Question

Quizplus · Accepted Answer

A cinder cone is formed from low viscosity magma with a high gas content. The low viscosity allows the gas to escape and creates a buildup of volcanic debris that forms the cone shape. The high gas content contributes to explosive eruptions that eject the volcanic debris into the air, creating cinder or lapilli.
