6. 3 Types of Rocks
Sedimentary rocks forms from particles from other rocks, or remains of plants and animals that are compacted and cemented together. Fossils are found in these rocks.
Igneous rocks form when magma or lava cools.
Metamorphic rocks form when a rock is changed by heat and pressure.

7. To identify a mineral: SNIFC it out!
Solid
Cannot be a liquid or a gas
Naturally Occurring
Found in nature, not man-made
Inorganic
Is not alive and never was, non-living (generally not made from Carbon)
Fixed composition
Has a chemical formula, most are formed from compounds of two or more elements, some minerals consist of one element ex. Au
Crystal Form
A definite structure in which atoms are arranged

8. Identifying Minerals Color Streak – color of a mineral’s powder
Luster – way a mineral reflects light
Density – mass per unit volume
Hardness – uses a scratch test
Crystal Systems
Cleavage & Fracture – cleavage splits easily along flat surfaces; fracture breaks in a irregular way
Special Properties – magnetism, fluorescence
