Metamorphic Rock

Metamorphic rocks are formed from other types of rocks. The original rock is exposed to conditions such as heat or pressure. Carbon turning to diamonds while under extreme pressure is an example of a metamorphic rock.

Which rocks can become metamorphic rocks?

User Avatar

Asked by Wiki User

Any type of rock can become a metamorphic rock through a process called metamorphism. This includes sedimentary rocks, such as shale and limestone, as well as igneous rocks, like granite and basalt. The transformation occurs when the rocks are subjected to high heat and pressure deep within the Earth's crust.

Does pressure affect metamorphic rock?

User Avatar

Asked by Wiki User

Yes, pressure plays a crucial role in the formation of metamorphic rock. As sedimentary or igneous rock is buried deep within the Earth's crust, it is subjected to increasing pressure over time. This pressure, exerted by overlying layers of rock and the weight of the Earth's crust, causes the minerals within the rock to recrystallize, creating a new metamorphic rock with distinct texture and characteristics.

What is a metamorphic rock that starts with n?

User Avatar

Asked by Wiki User

One metamorphic rock that starts with "n" is the rock called "gneiss." Gneiss is formed from the alteration of pre-existing rocks, such as granite or sedimentary rocks, through intense heat and pressure. It is characterized by its banded or foliated appearance and can have various mineral compositions.

Asked by Wiki User

Slate pencils are typically used for writing on slate boards and are not intended for consumption. They are made from a mixture of clay and graphite. If you are looking for a culinary experience, it is recommended to explore other food options that are enjoyable and safe to eat.

What happens when metamorphic rocks are heated?

User Avatar

Asked by Wiki User

When metamorphic rocks are heated, the minerals within the rock may undergo recrystallization, transforming into new minerals. This process can lead to the development of new textures and structures in the rock. However, excessive heat can cause the minerals to melt and reform as igneous rocks.

What can change a igneous rock into a metamorphic rock?

User Avatar

Asked by Wiki User

The process that can change an igneous rock into a metamorphic rock is called metamorphism. This occurs when the igneous rock is subjected to high temperatures and pressure deep within the Earth's crust. These conditions cause the minerals in the rock to recrystallize and realign, forming a new metamorphic rock with different physical and chemical properties.

What is the shape of an metamorphic rocks?

User Avatar

Asked by Wiki User

The shape of metamorphic rocks can vary widely depending on the specific rock and the conditions under which it formed. Some metamorphic rocks, such as slate or schist, may have layered or foliated textures. Others, like marble or quartzite, are typically more massive and may have a granular or compact appearance.

Is soapstone a igneous or a sedimentary or a metamorphic rock?

User Avatar

Asked by Wiki User

Soapstone is a metamorphic rock. It is formed through the metamorphism of ultramafic rocks, such as peridotite or serpentinite. This process involves high heat and pressure, which causes the minerals in the rock to recrystallize, resulting in the formation of soapstone.

What metamorphic rock forms from sandstone?

User Avatar

Asked by Wiki User

Quartzite is the metamorphic rock that forms from sandstone. During the process of metamorphism, the sandstone is subjected to heat and pressure, causing the grains to recrystallize and fuse together, resulting in the formation of quartzite.

What is a metamorphic rock formed from limestone?

User Avatar

Asked by Wiki User

A metamorphic rock formed from limestone is known as marble. Marble is created when limestone undergoes intense heat and pressure over time, causing its minerals to recrystallize and form a new, harder rock with a characteristic crystalline texture.

Does rock melt when it is changing into metamorphic rock?

User Avatar

Asked by Wiki User

No, rock does not melt when it is changing into metamorphic rock. Metamorphic rocks form from pre-existing rocks, such as sedimentary or igneous rocks, through a process called metamorphism. This process involves changes in temperature, pressure, or the presence of fluids, which cause the minerals in the rock to recrystallize without melting.

Why was the blank Slate so popular in the early 20th century?

User Avatar

Asked by Wiki User

The blank slate was popular in the early 20th century because it aligned with the prevailing belief in social progress and the potential for human improvement. The idea that individuals were shaped solely by their environment and experiences offered hope that society could be optimized through education and social reform. Additionally, the blank slate concept provided an intellectual basis for theories of behaviorism and social engineering.

Why is slate an excellent material for pool and billiard tables?

User Avatar

Asked by Kadejahalaine

The major advantage of a slate bed pool table is that it provides a more true and even run of the balls. On other surfaces the balls are more likely to deviate from straight lines. Slate tables will also allow the balls to react better to spin.

How long does it take to form a metamorphic rock?

Asked by Wiki User

The rock cycle is the natural process in which rocks transform from one rock type into another rock type over time, a type of natural recycling.

Igneous rocks, which are formed from magma cooling underground, or lava above ground are formed from previous igneous, metamorphic, or sedimentary rocks which have become melted, usually as a result of plate collision and subduction.------->

When these igneous rocks are exposed to weathering and erosion, they break down into smaller particles that are transported by wind and water to a place of deposition, where they can form into sedimentary rock strata, through a process of lithification, where excess water is squeezed out by overburden pressures and the particles are cemented together by various minerals precipitating out of How_do_rocks_change_from_one_type_to_another_in_the_rock_cycle. Igneous and metamorphic rocks can both be turned into sedimentary rocks in this way.------->

Igneous and sedimentary rocks can also be changed by heat and/or pressure into metamorphic rocks, by transforming their existing mineral structures into new minerals or realigning the existing minerals. There are different degrees of metamorphism, so even an existing metamorphic rock can become a different metamorphic rock. -------->

If these metamorphic rocks are melted, then solidify, they become igneous rocks, and the cycle starts all over again.

The rock cycle is largely driven by lithospheres plate movements which cause subduction and uplift, also by climatic conditions and the associated erosion elements.

How do you classify rocks?

User Avatar

Asked by Wiki User

Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.

What role does heat play in creating new minerals or new crystalline structures in metamorphic rocks?

User Avatar

Asked by Wiki User

The heat comes from magma that is deep inside the earth, sedimentery rock is heated and squashed into metamorphic rock.

When metamorphic rock melts turns into?

Asked by DarrylTrurelgioncrosbyfb1015

Metamorphic rock that melts turns to magma. This only becomes lava if it is erupted to the surface in a volcano.

What term is used to describe metamorphic rocks with a banded texture?

User Avatar

Asked by Wiki User

The two main groups of metamorphic rocks are foliated and non-foliated. Foliated metamorphic rocks show layering and parallel alignment of flat mineral crystals (ex. micas). The "banded texture in metamorphic rocks" is one of the specific kinds of foliated textures. It is referred to as gneissic banding. Essentially, this texture displays alternating layers of light and dark minerals. These rocks are called gneiss- the light bands form from quartz and feldspars, while the dark ones form from ferromagnesian minerals.

because they are broken off into little bits and so get smaller and gradually worn down
