Term
| Describe the 5 characteristics of minerals |
|
Definition
*Solid - can not be liquid or gas
*Naturally occurring - found in nature, not man-made
*Inorganic - Not alive and never was, non-living
*Fixed composition - has a chemical formula, most are formed fro compounds of two or more elements. Some minerals consist of one element
*Crystal form - a definite structure in which atoms are arranged |
