Sedimentary rocks when altered by heat and pressure because metamorphic rock. But please read the rock cycle you will see the different stages because Igneous can also become Metamorphic with intense pressure and heat.
metamorphic rock
Rock can be changed into metamorphic rock by heat and pressure.
When sedimentary rock is changed by heat and pressure, it forms metamorphic rock. This process is known as metamorphism, where the existing rock undergoes changes in mineral composition and texture without melting.
gneiss
Metamorphic rock forms when existing rock is subjected to intense heat, pressure, or chemically active fluids, causing it to recrystallize and form new minerals. This process can transform existing rock types like sedimentary or igneous rocks into metamorphic rocks like marble, slate, or schist.
