Foliation is a geologic term that is used to describe the appearance of metamorphic rocks.
Foliated metamorphic rocks such as gneiss display banding and regrouping of its mineral constituents as a result of enormous pressures and heat. The banding forms perpendicularly to the direction of pressure.…
Nonfoliated metamorphic rocks such as marble and quartzite derived their metamorphism more from heat than from directional pressure. Foliations form at right angles to intense directional pressures. Nonfoliated metamorphic rocks like quartzite and marble are mainly single-mineralic in composition, a…
The first rocks on this planet were those that formed from the molten material on the cooling surface. Rocks are still formed from molten material underground and from molten material that solidifies on the surface. There are other types of rocks that form as part of the rock cycle.

crushed limestone then it is pressurized so that it for like a solid rock but is not as rigid as a rock because you can write with it on a blackboard.
Slate is found in Brazil, United States, Africa, Spain, and China.
Everywhere at some depth, and on the surface where uplift and erosion have allowed them to be visible. They can also be found as pebbles or boulders in glacial drift, deposited in areas in which they do not normally appear.
Slate and marble
A metaporphic rock is formed when a rock is put under extreame heat and preasure for many (often thousands or millions) of years. This changes it into a new type of rock. This new rock is called a Metamorphic rock.
Rocks that have undergone a change in mineral structure or composition, without melting, through heat and/or pressure are metamorphic rocks. Examples are slate, anthracite, and gneiss.
How does contact (prograde) occur? the
changes in mineral assemblage and mineral composition that occur
Sedimentary, igneous and metamorphic
The chemical composition of individual schist rocks varies according to their mineralogy. For instance, there are talc schists, chlorite schists, mica schists and so on.

They are both rocks. Sedimentary can contain metamorphic rocks. and vice versa.
Quartzite is a metamorphic rock, the product of the metamorphism and recrystallization of sandstone due to heat and pressure.
Quartzite is a metamorphic rock. It is formed when the mineral
quartz is subjected to extreme heat and pressure of the Earth's
Slate is the metamorphic rock formed from shale. A pile of mud can turn into shale (a fine-grained sedimentary rock) with relatively low pressure, about 3 mi (5 km) down into the earth. With more pressure and some heat, shale can transform into slate. Metamorphic rock found closer to Earth's surfac…
Quartzite is formed from a protolith of sandstone. The sandstone is exposed to a gradual increase in temperature and pressure from any of a number of sources, usually from depth of burial or plate movements. The small quartz grains in the sandstone recrystallize into larger interlocked crystals form…

Metamorphic rocks are formed from igneous, sedimentary, or other metamorphic rocks. The change is brought about by either contact with an intrusive plutonic body, or by enormous pressure and heat usually derived from lithospheric plate collisions.
Metamorphic rocks can be found on the surface in the highly eroded features of old mountains, in upwardly thrust exposures at certain beach areas, and in glacial drift they can be found as erratics, rocks that are not native to an area.
Metamorphic Rocks can be found in the Earth's crust. In fact, …
Marble is a better material to use because it is more durable than schist.
Marble is better because it is a non-foliated metamorphic rock. Although it can be attacked more readily by carbonic acid containing rainwater, it does not flake and have weaknesses that are caused by the foliation…
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.
As the degree of hydration decreases in a rock undergoing metamorphosis, certain minerals cannot exist. New minerals then form that do not require water for their formation. This environment of heat, pressure, and lack of water is necessary for the formation of certain minerals.
No. Quartzite is a metamorphic rock composed primarily of the mineral quartz.

construction and landscaping. It is used a road base and may also
be used as a decorative rocks in gardens. In the olden times, it is
used as a tool like scrapers and knives.
Metamorphic rock really is found deep underground, at
the base of mountains, in zones radiating from intrusions of magma
underground, on glaciated terrain after transportation by ice, or
on the surface of eroded mountains.

rock which is derived from an original shell type sedimentary rocks
composed of a clay of volcanic ashes. It could contain quartz,
calcite, dolomite, feldspar, pyrite, rutile, graphite, chlorite,
and other minerals.
yes , metamorphic rocks are hard
All rocks except volcanic or tectonic glasses have crystals. Therefore all metamorphic rocks have crystals, however in lower metamorphic environments these crystals may remain microscopically small.
Siltstone is formed when silt-sized sediments are turned into rock. This happens when the silt sized sediments are compacted

Foliated rocks are formed by pressure, they are buried deep. Before, minerals are scattered in the rock randomly. After it goes through presure, minerals are squeezed together and line up in rows. This happens deep underground and inside mountains. The rock has the same minerals in it before and aft…
Metamorphic rocks are classified as being foliated or being non-foliated. Foliated metamorphic rocks have visible banding or sheet-like layering. Slate, phyllite, gneiss, and schist are foliated metamorphic rocks. Non-foliated metamorphic rocks do not display banding or layering. Marble and quartzit…
Amphibolite is a metamorphic rock. It forms when basaltic rock is
heated to high temperatures under pressure. Without the added
pressure the basaltic rock that would be yielded is green schist.
On the surface or underground.
Foliated rocks have layers in them. We often refer to the layers as Banding.
Some commom metamorphic rocks are: slate, quartzite, marble, schists , and gneiss, (but pronounced "nice").
It is mostly mined on mountains because there are more quarry. When mining marble, you can not use explosives because it may damage the marble by breaking it up into to small of pieces. ~Alicia~ -6th grade from EMPN
Clastic sedimentary rock is the usual type of rock formed from the products of rock weathering.
The Metamorphic Rock must undergo a process called Weathering and Erosion. Once it has become sediments it goes under another process called Cementing and Compacting. Now it has become a sedimentary rock.Trust Point me if this helped! Thanks!
Igneous rocks are metamorphosed by heat and pressure while still in a solid state. The mineral grains of the igneous rock migrate or reorganize to form the well known banded appearances in rocks like gneiss.
