Expert Solution & Answer
Answer to Problem 1GST
Gold nugget, ruby, quartz, and glacial ice are minerals; seawater, obsidian, cubic zirconia, and amber are not considered as minerals, as they do not fit the criteria of being a mineral.
Explanation of Solution
“A mineral is an inorganic, naturally occurring solid formed by geological processes, possessing a crystalline structure and a definable chemical composition.”
- a) Gold nugget - Gold is an example of a mineral, classified as a native element.
- b) Seawater is not a mineral because minerals by definition are solids.

- d) Ruby is a mineral. It is a gemstone variety of mineral corundum.
- e) Quartz is a mineral.
- f) Glacial ice is a mineral, as it meets all of the criteria of a mineral.

- h) Amber is not a mineral since it has an organic origin.
