Identify the type of metamorphic rock that can be formed when each of the following is exposed to heat or pressure:
Limestone:
Sandstone:
Shale:
Granite:
Changes in the limestone's chemical properties due to external forces can result in the creation of marble. Sandstone turns into a hard metamorphic rock called quartzite when heated. Shale that is exposed to extreme heat and pressure can change into slate. Because of the way granite forms, it possesses a special resistance to heat.
But if you think differently then this is what happens with all of them when heat is added. ^
If this helped please give stars and a thanks ^.^ much appreciated!
