Minerals – Naturally formed solid that has a repeating three-dimensional shape Minerals are Nonliving material Have crystals Formed in nature solid
Luster Color Streak Cleavage and Fracture Density Hardness
Which property means the way the light bounces off the mineral?
What words can be used to describe a mineral’s luster? Glassy, dull, shiny, greasy
Why is color not a good property to use to identify a mineral? Many minerals have the same color. slate limestone
Streak is simply the color of a mineral powder.
What are three testers that can be used to determine a mineral’s hardness? fingernail, penny, nail
What rock will scratch Calcite but not scratch Orthoclase?
Hardness of some other items: 2.5Fingernail 2.5–3Gold, Silver 3Copper penny 4-4.5Platinum 4-5Iron 5.5Knife blade 6-7Glass 6.5Iron pyrite 7+Hardened steel file

Minerals combine to form rocks There are three types of rocks Igneous Sedimentary Metamorphic
Igneous forms when hot, liquid rock, or magma, cools and hardens Igneous rock formed on the surface is called extrusive Rock formed under surface is intrusive
Sedimentary rocks are formed from compaction and sedimentation Sedimentary contain layers called strata
Metamorphic rock is formed by heat and pressure
