Pressure from weight of overlying rock.
contact metamorphism, regional metamorphism, dynamic metamorphism
The three agents of metamorphism are heat, pressure, and chemically active fluids. Heat is responsible for increasing temperature, pressure for increasing stress and confining pressure, and chemically active fluids for introducing new minerals through the process of metamorphism.

The most important agents of metamorphism are heat, pressure, and chemically active fluids. Heat causes minerals to recrystallize, pressure reorients mineral grains, and chemically active fluids introduce new elements to form new minerals. Together, these agents drive the changes in rock composition and texture during metamorphism.
The rock undergoes metamorphism, where intense pressure and heat cause its mineral composition and texture to change without melting. This process can result in the formation of new minerals and reorganization of existing ones, leading to the development of metamorphic rocks like marble or slate.

Heat and pressure.
Metamorphism can occur through contact metamorphism, where rocks are altered by heat from nearby magma; regional metamorphism, where rocks are subjected to high pressure and temperature over a large area; burial metamorphism, where rocks are subjected to increased pressure from being buried deep underground; and dynamic metamorphism, where rocks are deformed under high pressure but low temperature conditions along faults or shear zones.
Metamorphism typically involves three stages: prograde metamorphism, in which rocks are subjected to increasing temperature and pressure causing mineral changes; peak metamorphism, where rocks reach their maximum temperature and pressure conditions; and retrograde metamorphism, where rocks begin to cool and the minerals may change back to their original forms.
The metamorphism caused by extreme heat and pressure is known as regional metamorphism. When a meteorite collides with the Earth, it can create impact metamorphism in the surrounding rocks, characterized by high pressures and temperatures from the impact event.

Metamorphism is a PROCESS. metamorphism is the process of change that occurs to rocks when they are subject to heat, pressure or both.
Contact metamorphism is the process of forming rocks from the heat of magma intrusion. Regional metamorphism, meanwhile, is the process of forming rocks by pressure and heat at plate boundaries.
