tectonic plate movement
this type of plate boundary results in mountain formation.
convergent
the outer most chemical layer of the earth, where humans live.
crust
the heat transfer source that drvies tectonic plate movements via frictional coupling
convection currents
this mining method performed near a water body involves separating valuable minerals from gravel or sand
placer
this act regulates the release of hazardous substances from mining and other practices into the environment (abbreviate_
"strike slip fault" is another name for this kind of tectonic plate boundary.
transform
this physical layer's magma causes movement of the tectonic plates
asthenosphere
this form of heat transfer intraplate - meaning fully inside of a single tectonic plate. It can also cause volcanic activity.
mantle plumes
this method of extracting minerals beneath the surface is often used for coal mining
subsurface
this act requires land used for mining to be restored to the same or better condition when mining is finished (abbreviate)
SMCRA
divergent plate boundaries result in the formation of these in the ocean.
mid-ocean ridges
chemical organization of the earth's interior is determined by this physical property
density
at this type of plate boundary, magma seeps into the ocean.
divergent
dust particles created by explosions for this mining method are very damaging to the environment
mountaintop removal
SMCRA specifically limits environmental damage caused by the mining of this substance
Coal
at an ocean-continental subduction zone, which plate subducts?
ocean
this physical layer exists in a plastic soild state
mesosphere
this area that encircles the pacific ocean has loads of seismic and volcanic activity
ring of fire
the bingham canyon mine in Utah is the largest of these mines, being 4 kilometers wide.
Open pit
this act protects habitats for particularly vulnerable species from being damaged by mining and other practices (don't abbreviate)
Endangered Species Act
the release of solutes at ocean-continental subduction zones by the ocean plate reduces this physical property of the mantle
earth's magnetic field allows us to determine the composition of this layer
core
approximately this percent of heat transfer results in tectonic plate movement (include % in answer)
90%
this is the main acid causing acid mine drainage - a result of subsurface mining (include the word acid in answer)
sulfuric acid
These acts ensure that water is safe and not altered by pollution from mining or other sources. (list acts abbreivated in alphabetical order, separated by a comma and space)
