What Are The Three Kinds Of Volcanoes?
There are three types of volcanoes: cinder cones (also called spatter cones) composite volcanoes (also called stratovolcanoes) and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes which get their name from their broad rounded shape are the largest.

There are three principal ways rock behavior crosses to the right of the green solidus line to create molten magma: 1) decompression melting caused by lowering the pressure 2) flux melting caused by adding volatiles (see more below) and 3) heat-induced melting caused by increasing the temperature.

Is magma a tephra?
Closer to the surface the bubbles increase in number and size so that the gas volume may exceed the melt volume in the magma creating a magma foam. The rapidly expanding gas bubbles of the foam can lead to explosive eruptions in which the melt is fragmented into pieces of volcanic rock known as tephra.
