Metamorphic rock can result from the exposure of existing igneous, metamorphic, and sedimentary rock to high temperatures, high pressure, or a combination of both.
The essential force in the metamorphic rock formation is pressure. The needed changes are driven by changes in the physical measures of temperature and pressure. As these conditions change, alterations in the composition of the minerals and textures follow.
Depending on the pressure and temperature conditions under which a rock undergoes metamorphism, differing groups of minerals tend to form. These differing groups formed under differing conditions are known as metamorphic facies. For more information, please see the related link.
By a process of melting and re-solidification of the melt produced..
Gneiss is a Plutonic metamorphic rock which is formed under high pressure and temperature condition at Katazone or Lower Zone.
Sedimentary rocks change under great pressure and temperature condition to form metamorphic rocks
the recrystallization of unmelted material under high pressure results in Metamorphic Rock

No metamorphic rocks are formed deep in the crust under great temperature and pressure. No air is down there.

there should be cause you dont know what might happend if there are no curfews for those under 18!(: bye
Under influence of pressure and temperature, a rock can change, the process is called deformation or metamorphism, the result is a metamorphic rock. This can happen to igneous rocks as well.
These will be metamorphic rocks:Regional metamorphosis occurs under heat and pressureThermal/contact metamorphosis occurs under heat only

Yes, metamorphism occurs under influence of pressure and temperature, igneous rocks aren't except from that.
