Climate and the type of rock
Quartz is a mineral, not a rock.
Quartz.

Granite

Climate and the type of rock
technically, quartz is not a rock. it is a mineral. quartz can be found in any type of rock
Granite is a solid, an igneous rock containing the minerals feldspar, quartz, mica, and inosilicates.
Sand forms sedimentary rocks such as sandstone. Sandstone containing mostly quartz can form the metamorphic rock quartzite.
Quartz is a mineral composed of silicon and oxygen, SiO2.
== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
