Metamorphic rock is formed through the transformation of existing rocks—either igneous, sedimentary, or other metamorphic rocks—under high temperature and pressure conditions within the Earth's crust. This process, known as metamorphism, alters the mineral composition and texture of the rock without melting it. Factors such as heat, pressure, and chemically active fluids contribute to the changes, resulting in various types of metamorphic rocks, such as schist, gneiss, and marble.
