When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
Because their structure and mineralogy is not stable in the pressures and temperatures causing the metamorphism.

Regional metamorphism is the creation of metamorphic rock from large geographically significant processes like plate tectonics. Contact metamorphism is the creation of metamorphic rock from the proximity of an existing rock to a heat source provided by a plutonic intrusion.
contact metamorphism
First, through metamorphism, then by melting and magmatism.
Sedimentary rock is formed generally at low temperature and pressure conditions.Therefore a change in this conditions to higher levels triggers mineralogical change.The driving forces for metamorphism are changes in temperature, pressure, and composition of the environment or strong deformation.These changes cause recrystallization in the solid state as the rock changes toward equilibrium with the new environment.Hence, formation of metamorphic rocks.
Metamorphism involves temperature and high pressure and chemical changes. The high pressure, chemical changes and temperature are the metamorphism that act on a rock that makes it change.

Burial metamorphism
By undergoing changes, such as weathering and metamorphism.

The color of sedimentary rock changes during metamorphism due to minerals. New minerals introduced can change the color of the rock.

Igneous metamorphism
The two processes resulting from sedimentary into metamorphic rock are known as contact metamorphism and regional metamorphism. Regional metamorphism most notably involves two tectonic plates colliding, while contact metamorphism occurs due to the intrusion of magma.
