The 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 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 rock can be broken into fragments that may later form sedimentary rocks?
Any rock (igneous, sedimentary or metamorphic) may be broken into fragments that may later be formed into sedimentary rock.
Is a sedimentary rock or a metamorphic rock harder to sculpt?
Metamorphic rocks are formed from sedimentary and igneous rocks. When sedimentary or igneous rock is subjected to heat and pressure, the rock gets compressed. Therefore, if you had the same amount of metamorphic rock and sedimentary or igneous rock, the metamorphic rock would be heavier, because there is more 'stuff' in the metamorphic rock. ---------------------------------------------- However please note: There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.
What rock makes up the greatest part of metamorphic rock's?
may be ignoious rock by violent valconic eruption due to high pressure and low tempresure
Can pebbles change into igneous metamorphic and sedimentary rocks?
No. It's too late.Unless it gets eroded itself and eventually forms layers of sediment which may then get turned into rock.
Describe how an igneous rock may become transformed into other rock types and back into igneous rock?
Describe how an igneous rock may become transformed into other rock types and back into igneous rock? The Igneous Rock would have to go through many stages known as the Rock Cycle. The Rock Cycle steps would be: Igneous Rock than it would have to go threw erosion to become a Sedimentary Rock than it would have to go through Heat and Pressure to become a Metamorphic Rock. Then The Metamorphic Rock would have to go through melting to become a Molten Rock (Lave/Magma). Then finally it would have to go through cooling to become a Igneous Rock again<3[: ---♥PandaBabby69♥
Is tuff foliated?
No. Tuff may have depositional layers, but this is not the same as foliation, which is a charactersitic of metamorphic rock.
Is a migmatite foliated or non foliated metamorphic rock?
Difficult to give you a precise answer, migmatites are composed of a leucosome which is new material crystallized from incipient melting and a mesosome which is old material that resisted melting. These two materials may form a fine fabric which imparts a foliation to the rock. The leucosome may also be incoherently folded. Also if the migmatite is forming from a foliated source, the foliation may persist. Thus migmatites are metamorphic rocks that show characteristics of incipient melting and they may or may not show a foliation too, the foliation is not a critical characteristic of a rock being a migmatite.
How do you determine if a rock is igneous sedimentary or metamorphic?
Speaking in very general terms, and with plenty of exceptions, igneous rock may possess larger visible crystals (granite), may be glassy (obsidian), may have air pockets or bubbles present (pumice), and may be dark green or black-ish (basalt). Sedimentary rock may display sediment layers (like shale), may contain fossils (fossiliferous limestone), and may be fine grained (chemical limestone). Metamorphic rock may display foliation (parallel layers of light and dark minerals)(like gneiss), may have a wavy appearance to the foliation, have platy cleavage, or sparkle from the mineral mica (mica schist).
What type of grains does metamorphic rock have?
Metamorphic rock may have coarse, flattened, or aligned mineral grains.
If a rock becomes a metamorphic rock no other changes in the rock cycle will occur true or false?
False. The rock may undergo further metamorphism, or it may melt and re-solidify into igneous rock, or it may be broken down into sediment at the surface and later become sedimentary rock.
If a rock becomes a metamorphic rock no other changes in the rock cycle will occur.?
False A+
Which properties of a rock may change as the rock become metamorphic?
crust deeper rock
What type of rock may sedimentary rock turn into?
Metamorphic or new sedimentary rock.
What is the description of a rock?
This may not be as correct but, marble is a white color. It is a metamorphic rock.
Is it true the rock cycle is a process that is always occurring?
Its false because the rock cycle may go anyway a sedimentary rocks may turn into a metamorphic or igneous rock a igneous rock may turn Into sedimentary or metamorphic and so on
A metamorphic rock is from where?
Metamorphic rock usually forms when a rock is altered under heat and pressure without melting. Some rocks may be metamorphosed by contact with hot water,
How may metamorphic rocks be formed from sedimentary rocks?
During a mountain building phase, the sedimentary rocks may be buried deeply and subjected to heat and pressure causing certain minerals to form which were not present in the original rock. Also, an igneous intrusion may cause adjoining sediments to be altered in a contact metamorphism leading minerals such as garnets to form.
