All metamorphic rocks are created in the presence of high heat and high pressure.Group of answer choicesTrueFalse

Answer Analysis

1. Understanding Metamorphic Rocks: Metamorphic rocks are formed from existing rocks (igneous, sedimentary, or other metamorphic rocks) that have undergone transformation due to high heat, high pressure, or both.

2. High Heat and High Pressure: The conditions of high heat and high pressure are typically associated with tectonic activities, such as subduction and mountain building processes, which can change the mineral composition and structure of the original rocks.

3. Conclusion: As the statement suggests that "all metamorphic rocks are created in the presence of high heat and high pressure," it is true in the context that these factors are necessary for the metamorphic process.

Final Answer

True. All metamorphic rocks are indeed created in the presence of high heat and high pressure.
