They are classified by their composition.
Interesting question, generally they can, in "layman" terms. Metamorphic rocks are rocks that undergo intense heat and pressure through either REGIONAL or CONTACT metamorphism. Regional - high pressure low temperature - environments eg within a mountain range. Contact - as it implies ...
Metamorphic rocks are cause by a pre-existing rock, either igneous or sedimentary which under extremes of heat or pressure (or both) change their form. Eg Limestone (sedimentary) undergoes metamorphism to marble (metamorphic ). Sedimentary rocks are rocks that have been formed through...
There are many minerals in metamorphic rocks eg. Phyllites contain micas , Amphibolite contains amphiboles, quartz, and plagioclase. Other minerals include feldspars, biotite, pyroxenes and others such as calcium carbonate as in marble ..a result of the metamorphism of limestone.
You can identify metamorphic rocks by various minerals or a lack of thereof (mineralogy), also by foliation: whether they're foliated or non-foliated. If they show presence of shistosity or gneissosity (alignment of minerals ) , fissility and grunular appearance.
Metamorphic rocks must first be weathered or eroded into sediments. Those sediments can then get compacted or cementated. Compaction occurs when the sediments are deeply buried, putting them under a lot of pressure which causes the sediments to squash together. Cementation occurs when newly...
It is formed under immense heat and pressure.
Metamorphic rocks are formed by rocks sedimentary or igneous that change their form under intense heat and or pressure.
Two ways in which metamorphic rocks are 1) contact metamorphism (thermal) where magma comes in direct contact with surrounding igneous rock and changes it due to high temperatures and usually low pressure. 2) Regional metamorphism (dynamothermal) ,high pressures and low temperature eg...
When the rock is in a high temperature and pressure environment for a long time, their properties changes as much that you can't say that it's the same rock, so we call it a metamorphic rock. There are 3 ways: Hydrotermal, by contact or differential pressure metamorphosis.
Slate --metamorphosed shale or mudstone. Phyllite --metamorphosed slate. Quartzite --metamorphosed sandstone.
Many kinds of rocks both of igneous and sedimentary nature eg; Limestone (sedimentary ) to marble or granite or diorite (igneous) to gneiss.
Bloodstone is not a rock, but a gemstone variety of the mineral quartz, in cryptocrystalline form.
It commonly has some form of layering to it, what is called a "foliation". If it is distinctly foliated it is called a schist, somewhat less foliated: a gneiss. ! Naming a metamorphic rock on sight is subjective, also naming (and translations) vary (e.g. terms used in Europe are sometimes different...
Igneous rock can turn in to metamorphic rock by weathering and erosion. The Igneous rock is changed by heat and pressure and is turned in to the new rock, the new rock is the Metamorphic rock
It is false. Granite is a igneous rock that was formed from magma cooling and hardening.
Igneous rock is formed when molten rock cools. Examples are lava from volcanoes cooling but also rock that is pushed from the magma layer into cooler pockets under the surface of the Earth. They are characterised by having crystals in them. The larger the crystal the longer it took to cool down and...

yes, any rock can be turned to another rock through the rock cycle.
The mineralogy (i.e. the types of minerals present within the rock) and also the texture of the rock (i.e. the size, arrangement and orientation of mineral grains within the rock) along with it's structure (the presence of features such as foliation and cleavage).
where do metamorphic rocks form, the mantle crust or core?Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat...
Metamorphic rocks are created from intense heat and pressure being applied to an existing rock. The existing rock is called the protolith. They can also be formed from lava being poured over the top of the earth's surface, where rocks lay underneath. Metamorphic rocks make up a large part of our...
Minerals form in igneous rock as magma or lava cools. The minerals will form from the available chemicals in the magma as their crystallization temperature is reached. The sequence of mineral crystal formation from magma is described in the Bowen's Reaction Series. Metamorphic rock minerals are...
Due to the movement of the plates in Earth's crust, schist could be found anywhere.
Marble, Quartzite, Greenrock
it has a metallic luster usually silver and black:)
Pressure and heat from being buried under mountains.
Metamorphic rocks are most likely found at a site that is deep under ground. Metamorphic rocks are formed by other materials under great amounts of pressure. This pressure is caused by plate collisions in the lithosphere.
== Answer == 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...
No, Igneous rocks are formed by cooling molten rock (lava).Sedimentary rocks are accumulations of ground up (eroded) previously solid rock or rocks formed by biological processes.Metamorphic rocks are both sedimentary rocks and or igneous rocks that have been changed since they formed by heat and...
The alignment of minerals into bands (foliation) is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel...
Metamorphic rocks are rocks that can kill you depending on where they are such as the desert ,or mountains.Metamorphic rocks can also create itself and sediments and by sediments going through cementation,compaction,erosion weathering,deposition and burial it eventually becomes a sedimentary rock.
Metamorphic rock is made by heat, pressure and chemical action.
Usually a grayish color. Dark gray.
No, nitratine is a mineral, sodium nitrate. The largest deposits of nitratine are the deserts of Northern Chile, but it is also known from TX, NM, UT, CA, as well as Bolivia, Peru, North Africa, Egypt, Russia, Kazakhstan, and India. Quite uncommon and also water soluble, hence seldom seen on the...
because its just a question
== Answer == asteroid meteorites bolide
An igneous rock is a rock that is extremely heated and was formed with extreme pressure. An igneous rock is the kind of rock that comes out of a volcano; a metamorphic rock would need to be underground with extreme heat and pressure from the magma and molten rock.
Metamorphic rocks are formed from igneous, sedimentary and older metamorphic rocks that are introduced to extreme temperature and pressure. Because of the extreme temperature and pressure, rocks go through a significant chemical or physical change, turing them into metamorphic rocks.
Yes, because high heat and pressure can change slate into other metamorphic rocks.
The short answer is that they don't! For metamorphism to occur rocks require either heat, pressure or a combination of the two. Both of these conditions occur together in the mantle, however they can occur in other places to. Such as in the rocks around igneous intrusions (high temperatures and low...
Sedimentary (as in sediment) rocks are sometimes grainy, they're made when different layers of pebbles, sand and such, are all compacted together by pressure, so they usually have layers, and limestone (a sedimentary rock that dissolves in vinegar, or any type of acid) commonly contains fossils....

slate, gneiss, quartzite, and schist
Any type of rock can become metamorphic.
marble (metamorphic) reacts to hydrochloric acid.
The parent rock of serpentine is called peridotite which is an ultramafic rock
Gneiss is a metamorphic rock of variable composition with distinct banded layers. The layers or banding are called foliations, the result of the alignment of mineral grains in a direction perpendicular to the direction of pressure being exerted on the rock.
i am not sure. by mining i guess
metamorphic rocks can vary from smooth to jagged and sharp because they are caused by internal pressure inside the earth. they then come out of volcanoes
Metamorphic rocks are older sedimentary, igneous, and metamorphic changed by pressure and temperature.
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change. If you exam...
== Answer == Metamorphic rocks are either created at great depth, or at contact zones with magmatic intrusions.
== Answer == They can determine the protolith, or parent rock, by the composition of the metamorphic rock. They can also surmise the method of metamorphism.
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
granite. it's very simmilar to Gneiss but lower grade of metamorphism
== Answer == Sedimentary, igneous and metamorphic
Yes. Proximity to a heat source can be enough to cause metamorphism of rock.
no lava is a liquid that when cooled forms extrusive igneous rock Metamorphic rock is something that has been "metamorphosed" usually by being shoved down into the high temperatures and pressures inside the earth by tectonic plate movement. Sandstone (soft) can become granite (hard) in this way.
When metamorphic rock is deposited deep down in the earth, due to pressure and heat, it could be turned easily to lava. When this lava gets heated up the more, due to convection of heat it is force to come out. It cools off on the earth surface as igneous rock.
Metamorphic Rocks are used for making houses, roofs of houses, counter tops, floor tiles and is carved into statues.
there are two kinds of rocks and they are :marble, slate, gneiss, schist granite and pegmatite.
Granite is an igneous rock.
Metamorphic rock is formed deep in the Earth's crust under tremendous heat and pressure. Fossiles are formed in sedimentary rock near the surface.
By high pressure and temperature
heat and pressure create metamorphic rock.
yes came out somewhere in January
Marble is found around the world but mostly in Canada, Italy, Germany, Spain, India, America and China. It can be found in the mountains or in hot places. Marble comes from the earth. It is a type of stone
sedimentery rock being heated and squashed by other rock nd bit's of sediment.
a volcano erupting or whan a volcano cools you can dig for the rock underground
They form from all rock types. That is, from pre-existing rocks of igneous, and sedimentary origin and even from already existed metamorphic rocks.
It can still turn into a new and more recent metamorphic rock.
Metamorphic rocks are catagorized into two main types: foliated and non-foliated. Three examples of foliated metamorphic rocks are gniess, slate and schist. Some non-foliated rocks include marble, amphibolite and quartzite. Generally, metamorphic rock, and the metamorphic processes can be divided...
Quartzite is a metamorphic rock formed from sandstone.
