- Exposure to extreme heat and pressure changes sedimentary rock into metamorphic rock
- If something changes into something else then that something else is formed from that something
- Hence, 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
- Therefore, metamorphic rock is formed from sedimentary rock being compacted, heated, and recrystallized

- Metamorphic rock is formed from sedimentary rock being compacted, heated, and recrystallized
- Limestone is a kind of sedimentary rock
- So, metamorphic rock is formed from limestone being compacted, heated, and recrystallized

- Metamorphic rock is formed from limestone being compacted, heated, and recrystallized
- Marble is a kind of metamorphic rock
- Therefore, marble is formed from limestone being compacted, heated, and recrystallized

Therefore, marble is formed from limestone being compacted, heated, and recrystallized
[Question]Which type of rock is formed from limestone that has been compacted, heated, and recrystallized?
