Which type of rock forms from an existing rock that is changed by heat, pressure, or chemical reactions?

Explanation:
Metamorphic rocks form when an existing rock is subjected to heat, pressure, or chemical reactions deep underground, causing its minerals to recrystallize and sometimes reorient without melting. This change gives the rock a new texture and mineral makeup while staying solid. For example, shale can transform into slate under directed pressure, limestone can become marble as minerals recrystallize, and granite can become gneiss with higher temperatures and pressures. The key idea is that metamorphism alters rock in place, rather than melting it to form a new kind of rock.
