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 are the visual characteristics that distinguish a metamorphic rock from other types of rocks, and how does a metamorphic rock typically appear in terms of its physical features and textures?
Metamorphic rocks are distinguished by their unique textures and structures, which are formed through intense heat and pressure. These rocks often have distinct layers or bands, known as foliation, and may contain minerals that have been rearranged or recrystallized. In terms of physical features, metamorphic rocks can appear shiny, smooth, and sometimes have a striped or swirled pattern. Their textures can range from fine-grained to coarse-grained, depending on the specific conditions under which they were formed.

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.
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.
