Metamorphic rock results from the exposure of other rock types to heat and pressure. The heat and pressure is usually provided from depth of burial, or tectonic plate interactions, but could be provided by close proximity to a magmatic intrusion.

Metamorphic rock is formed when smaller particles and minerals pack together.
Metamorphic rocks may be formed.
Metamorphic rocks may be formed.
Metamorphic rocks are formed by rocks sedimentary or igneous that change their form under intense heat and or pressure.
igneous rocks are made of lava that cools and hardens and metamorphic rocks are madeby heat and pressure.
Metamorphic rocks are made by the action of heat and pressure on pre-existing rocks. e.g. Schist, Coesite, most micas.
rocks pile on other rocks pushing them downward, as they reach about one eighth of the way towards the mantle the pressure and heat make metamorphic rocks
A metaphorphic rock is a rock that undergoes changes to become a different type of rock. The rock changes due to extreme pressure wich makes them heat up, and change types.... i hope this helps :)
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
