Granite is turned into the metamorphic rock gneiss by heat and pressure that is normally regional in nature, i.e., it will cover a broad expanse of geography due to the actions of tectonic plate movements, and in particular, plate collisions. The incredible pressures that are experienced in a granite that is being subjected to these forces will cause the minerals in the rock to align themselves perpendicularly to the direction of the force being applied, causing a narrow parallel banding in their appearance called foliation.
Granite is formed from the metamorphism of igneous rocks like basalt and gabbro. These rocks undergo high heat and pressure deep beneath the Earth's surface, causing the minerals in the rock to recrystallize and form granite.
A metamorphic rock becomes granite by hitting a magma chamber in the ground and melting (becoming molten rock) And it depends on if the volcano is intrusive or extrusive,and how fast the melted rock cools and hardens. Granite is intrusive so it cools slowly, creating large crystals.
Gneiss
Granite gneiss is a metamorphic rock formed from granite.
Gneiss, Schist, Quartzite.
Granite results from a sometimes complex process involving the melt of a variety of pre-molten rock varieties, not a specific rock.

What are the parent rocks of the metamorphic rock?
Parent rocks of metamorphic rocks can include sedimentary rocks, igneous rocks, and other metamorphic rocks. Some common parent rocks are shale, granite, and basalt. The mineral composition and texture of the parent rock influence the characteristics of the resulting metamorphic rock.
True or false granite is a metamorphic rock?
False. Granite is an igneous rock formed from the cooling and solidification of magma or lava. Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
What rocks change into metamorphic rocks?
Any type of rock can become metamorphic.
How metmorphic rock form?
Metamorphic rocks are rocks which have changed from one form to another due to intense heat or pressure. Any rock (sedimentary, metamorphic, and igneous) can be changed into a metamorphic rock.
How do you change granite from sedimentary rocks to metamorphic rocks?
Gneiss is a foilated metamorphic rock.
What are the parent rocks of the metamorphic rock?
Parent rocks of metamorphic rocks can include sedimentary rocks, igneous rocks, and other metamorphic rocks. Some common parent rocks are shale, granite, and basalt. The mineral composition and texture of the parent rock influence the characteristics of the resulting metamorphic rock.
A metamorphic rock formed form granite?
Gneiss
True or false granite is a metamorphic rock?
False. Granite is an igneous rock formed from the cooling and solidification of magma or lava. Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
Who is correct a metamorphic rock is formed from a sedimentary rock or a metamorphic rock can form from an igneous rock?
A metamorphic rock can form from either a sedimentary rock or an igneous rock. When subjected to high heat and pressure, existing rocks can recrystallize and change into new types of rocks, resulting in the formation of metamorphic rocks.
What was gneiss before it undertook heat and pressure?
Gneiss was originally formed from igneous or sedimentary rocks that underwent metamorphism due to heat and pressure. These precursor rocks could have been granite, shale, or other rocks that were transformed into gneiss through the metamorphic process.
What rocks form from existing rocks?
metamorphic rock
What are intermediate materials in a rock cycle?
Intermediate materials in the rock cycle include sedimentary rocks like sandstone and shale, which are formed through the deposition and compaction of sediments. These rocks can undergo metamorphism to form metamorphic rocks like marble and schist. Metamorphic rocks, in turn, can melt to form magma that solidifies into igneous rocks like granite and basalt.
What rock can only be formed from sedimenta rock or igneous rock?
Metamorphic rocks. With proper heat and pressure sedimentary and igneous rocks can form metamorphic rocks.
Is gneiss metamorphic?
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
What rocks can granite turn in to?
Granite can undergo weathering and erosion to form sedimentary rocks like sandstone, siltstone, or shale. It can also undergo metamorphism to form rocks like gneiss, schist, or migmatite.
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
