Heat and Pressure
Metamorphic rocks form when existing rocks undergo changes in temperature and pressure due to processes such as tectonic plate movement, burial deep within the Earth's crust, or contact with hot intrusions. These changes cause the minerals in the existing rocks to recrystallize and reorganize, leading to the formation of metamorphic rocks.
The physical processes important in transforming sedimentary rocks to metamorphic rocks are, Pressure, Temperature, Stress, Depth of burial and Metasomatism.
Some questions about metamorphic rocks that could be explored include: How do different types of pressure and temperature affect the formation of metamorphic rocks? What are the key minerals found in metamorphic rocks and how do they indicate the rock's history? How do metamorphic rocks differ from igneous and sedimentary rocks in terms of their formation processes and characteristics?
Geologic processes that assist in the formation of metamorphic rock include heat and pressure from deep within the Earth's crust, as well as the presence of chemically active fluids that can alter the mineral composition of existing rocks. These processes can cause changes in the texture, structure, and mineralogy of the rocks, resulting in the formation of metamorphic rocks.
Parent rocks of metamorphic rocks can include igneous, sedimentary, or pre-existing metamorphic rocks. These rocks undergo changes in mineralogy and texture due to heat, pressure, and chemical processes without melting, resulting in the formation of metamorphic rocks. Different parent rocks can give rise to different types of metamorphic rocks.
Weathering can break down metamorphic rocks into smaller fragments through physical and chemical processes, leading to the formation of sediment. This sediment can then become compressed and cemented to form sedimentary rocks. Additionally, weathering can alter the mineral composition and texture of metamorphic rocks, changing their original characteristics.
Heat is always present in the formation of metamorphic rocks.
Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
No. Heat from the interior of the Earth trying to reach the surface drives lithospheric plate movements which are mostly responsible for the formation of igneous and metamorphic rocks.

These scientists are called petrologists. They examine the mineral composition, texture, and structure of rocks to understand their formation processes, such as magmatic, sedimentary, or metamorphic origins. By analyzing these physical properties, petrologists can unravel the geological history of rocks.
