All metamorphism (in Geological terms) requires heat, whether it is Thermal or Regional:
The rock that forms on earth's surface is extrusive rock or otherwise known as a metamorphic rock.
Metamorphic in a sentence
Metamorphic rock forms deep below the Earth's surface where high pressure and temperature conditions exist. These conditions are not typically found at the Earth's surface where weathering, erosion, and lower temperatures prevail. As a result, metamorphic rock is rarely formed at the Earth's surface.
A rock that forms from other rocks due to heat and pressure beneath the Earth's surface is called a metamorphic rock. Examples include marble, slate, and gneiss.
metamorphic slate
metamorphic rock
heat and pressure beneath Earth's surface can change a rock into metamorphic rock.
Metamorphic rock forms when existing rock is subjected to high temperatures and pressures below the Earth's surface. This causes the mineral composition and texture of the rock to change, resulting in the formation of new types of rock such as marble, schist, or gneiss.
