Final answer:
Pearls, jet, amber, and coal are not minerals because they do not meet the criteria of being inorganic solids with a definite chemical composition and an orderly atomic arrangement.
Step-by-step explanation:
Pearls, jet, amber, and coal are not considered minerals because they do not meet the criteria of being inorganic solids with a definite chemical composition and an orderly atomic arrangement. Pearls are formed inside the shells of mollusks and are composed of layers of calcium carbonate. Jet is a type of coal that is formed from fossilized wood and is not a mineral because it is organic in nature.
Amber is fossilized tree resin and is also not a mineral because it is organic. Coal is a combustible black or brownish-black sedimentary rock that is primarily composed of carbon, and although it may contain some minerals, it is not considered a mineral itself.
