Heat and pressure cause granite to become gneiss and change sandstone into quartzite.
What causes granite to be transformed into gneiss.
What causes granite to be transformed into gneiss how is sandstone transformed into quartzite.
Plate tectonics typically subduction force basaltic magmas to rise beneath the continents.
As the basalt releases heat and fluids large chunks of continental curst have the potential to transform into granite.
When subjected to intense heat and pressure granite will.
Heat and pressure cause granite to become gneiss and change.
The appearance of granular minerals is what marks the transition into gneiss.
Add heat to this process and magmas release co2 and water that help melt rocks.
Melting you answered correctly.
Another important structural change is the development of foliation or linear appearance in a gneiss.
Short succinct and correct answer.
These rocks primarily consist of quartz feldspar and mica.
It takes thousands of years for granite to cool.
Heat and pressure d.
Metamorphic rocks form from heat and pressure which changes the original or parent rock into a completely new rock.
Granite gneiss can also form through the metamorphism of sedimentary.
The change from granite to gneiss is not mineralogical i e.
Gneiss is a metamorphic rock granite is an igneous rock and sandstone is a sedimentary rock.
What causes granite to be transformed into gneiss.
More fleshed out fuller and still correct answer.
Compacting and cementing b.
Gneiss displays distinct foliation representing alternating layers composed of different minerals however unlike slate and schist gneiss does not preferentially break along planes of foliation.
This is due to the long minerals in the original granite lining up perpendicular to a regional stress field.
Sedimentary you answered correctly.
It is impossible for granite to turn into gneiss it is a scientific impossibility that cannot be done with only heat and pressure.
Gneiss gneiss is a high grade metamorphic rock meaning that it has been subjected to higher temperatures and pressures than schist it is formed by the metamorphosis of granite or sedimentary rock.
What geologic process can change granite igneous rock into gneiss metamorphic rock.
Intense heat and pressure can also metamorphose granite into a banded rock known as granite gneiss this transformation is usually more of a structural change than a mineralogical transformation.
Which of the following is not one of the three major classes of rock.
