What is gneiss streak?
Gneiss does not have a streak because it is a metamorphic rock composed of interlocking minerals with no cleavage. The streak test is typically used to determine the color of the powdered form of a mineral when rubbed against a streak plate, but this is not applicable to gneiss.
What word describes a coarse grained banded metamorphic rock?
Gneiss, pronounced 'nice', is a coarse grained banded metamorphic rock.
Does gneiss have fracture?
Yes, gneiss can exhibit fractures due to tectonic stresses or weathering processes. The type and extent of fractures in gneiss can vary depending on factors such as mineral composition, pressure, and temperature conditions during formation.
What rock does gneiss come from?
Gneiss forms from high-grade metamorphism of existing rocks such as granite or other igneous rocks, as well as sedimentary rocks like shale or sandstone. It is typically composed of minerals like quartz, feldspar, and mica that have been subjected to intense heat and pressure deep within the Earth's crust.
Does gneiss react with acid?
The metamorphic rock marble would react with hydrochloric acid.
Which rock is usually composed of several different minterals?
gneiss
What is the chemical symbol is the symbol for gneiss?
The chemical symbol for gneiss is not a standard concept, as gneiss is a type of metamorphic rock composed of minerals like quartz, feldspar, and mica. Each mineral in gneiss has its own chemical symbol (e.g. SiO2 for quartz), but gneiss as a whole does not have a specific chemical symbol.
What is gneiss and schist?
Both are foliated metamorphic rocks in which individual minerals can be seen with the naked eye. The difference is that gneiss is generally more coarsely crystalline and has color banding and schist smells bad.
What minerals make up gneiss?
Gneiss is composed mainly of minerals such as quartz, feldspar, and mica. Other common minerals found in gneiss include garnet, hornblende, and biotite. The exact mineral composition of gneiss can vary depending on the specific conditions under which it formed.

Does gneiss have fracture?
Yes, gneiss can exhibit fractures due to tectonic stresses or weathering processes. The type and extent of fractures in gneiss can vary depending on factors such as mineral composition, pressure, and temperature conditions during formation.
Does gneiss scratch glass?
Gneiss, a metamorphic rock composed of granular minerals, typically does not scratch glass. The hardness of gneiss generally ranges between 6 and 7 on the Mohs scale, while glass has a hardness of around 5.5. Therefore, while some minerals within gneiss may be hard enough to scratch glass, the rock itself usually does not have the consistent properties required to do so.
What rock does gneiss come from?

Does gneiss react with acid?
The metamorphic rock marble would react with hydrochloric acid.
Gneiss and slate are what type of rocks?
Nonfoliated metamorphic rock would be:Quartzite - composed of the mineral quartz; metamorphosed sandstoneMarble - composed of the mineral calcite; metamorphosed limestone
What group is gneiss in?
A Gneiss is a Metamorphic rock
