geniss is stronger than granate because during metamorphic the granate change into geniss

What is metamorphosed granite?
Metamorphosed granite, also known as gneiss, forms when granite undergoes high temperatures and pressures deep within the Earth, causing its minerals to reorganize into distinct layers or bands. This process results in a metamorphic rock with a banded appearance and typically a coarser texture than the original granite.
How is gneiss rock formed?
Gneiss is formed from pre-existing rocks that are subjected to intense directional pressure and heat, causing an alignment of their constituent minerals into parallel bands, a texture that is referred to as foliation.
What does gneiss form into?
There is no grade of metamorphism beyond gneiss. Higher grades of metamorphism mean higher temperature and pressure. Beyond the conditions that form gneiss, temperatures are high enough to melt rock, at which point the resulting rock will be igneous rather than metamorphic.
Which rock is the hardest granite or chalk?
Chalk is a sedimentary rock composed primarily of Calcium Carbonate. Calcium carbonate is also the number one mineral at the Marble spec. Hardness of Chalk is around 3 Mohs. Granite stay at the number 7 at the Mohs scale and Granite is harder than Marble. Granite is mostly composed by feldspat (christal).
What is the hardest rock between granite and marble?
Granite is generally considered to be harder than marble. Granite is a very hard, durable rock composed mainly of quartz, feldspar, and mica, while marble is a softer rock primarily made of calcite. This difference in composition gives granite greater resistance to scratching and other forms of wear compared to marble.
Is bauxite harder than granite?
No, granite is harder than bauxite. Granite is a type of igneous rock that is known for its durability and hardness, while bauxite is a sedimentary rock that is softer in comparison.
What rock is harder than sandstone?
Granite is typically harder than sandstone. Granite is an igneous rock that forms from the cooling of molten magma, making it more dense and resistant to abrasion compared to sandstone, which is a sedimentary rock.

The rock beneath the continents is made of?
The rock beneath the continents is primarily composed of granite and other metamorphic rocks such as gneiss and schist. These rocks are older and less dense than the oceanic crust, forming the thick, continental lithosphere that supports the continents.
Is diamond harder than gypsum?
Yes, diamond is harder than granite. Diamond is the hardest mineral known. And it is several times harder than granite.

Is granite harder than limestone?
Yes
Are diamonds harder than granite?
Yes
What is granite rock explain?
Granite is an igenous rock that was formed via solidification of a magma several kilometers deep in the crust. Granite is mineralogically defined a s a rock that has a quarz/feldspar ratio of 0.2 to 0.6, and has a ratio of alkali feldspars vs plagioclase of 1/3 to 0.9. Furthermore Quarz and feldspars must make up more than 10 % of the minerals of the rock and it may not have been deformed to become a metamorphic rock (gneiss). Chemically granite is defined as the igneous rock type richest in silicon.
