Metamorphic rock | Definition, Formation, Facts | Britannica Metamorphic rock, any rock that results from the alteration of preexisting rocks in response to changing conditions, such as variations in temperature, pressure, and mechanical stress, and the addition or subtraction of chemical components
Metamorphic Rocks – Definition, Formation, Types, Examples Metamorphic rocks form due to the transformation of preexisting rocks in response to environmental changes such as heat, high pressure, and mechanical stress The parent rock can be sedimentary, igneous, or even a different sort of metamorphic rock
What are metamorphic rocks? | U. S. Geological Survey Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors Conditions like these are found deep within the Earth or where tectonic plates meet
