Metamorphic rocks are either created at great depth, or at contact zones with magmatic intrusions.

Metamorphic rocks are made deep within the Earth's crust or upper mantle where high temperatures and pressures cause the original minerals in existing rocks to recrystallize and form new minerals. This process typically occurs several kilometers below the Earth's surface.

What type of rocks can contain fossils on them?
Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
What will determine if a rock becomes an igneous or metamorphic rock?
Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
From what is metamorphic rock made?
Metamorphic rocks are made from pre-existing rocks that have been altered by heat, pressure, and/or chemical processes within the Earth's crust. These changes cause the minerals and textures of the original rock to recrystallize, forming a new rock with different properties.
Changed-over rocks are called?
Metamorphic Rocks
Why is metamorphic rock hard?
because a metamorphic rock is made up of different rocks.
Is metamorphic rocks made up of sedimentary rock igneous rock or other metamorphic rocks?
Metamorphic rocks
Is gneiss metamorphic?
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
Are tombstones made from metamorphic rocks?
They can be if that is what you what one to be made from.
How are foliated metamorphic rocks different from nonfoliated metamorphic rocks?
Foliated are made of interlocking crystals, non-foliated are not.
What type of rock are mountains made of?
Igneous rocks, Sedimentary rocks Metamorphic rocks.
Rocks made when other rocks are subjected to intense pressure and heat?
Metamorphic rocks are formed when existing rocks are subjected to high pressure and temperature deep within the Earth's crust. This process causes the minerals in the original rocks to recrystallize into new forms, resulting in metamorphic rocks like marble, slate, and gneiss.
What type of rocks can contain fossils on them?
Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
What is one way igneous sedimentary and metamorphic rocks are different?
igneous rocks are made of lava that cools and hardens and metamorphic rocks are madeby heat and pressure.
What metamorphic rocks formed fom?
Metamorphic rocks are made by the action of heat and pressure on pre-existing rocks. e.g. Schist, Coesite, most micas.
What are metamorphic rocks made?
preexisting rocks that have been metamorphosed by cooking and crushing.
How is metamorphic rocks organically made?
rocks pile on other rocks pushing them downward, as they reach about one eighth of the way towards the mantle the pressure and heat make metamorphic rocks
What will determine if a rock becomes an igneous or metamorphic rock?
Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
