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.
What else can I help you with?
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?
It is false. Granite is a igneous rock that was formed from magma cooling and hardening.
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.
Is glassy igneous rocks intrusive or extrusive?
Glassy igneous rocks are typically extrusive, meaning they form at the Earth's surface from rapidly cooling lava. Intrusive igneous rocks form underground from slowly cooling magma and generally do not have a glassy texture.
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?
It is false. Granite is a igneous rock that was formed from magma cooling and hardening.
What type(s) of rock ar most likely to be the parent rock of a metamorphic rock?
Metamorphic rocks typically originate from either igneous or sedimentary parent rocks. Igneous rocks, such as granite, can undergo metamorphism to form gneiss, while sedimentary rocks like limestone can transform into marble. Additionally, some metamorphic rocks can also originate from other metamorphic rocks through further metamorphic processes. The conditions of temperature and pressure during metamorphism play a crucial role in determining the characteristics of the resulting metamorphic rock.
What was gneiss before it undertook heat and pressure?
A mixture of sand and clay, mudstone, metamorphose (process of changing from one type of rock into a metamorphic rock) into gneiss rocks or schist rocks. The mudstones would change under heat and pressure to make the new Metamorphic rocks.
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 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 rocks can granite turn in to?
Granites can turn into metamorphic, sedimentary, or igneous rock through metamorphosis.
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 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.
