Lava vs magma |
Lava: molten rock on surface that has lost most gas, like flat soda Magma: molten rock below surface and surrounded by rock, retains most gas, like unopened soda |

3 ways to form sedimentary rocks |
1) compaction 2) cementation 3) precipitation |
|
|
Definition of sediments |
Can be made of rocks, organic debris, minerals, plastics, glass, etc. And are lithified to form sedimentary rocks |
|
|
Mineral ID techniques |
1) color 2) streak 3) luster 4) hardness 5) fracture 6) cleavage |
|
|
Mineral ID smoking guns |
1) magnetism 2) hydrochloric acid 3) smell 4) taste |
|
|
Sedimentary ripple mark |
Formed from wind or water on loose sediments 1) symmetrical 2) asymmetrical |
|
|
Sedimentary mud cracks |
Water evaporates drying up the sediments leaving cracks |
|
|
Definition of metamorphism |
Change in mineral content and or structure due to directed pressure, heat or contact with hydrothermal fluid |
|
|
Agents of metamorphism |
1) temperature - lower 400°F -Upper depends on mineralogy 2) pressure -lithostatic: equal - directed |
|
|
Parent rock |
Preexisting rock that goes through metamorphism |
|
|
Foliation |
Layers perpendicular to the directed pressure |
|
|
Types of metamorphism |
1) contact 2)regional 3) dynamothermal 4) hydrothermal 5) shock 6) pyrometamorphism 7) fault zone |
