time, making the volcano steep-sided. The eruptions of a composite cone are usually explosive because of the high viscosity of the lava.
