Metamorphic Rocks Identification
Metamorphic rocks are formed when existing rocks (igneous, sedimentary, or even other metamorphic rocks) are transformed by heat, pressure, or chemical reactions, without melting. The question asks to identify the option that is NOT a metamorphic rock.
Analyzing Rock Types
- Granite: This is an igneous rock. It forms from the slow cooling of magma deep beneath the Earth's surface.
- Quartzite: This is a metamorphic rock. It is formed when sandstone is subjected to heat and pressure.
- Gneiss: This is a metamorphic rock, often characterized by visible bands of different minerals. It typically forms from high-grade metamorphism of rocks like granite or sedimentary rocks.
- Schist: This is also a metamorphic rock, known for its foliated or layered structure, caused by minerals aligning under heat and pressure.
Conclusion on Metamorphic Rocks
Based on the analysis, Granite is an igneous rock, not a metamorphic rock. Quartzite, Gneiss, and Schist are all examples of metamorphic rocks.
Therefore, the correct option is Granite.
