heat and pressure
Subduction and high pressure.
Metamorphic Rocks are rocks that have changed form due to heat and pressure.
Metamorphic rocks are formed when existing rocks, either sedimentary or igneous, are subjected to intense pressure and heat deep within the Earth's crust. This process causes the rocks to undergo physical and chemical changes, resulting in the formation of new minerals and textures characteristic of metamorphic rocks.
Metamorphism is the process where existing rocks are changed by heat, pressure, or fluids. This process causes the minerals in the rocks to rearrange and form new crystals, creating metamorphic rocks.
The physical processes important in transforming sedimentary rocks to metamorphic rocks are, Pressure, Temperature, Stress, Depth of burial and Metasomatism.
Hot
no, the process only happens to igneous rocks
Weathering and erosion can break down igneous and metamorphic rocks into smaller pieces, which are then transported and deposited as sediments. This process involves physical and chemical breakdown of the rocks due to exposure to the elements and natural forces like wind, water, and ice.
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.
One way that sedimentary and igneous rocks can be transformed into metamorphic rocks is through the process of heat and pressure. When these rocks are subjected to intense heat from nearby magma or geothermal processes, along with significant pressure from tectonic forces, their mineral structures can change, resulting in the formation of metamorphic rocks. This process, known as metamorphism, alters the physical and chemical properties of the original rock without melting it.
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
