exposure to extreme heat and pressure changes sedimentary rock into metamorphic rock & if something rotation into something else then that something else is formed from that something ->  metamorphic rock is formed from sedimentary rock  metamorphic rock is formed from sedimentary rock & the formation of metamorphic rock is a sequential process, with stages of rock being compacted, heated, recrystallized -> metamorphic stone is formed from sedimentary stone being compacted, heated, and recrystallized metamorphic rock is formed from sedimentary rock being compacted, heated, and recrystallized  metamorphic rock is formed from sedimentary rock being compacted, heated, and recrystallized & effect is a mean of sedimentary stone -> metamorphic rock is formed from limestone being compacted, heated, and recrystallized metamorphic rock is formed from limestone being compacted, heated, and recrystallized  metamorphic rock is formed from limestone being compacted, heated, and recrystallized & angles is a mean of metamorphic stone -> marble is formed from limestone being compacted, heated, and recrystallized
