Rocks and Minerals

General Science

What is a mineral? naturally occuring, inorganic (not living) solids that have a definite chemical composition and crystal structure
naturally occuring can't be man-made; made by nature
inorganic not living - not formed from living things or their remains
solid has definite shape and volume
definite chemical composition either a single substance or combination of elements
crystal structure atoms arranged in a definite pattern - repeated over and over (like patches on a soccer ball
8 ways to identify minerals color; luster; hardness; streak; density; crystal shape; cleavage; fracture
hardness ability of mineral to resist being scratched
streak color of a mineral in powder form (more reliable than color)
density the amount of matter in a given amount of space
cleavage tendancy to split along flat surfaces
fracture tendancy of a mineral to break with rough or jagged surfaces (like a fractured bone)
luster way a mineral reflects light (metallic or nonmetallic)
special mineral properties taste; smell; reaction to hydrochloric acid; reaction to UV light;
Moh's Hardness Scale characterizes the scratch resistance1=anything harder can scratch it; 10=nothing can scratch it
1 talc
2 gypsum
3 calcite
4 fluorite
5 apatite
6 feldspar
7 quartz
8 topaz
9 corundum
10 diamond
1. How minerals form 1. cooling magma (lava)
fast cooling magma small crystals
slow cooling magma very large crystals
2. How minerals form 2 elements dissolved in a liquid-liquid evaporates, elements stay behind and may form minerals
rock one or more mineral
igneous rock (ignite) when molten lava cools and hardens
sedimentary (sediments) formed from particles that have been carried along and deposited (dropped) by rivers/streams/wind
metamorphic (mighty morphin power rangers) formed when chemical reactions change existing rock into new knds of rocks; pressure, heat and water can all melt and change rock
The Rock Cycle continuous chaning of rocks from one kind to another over long periods of time
Uplift all things are pushed up to the surface of the earth by natural earth processes (earthquakes, volcanoes,...)
