Probably a felsic igneous rock.
Neither. Quartzite is metamorphosed quartz sandstone, and is therefore a metamorphic rock.
Sandstone
Probably orthoquartzite, although some consider it a metamorphic rock.
Cooling and solidifying magma turns into igneous rock.
Sandstone can metamorphose into quartzite.
Quartzite is a metamorphic rock.
Neither. Quartzite is metamorphosed quartz sandstone, and is therefore a metamorphic rock.
It doesn't. Granite is an igneous rock, not metamorphic. However, quartzite is metamorphic and is made from sandstone.
Sandstone
Quartzite is metamorphosed quartz sandstone. Basalt is an extrusive igneous rock.
Probably orthoquartzite, although some consider it a metamorphic rock.
granite
Cooling and solidifying magma turns into igneous rock.
Metamorphic rock becomes igneous rock when it is melted, then solidifies.
An igneous rock is formed when magma rises through the earth's crust and cools.
The minerals in sandstone recrystallize when granite first turns into sandstone a gritty sedimentary rock under weathering and erosion and then into the metamorphic rock quartzite under heat and pressure and then it goes all the way throughout the rock cycle and back into its original form of granite a igneous rock and is formed when magma recrystallizes.
Obsidian is an extrusive igneous rock, formed from rapidly cooling lava.
