The volcano is a powerful force in nature.

First, heat from beneath the earth’s surface melts solid rock into a white hot mixture of gas and a liquid called magma.  The gas-filled magma is lighter than the unmelted rock. This causes the magma to rise toward the surface, melting gaps in the rock as it rises. Then the magma enters the magma chamber. Since a region of magma would be hardened after a past eruption, the magma continues to push and melt its way upward. It pushes through channels of weak, fractured rock consisting of hardened magma. Eventually, the magma and gas push up to the top of the volcano and blast up through an opening called the central vent.
Volcano eruptions can be shocking and dangerous events which may cost lives or cause damage to buildings.
