| Cinder cones are formed during early explosive stages of an eruption. Magma, a mixture of molten rock and highly compressed gases, rises upwards from its underground sources. A the magma ascends, the extreme pressure drops and gases are released and this causes an explosion out of the central vent. Solidified rock pieces of various sizes fall around the vent, creating a mound or cone. | |
