Foliation is caused by heat and pressure being applied to the parent rock. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.

What kind of rocks are rocks in which the structure texture or composition have changed?
Metamophic Rock :)
What type of rock often have foliation?
Metamorphic rocks often have foliation. Schist is a common example.
Which kind of rocks are in which the structure texture or composition have been changed?
Metamophic Rock :)
Do all metamorphic rocks have layers?
No. The layering or foliation only occurs when there is a variation in the composition of the original rock. If the rock is homogeneous, then there will be no foliation.
Do all metamorphic rocks show foliation?
No. Non-foliated metamorphic rocks include quartzite and marble.
What is a metamophic rock?
a metamorphic rock is a rock that is formed from heat and pressure it can form from a sedimentary or igneous an example of a metamorphic rock is marble metamorphic rocks can have foliation like banding or layers.
2 metamophic rocks?
Slate and schist.
What are planar rocks?
Rocks that show bedding or foliation.

Foliated rocks are distinguished by?
The main way metamorphic rocks are classified is by the presence or absence of foliation. Foliated metamorphic rocks are distinguished by the type of foliation they exhibit. Types of foliation textures, include: slaty, phyllitic, schistose, and gneissi.
What describes the thin flat layering found in most metamorphic rocks?
The thin flat layering found in most metamorphic rocks is called foliation
Foliation is caused by?
Foliation in rocks refers to the process being split into thin sheets. It is caused by intense pressure that shapes rocks to align in particular directions.
What is nonfoliated texture?
Metamorphic rocks that do not exhibit foliation.
Explain what metamophic rocks look like?
