What rock forms by pressure on large masses of rock?
Metamorphic rock forms by the pressure on large masses of rock, causing the existing minerals in the rock to recrystallize without melting, resulting in new minerals and textures. Examples of metamorphic rocks include marble, slate, and schist.
What causes foliates metamorphic textures?
Heat, along with applied pressures, either from depth of burial or from tectonic forces on rock.
What new kind of rock is formed when sedimentary rock is subject to heat and pressure?
When sedimentary rock is subjected to heat and pressure, it can transform into metamorphic rock. This process typically occurs deep within the Earth's crust and can result in the recrystallization of minerals and the development of new textures and structures in the rock. Examples of metamorphic rocks include marble, slate, and schist.
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.
Is metamorphic rock rough?
Metamorphic rocks can have a range of textures, from smooth to rough, depending on the minerals present and the intensity of the metamorphic processes they underwent. Some metamorphic rocks, like gneiss, can have a rough texture due to the presence of minerals like quartz and feldspar.
Does Metamorphic rock has different kinds of textures?
Yes
What is a changed rock in 2 words?
metamorphic rock
What rock forms by pressure on large masses of rock?
Metamorphic rock forms by the pressure on large masses of rock, causing the existing minerals in the rock to recrystallize without melting, resulting in new minerals and textures. Examples of metamorphic rocks include marble, slate, and schist.
What are the associated rocks and their textures?
Magmatic fluids coming from the intrusive rock may also take part in the metamorphic reactions.
What causes foliates metamorphic textures?
Heat, along with applied pressures, either from depth of burial or from tectonic forces on rock.
What do different rock textures of metamorphic rock reflect?
Different rock textures of metamorphic rock reflect the varying conditions under which the rock was formed, such as temperature, pressure, and presence of fluids. For example, foliated textures like schist or gneiss indicate directional stress during formation, while non-foliated textures like marble suggest uniform pressure and recrystallization.
What new kind of rock is formed when sedimentary rock is subject to heat and pressure?
When sedimentary rock is subjected to heat and pressure, it can transform into metamorphic rock. This process typically occurs deep within the Earth's crust and can result in the recrystallization of minerals and the development of new textures and structures in the rock.

What condition change igneous sedimentary to metamorphic rock?
The conditions that change igneous or sedimentary rock into metamorphic rock include high temperature, high pressure, and the presence of chemically active fluids. These conditions cause the minerals in the original rock to recrystallize, forming new minerals and textures characteristic of metamorphic rocks.
Does igneous rock have to become sedimentary rock before it can become metamorphic rock?
No, igneous rock can undergo metamorphism without becoming sedimentary rock first. Metamorphism can occur in any rock type (igneous, sedimentary, or metamorphic) when exposed to high temperature and pressure, leading to the formation of new minerals and textures.
What type of rock can be either foilated or non-foliated?
Metamorphic rock can be either foliated or non-foliated. Foliated metamorphic rocks have layered or banded textures, while non-foliated metamorphic rocks lack these layers and have a more uniform appearance. Examples of foliated metamorphic rocks include schist and gneiss, while examples of non-foliated metamorphic rocks include marble and quartzite.
