Metamorphic foliated rocks form under conditions of high pressure and temperature, typically within the Earth's crust. As pre-existing rocks (either igneous, sedimentary, or other metamorphic rocks) undergo metamorphism, their minerals are realigned due to differential stress, creating a layered or banded appearance. This alignment occurs as minerals such as mica, schist, and gneiss develop parallel orientation, resulting in the characteristic foliation. The process often involves recrystallization, where minerals change in size and shape without melting.

What are sone examples of metemorphic rock?
Some examples of metamorphic rocks include marble, slate, schist, and gneiss. These rocks are formed from the alteration of existing rocks due to high pressure and temperature underground.
What process found at a convergent boundary will help form a metemorphic rock?
At a convergent boundary, the process of subduction plays a critical role in forming metamorphic rocks. As one tectonic plate is forced beneath another, it encounters increased pressure and temperature conditions, leading to metamorphism of the rocks involved. Additionally, the intense heat and pressure can cause existing rocks to recrystallize and change their mineral composition, resulting in the formation of various types of metamorphic rocks.
What rocks form as melted rocks?
igneous
What materials form Metamorphic Rocks?
Metamorphic rocks can form from the transformation of pre-existing rocks under high temperatures and pressures. Common parent rocks include shale, limestone, and granite. The minerals present in the parent rocks determine the types of metamorphic rocks that can form.
What is the difference between exclusive and intrusive rocks?
There is no such thing as an "exclusive" rock. However, there are extrusive rocks. These are divisions of igneous rocks, or rocks that form from molten rock. Intrusive rocks form from molten rock that has cooled underground. They can also be called plutonic rocks. Extrusive rocks, also called volcanic rocks, form from molten rock that has formed at or above the surface.
How do metemorphic rocks form?
they form by heat and presssure
What are the sources of heat that helps metemorphic rocks form?
Frictional heat, radioactive disintegration/decay, magmatic heat, geothermal gradient, load-pressure effect.
What are sone examples of metemorphic rock?
Some examples of metamorphic rocks include marble, slate, schist, and gneiss. These rocks are formed from the alteration of existing rocks due to high pressure and temperature underground.
What are some examples of metemorphic rock?
Metamorphic rocks are igneous or sedimentary rocks that have been transformed by great heat or pressure caused by movement in the Earth's crust.Examples include schist, gneiss, and slate

What is metemorphic rock used for?
Metamorphic rocks are used for so many different things. They are commonly used to make slate which is used for roofing and marble which is used t make counter tops among other uses.
Can metamorphic rocks can form from igneous but not from sedimentary rocks?
Metamorphic rocks can form from both igneous and sedimentary rocks
Can Metamorphic rocks can form from igneous but not from sedimentary rocks.?
Metamorphic rocks can form from both igneous and sedimentary rocks
Is a igneous rock marble?
No. Marble is a Metamorphic rock.
