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.
There are a variety of characteristics of minerals. Some of these  include solid, inorganic, naturally occurring, definite chemical  composition, and definite crystalline st â¦ ructure. 2. Second, minerals are inorganic and solid   3. Third, Ever â¦ y mineral is an element or compound with a definite  chemical composition   4. Fourth, minerals are crystalline solids.
