What else can I help you with?
Is gneiss a metamorphic sedimentary or igneous?
Gneiss is a banded metamorphic rock.
Is gneiss igneous metamorphic or sedimentary rock?
It is a Metamorphic rock
What types of rock can be changed to a metamorphic?
All rock types, igneous, sedimentary, and even metamorphic can be altered to new metamorphic rock.
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.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
Is gneiss an example of igneous rock?
No. Gneiss is a metamorphic rock.
Is Gneiss a sedimentary metamorphic or igneous rock?
Gneiss is a metamorphic rock that forms from the recrystallization of pre-existing rocks under high temperature and pressure conditions. It is characterized by its banded texture and coarser grain size compared to other types of metamorphic rocks.
How is gneiss similar to granite?
Granite is an igneous rock and gneiss is a metamorphic rock.
Which of the following is NOT an example of metamorphic rock marble gneiss slate shale?
Shale is a sedimentary rock, not a metamorphic rock.
Does igneous rock have to become sedimentary rock before it can become metamorphic rock?
No, igneous rock can undergo metamorphism without becoming sedimentary rock first. Metamorphism can occur in any rock type (igneous, sedimentary, or metamorphic) when exposed to high temperature and pressure, leading to the formation of new minerals and textures.
Can igneous rock become metamorphic rock without first becoming sedimentary rock?
Yes. A prime example is that granite can undergo metamorphism and become gneiss.
Why is gneiss hard?
Gneiss is metamorphic rock that forms from preexisting sedimentary or igneous rocks. It is developed under high temperature and pressure conditions, causing it to become hard.
