Question

How does a metamorphic rock change into another type of metamorphic rock?

Answer 1

Hint:
1) Metamorphic rocks emerge from the change of existing stone to new sorts of rock, in an interaction called transformation.
2) The first stone is exposed to temperatures more prominent than 150 to 200 °C and, regularly, raised pressing factors, causing significant physical or substance changes.

Complete answer:
Metamorphism, mineralogical and primary changes of strong rocks to physical and compound conditions varying from those under which the stones initially shaped. Changes created by surface conditions, for example, compaction are generally avoided.

The most significant specialists of transformation incorporate temperature, pressing factor, and liquids. Similarly, as huge are changes in synthetic climate that bring about two transformative cycles:
mechanical separation where a stone is distorted, particularly as a result of differential pressure.
chemical recrystallization where a mineral gathering gets out of balance because of temperature and pressing factor changes and another mineral array structure.

Metamorphic rocks are shaped by colossal warmth, incredible pressing factor, and substance responses. To transform it into another sort of transformative stone you need to warm it and cover it more profound again underneath the Earth's surface.

Note:
1) Metamorphic rocks were once volcanic or sedimentary rocks, however have been changed (transformed) because of extraordinary warmth or potentially pressure inside the Earth's outside layer. They are translucent and regularly have a "crushed" (foliated or grouped) surface.
2) The word metamorphic in a real sense signifies "changed structure". Record, a transformative stone, can shape from shale, dirt or mudstone. The Taj Mahal in India is made altogether of various sorts of marble, a transformative stone. Serpentine is a sort of transformative stone that begins as the volcanic stone peridotite.
