Here are some places where quartz is found:
* Continental crust: Quartz is a major component of granite and other igneous and metamorphic rocks that make up the Earth's crust.
* Sand: Beaches and deserts are filled with quartz sand, which is formed by the weathering and erosion of quartz-rich rocks.
* Sedimentary rocks: Quartz is also found in sedimentary rocks like sandstone, which are formed from compacted sand.
