Question
All metamorphic rocks are created in the presence of high heat and high pressure.Group of answer choicesTrueFalse
Solution
A. True
Metamorphic rocks are indeed formed through the process of metamorphism, which involves the transformation of existing rock types in a process called metamorphism, which means "change in form". This process happens due to changes in heat and pressure over a long period of time. The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (1500 bars), causing profound physical and/or chemical change. So, it's true that all metamorphic rocks are created in the presence of high heat and high pressure.
