Which type of rock are quartzite, schist and marble?
Answer Details
Quartzite, schist, and marble are all examples of metamorphic rocks. Metamorphic rocks are formed from pre-existing rocks (either igneous, sedimentary, or other metamorphic rocks) that have been subjected to high pressure, temperature, or both. These conditions cause the minerals and texture of the original rock to change, forming a new rock with different physical and chemical properties. Quartzite, schist, and marble are all formed by different degrees of metamorphism, which is why they have distinct characteristics and are classified as separate types of metamorphic rock.
