Elements they contain
How do we identify minerals?
Color of Powdered form
how easy the rock scratches materials
Color (can be misleading)
Random pieces (breaks)
Other Properties used for describing physical properties of minerals
Density, Smell, ETC.
Mohs Hardness Scale?
1-10 scale of hardness

What determines minerals properties?
Rocks and Minerals related?
Rocks are composed of minerals
3 types of rocks
Igneous, Sedimentary, and Metamorphic
Igneous rocks form?
Intrusive Igneous Rock?
comes from under the earth
Extrusive Igneous Rock?
comes from above the earths surface
Igneous Rock with glassy appearance?
Igneous rock that has larger crystal grains?
This process affects the rate of crystal growth within a rock...
rate of cooling
How Metamorphic rock is formed?
Heat and Pressure
How metamorphic rocks are classified with layers
How metamorphic rocks are classified without layers
How sedimentary rocks are formed?
weathering and erosion
small pieces of broken down rock
Pressure (pushing together)
type of sedimentary rock, made of fragments of rock cemented together with calcite or quartz
minerals crystallize out of solution to become rock
Remains of plants and animals
The type of rocks that can form sedimentary
Igneous, Metamorphic, and Sedimentary (All Rocks)
