Citrines belong in the quartz family. Citrine is the name for quartz that is yellow, greenish-yellow, brownish-yellow or orange. The name is derived from "citron" which is the name of a yellow fruit.
Diamond belong to the Igneous rock group!!
Slate is a low-grade metamorphic rock.
Sedimentary Rocks because chalk is pretty much limestone.
The most abundant minerals belong to the silicate mineral group, which are composed of silicon and oxygen atoms. Examples include quartz, feldspar, and mica.

the answer to the is sedementary
Diamond belong to the Igneous rock group!!
Igneous
It is a sedimentary rock.
Slate is a low-grade metamorphic rock.
I believe it belongs to the group Halides.
Sedimentary Rocks because chalk is pretty much limestone.
The most abundant minerals belong to the silicate mineral group, which are composed of silicon and oxygen atoms. Examples include quartz, feldspar, and mica.
