1 Igneous Rocks: form by crystallizing melted material (magma). 2  They can form either on the surface (extrusive igneous rocks), or deep in the crust (intrusive or plutonic igneous rocks). 3  Volcanoes are places where magma erupts as lava or ash.etamorphic rocks: 1  form by recrystallization of either igneous or sedimentary rocks. 2  This happens when the temperature, pressure or fluid environment change and a rock changes its form (e.g. limestone turns to marble). 3  The range of temperatures for metamophism is 150C up to the melting temperature.
