heat and pressure.
Heat and pressure are the two key components.
Sedimentary and igneous rocks can be transformed into metamorphic rocks through two primary processes: heat and pressure. Elevated temperatures, often due to tectonic activity or proximity to magma, can alter the mineral composition and structure of the rocks. Additionally, intense pressure, typically from overlying rock layers or tectonic forces, can cause physical and chemical changes, resulting in metamorphism. Together, these processes create new mineral assemblages and textures characteristic of metamorphic rocks.
Metamorphic rocks are formed from igneous, sedimentary and older metamorphic rocks that are introduced to extreme temperature and pressure. Because of the extreme temperature and pressure, rocks go through a significant chemical or physical change, turing them into metamorphic rocks.

Slate and marble are examples of metamorphic rocks. Other metamorphic rocks include gneiss, schist, and quartzite. All metamorphic rocks are formed from other rock types.
Metamorphic rocks can be categorized into two main categories: foliated and non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of mineral grains, while non-foliated metamorphic rocks lack this layered structure.
The two groups of metamorphic rock are foliated and nonfoliated. Metamorphic rocks can also be classified as contact and regional.
Those are two types of metamorphic rocks. Banded metamorphic rocks are when rocks layer into layers and they look like strips or Bands. Non banded is the opposite of banded
Sedimentary and metamorphic rocks.
To form a metamorphic rock, two key factors are needed: heat and pressure. These conditions alter the mineral composition and structure of pre-existing rocks (igneous, sedimentary, or even other metamorphic rocks) without melting them. Additionally, the presence of chemically active fluids can facilitate mineral changes during the metamorphic process.
