Magma is molten rock found below the earth's surface. The temperature at which
a rock melts is affected by its composition, pressure and water....

<sup>3</sup> Magma forms when rocks reach temperatures high enough to melt them. Most
rocks begin to melt at a temperature between 800 and 1200 degrees Celsius.
Magma composition is discussed below, followed by a description of the
controlling factors on explosivity -- viscosity, temperature, and the amount of
