Metamorphic is an adjective that describes rocks that have been transformed by heat, pressure, or chemical reactions. This transformation happens deep within the Earth's crust or where tectonic plates collide. Here's a breakdown:
* Metamorphism: The process of changing existing rocks into new types of rocks through heat, pressure, and/or chemical reactions.
* Metamorphic rocks: Rocks that have been transformed from their original state through metamorphism.
Examples of metamorphic rocks:
* Marble: Formed from limestone.
* Slate: Formed from shale.
* Gneiss: Formed from granite.
* Quartzite: Formed from sandstone.
