9 some scientists actually consider the exosphere as part of outer space as there is such a gradual and fuzzy distinction between the density of molecules in the very upper reaches of the atmosphere and lower reaches of space
Notice that graphite, commonly seen in pencil lead, and diamonds. have the same chemical formula. Minerals with the same chemical formula but. different crystal structures are called polymorphs. These minerals have different. types of chemical bonds and, thus, different crystal forms. If a substance fails any part of this definition, it is not a mineral. For example, table sugar, an organic compound formed by biological plant activity, fits all. facets of the definition except the inorganic part.
Minerals are naturally occurring chemical compounds that have a solid, crystalline structure, meaning they're arranged in unique geometric patterns at the atomic level. Minerals are also inorganic; they're not formed from amino acids, peptides, or enzymes, as living things are.inerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.
