metamorphic rock
the answer is and Metamorphic
Metamorphic rock
Metamorphic rock forms by the pressure on large masses of rock, causing the existing minerals in the rock to recrystallize without melting, resulting in new minerals and textures. Examples of metamorphic rocks include marble, slate, and schist.
A metamorphic rock forms by heat and pressure
Amphibolite is a metamorphic rock. It forms when basaltic rock is heated to high temperatures under pressure. Without the added pressure the basaltic rock that would be yielded is green schist.
When exposed to extreme temperatures and pressure, rocks can metamorphose into new forms such as gneiss, schist, and marble. These changes occur due to the re-crystallization of minerals within the rock under high heat and pressure conditions.
A "metamorphic" rock forms.
Under ground it's really hot, so the metamorphic forms form any rock cause of the heat and pressure
A metamorphic rock.
Metamorphic rock usually forms when a rock is altered under heat and pressure without melting. Some rocks may be metamorphosed by contact with hot water,
The parent rock for Serpentine is ultramafic rock, such as peridotite or dunite. Serpentine forms through the metamorphism of these ultramafic rocks under high pressure and temperature conditions.
