gneiss
Metamorphisism (heat and pressure)
gneiss
Marble.
Usually it is metamorphic rocks that are formed by heat and pressure, but sedimentary rocks can too. Usually, the word 'sedimentary' means 'of sediments' which means that it is composed of lots of layers upon layers compacting down. In that case, pressure is essential, but heat isn't always needed.
It would undergo metamorphism, if the heat and pressure are sufficient.
gneiss
With With enough heat and pressure, granite will become gneiss so long as it is not hot enough to melt the granite.
Granite will become gneiss.
Gneiss, if the heat and pressure are sufficient.
Granite will become gneiss.
If enough heat and pressure is applied (40000 to 60000 times atmospheric pressure and 900 to 1300 degrees Celsius), granite or any other allotrope of carbon can be turned into diamond.
It would become metamorphic rock.
Granite must be exposed to tremendous heat and pressures in order to transform into the metamorphic rock gneiss.
by adding heat and pressure
When granite is subjected to enough heat and pressure, it becomes a metamorphic rock called gneiss.
