PVR can be determined by the following formula:

How is metamorphic rock made
Nata [24]

Good Morning!



Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock – rocks that do melt form igneous rocks instead. ... They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.


Hope this helps!

Please mark me brainliest!

Have a great day!
