When sedimentary rock is exsposed to heat and pressure what happends?

Answer 1

When sedimentary rock is exposed to heat and pressure, it undergoes a process called metamorphism, resulting in the formation of metamorphic rock. The increased temperature and pressure cause the minerals within the sedimentary rock to recrystallize and align, altering its texture and composition. This transformation can lead to the development of new minerals and structural changes, producing rocks like schist or gneiss from shale or limestone, respectively.
