 The Metamorphic Rocks

 Metamorphism means to change form. 
Metamorphic rocks can form from
Igneous, sedimentary, or other metamorphic
rocks as a result of heat, pressure,
or chemically active fluids. 

This is lava called aa lava. A a lava is one of the three basic types of lava. It is a basaltic lava that has a rough or rubbly surface and is made up by broken lava blocks called clinker. -- Sophia George

When subjected to intense heat and
directional pressure, the rocks bend
into intricate folds.Metamorphism
occurs during mountain building,
magma contact, or faulting.
