Answer 1

Short Answer:1. The five defining characteristics that all minerals have in common are: naturally occurring, inorganic, solid, definite chemical composition, and ordered internal structure.2. Minerals are formed in two main ways: by the cooling and solidification of molten rock (igneous process) or by the alteration of existing minerals due to heat and pressure (metamorphic process).3. An ore is a mineral or rock that contains sufficient minerals with important elements including metals. Its classification may change over time due to changes in market demand, technological advancements, or changes in the availability of resources.4. A gem is distinguished from other minerals by its beauty, rarity, and durability, which makes it suitable for use in jewelry.Multiple Choice:5. a. silicates6. c. color7. a. oxide8. d. fracture9. b. density10. a. color11. a. native element
