- Exposure to pressure is a kind of condition
- Exposure to heat is a kind of condition
- Therefore, exposure to heat and pressure are kinds of conditions

- Exposure to heat and pressure are kinds of conditions
- If something is formed by certain conditions then that something will likely be formed in an area with those conditions
- Hence, if something is formed by being exposed to heat and pressure then that something will likely be formed in an area with heat and pressure

- Great can mean high in value
- Extreme means very high in value
- Hence, extreme can mean great

- Extreme can mean great
- Metamorphic rocks are formed by rocks being exposed to extreme heat and pressure
- Hence, metamorphic rocks are formed by being exposed to great heat and pressure

- If something is formed by being exposed to heat and pressure then that something will likely be formed in an area with heat and pressure
- Metamorphic rocks are formed by being exposed to great heat and pressure
- Hence, metamorphic rock will likely be formed in an area with great heat and pressure

- As rocks are buried deeper below other rocks , the pressure / heat on that rock will increase
- Underground means buried deep below other rocks
- Therefore, as rocks are buried deeper underground, the pressure / heat on that rock will increase

- As rocks are buried deeper underground, the pressure / heat on that rock will increase
- Deep means great in depth
- So, if a rock is buried deep underground then the pressure / heat on that rock will be great

- Metamorphic rock will likely be formed in an area with great heat and pressure
- If a rock is buried deep underground then the pressure / heat on that rock will be great
- So, metamorphic rock is likely to be formed in an area deep underground

- Metamorphic rock is likely to be formed in an area deep underground
- A site is a kind of area
- Therefore, metamorphic rock is likely to be formed in a site deep underground

So, metamorphic rock is likely to be formed in a site deep underground
