A metamorphic rock is an igneous, sedimentary, or another metamorphic rock that has been: 1) squeezed by incredible pressures deep underground, 2) has been exposed to very hot fluids, 3) has been exposed to very high temperatures without melt occurring, 4) combinations of numbers 1-3. Rock exposed to these conditions can be metamorphosed, altering its structure, mineral alignment, and possibly its chemistry.

It can undergo more metamorphism, creating a different metamorphic rock, or undergo retrograde metamorphism, which also creates a different metamorphic rock. Metamorphic rocks can undergo these changes due to increases or decreases in temperature and pressure.

The parent rock is exposed to varying degrees of pressure and/or heat either from depth of burial, exposure to a plutonic body of intense heat, or from pressures resulting from the collision of tectonic plates. The heat and/or pressure can transform the minerals inside the parent rock to new minerals, cause recrystallization of existing minerals, or reorganize the existing minerals into bands and layers. Exchanges of elements can also occur from hot fluids associated with plutonic intrusions. All of these processes take place without any melting of the parent rock.

Nobody knows, unless they are smart so i am but I'm not gonna answer it because you need to read your science book to figure it out

What rocks change into metamorphic rocks?

Any type of rock can become metamorphic.


Can metamorphic rocks from from other metamorphic rocks?

Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.


What type of rocks are metamorphic rocks formed from?

Any rock can become a metamorphic rock. To become a metamorphic rock the rock must undergo heat and/or pressure, but not so much that the rock melts. Should the rock melt it would become an igneous rock.


Do rocks change from one type to another or not change at all?

Rocks are constantly changing types. The three types are metamorphic, sedimentary and igneous. Igneous rocks are created when magma or lava cools and solidifies. Metamorphic rocks are created when rocks are put under high pressure and high heat, which compacts the molecules in the rocks. Sedimentary rocks are created when small particles of rocks accumulate in an area and are cemented together via pressure or chemical change. Therefore, sedimentary and igneous rocks can become metamorphic rocks if they are buried deep in the earth's crust. Metamorphic and sedimentary rocks can become igneous rocks if they are melted then resolidify from the magma or lava. Metamorphic and igneous rocks can become sedimentary rocks if they are chipped into tiny pieces then accumulate together and become cemented.


How can igneous metamorphic and sedimentary rocks become metamorphic rocks?

Im learning this in school, and the answer is look for a "rock cycle" and that answers all questions like yours :)

What type of rocks can be changed into metamorphic rocks?

Any type of rock can become metamorphic.


How do igneous rock become metamorphic rocks?

Metamorphic rocks become igneous rocks by melting from heat and pressure, remnants of which may cool from melt (magma) and become components of igneous rock.


What rocks are formed from high temperature and pressures?

Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.


Can an igneous rock become metamorphic?

Yes,so can sedimentary rocks and even other metamorphic rocks.


Do sedimentary rocks melt and become magma?

No. It's the Metamorphic rocks that melt and become magma.


What rocks change into metamorphic rocks?

Can metamorphic rocks be changed into other types of metamorphic rocks?

Yes, when the metamorphic rock melts and becomes magma there is a chance that it can become a new type of rock.


Do igneous rocks directly become metamorphic rock?

no


When rocks are metamorphosed the pressure causes them to become what?

Deformed, and change into metamorphic rocks.

I think you are looking for the term "Metamorphic".
