|
Cont-oceanic plate convergence |
Convergent plate boundaries come together creating mountains. During a cont-oceanic convergence, one subducts underneath the other due to volcanic activity. |
|
|
Mining Law allowing U.S. citizens to own natural resources |
1872 mining law |
|
|
Gold-silver-metallic extraction and leading extractions |
A heap-leach extraction procedure where the negatively charged cyanide is leached through an ore pile. Cyanide picks up positive charged ions, drains it, melts it, and dissolves gold while leaving most other minerals behind. |
|
|
Earthquake P-wave |
Primary wave/first and fastest seismic wave First to arrive at seismic station Travels through rocks/fluids Pushes/pulls rocks it moves through |
|
|
Earthquake S-wave |
Secondary wave/2nd seismic wave you feel in an earthquake Moves rock particles up and down or side by side |
|
|
Best geology to build on |
Granite is most stable because it absorbs |
|
|
Worst geology to build on |
Soft mud Sand and gravel Land fill (around bay) is the worst |
|
|
Newport-Inglewood fault |
The oil basins of LA from Inglewood to Newport Beach follow a straight line. The Wilmington oil field stretches across this line. |
|
|
Best/easy metal to recycle |
Aluminum |
|
|
Most costly aspects of flooding |
Government encourages flood victims to rebuild/resettle on flood plains. Mold forms underneath and creates costly expenses because of contamination (carpet, drywall, etc) |
|
|
Last big SF earthquake |

|
|
San Andreas fault |
Pacific plate including western CA and the pacific ocean moving northwest. North America plate central/eastern CA Moves west Side by side motion |
|
|
Damage to hospital |
1971 San Fernando earthquake Rigid Lots of concrete Elevator/stairway broke off building Top of building shifted while 1st floor was fixed |
|
|
Compressional force |
Pushes together Shortens continent |
|
|
Tensional force |
Pulls apart Extends continent Creates basin and ranges |
|
|
Shear stress |
Side by side movement Transform fault |
|
|
Liquefaction |
Soil liquefaction is when shaking causes soil to lose structure (liquidfaction) |
|
|
Mount Rainier |
Active volcano Explodes towards the west side which is facing Seattle/Tacoma Cities/communities are build on mudslide/landslide area |
|
|
San Andreas fault earthquake potential |
Compression zone on/near San Gabriel mountain causing land to continuously rise |
