Plate Tectonics
Where explosive volcanoes form
Subduction Zones
mineral class built of tetrahedra
Silicates
Texture of intrusive igneous Rock
phneritic
rock type made of calcite
limestone
Age of planet Earth
4.6 billion years
Plate Boundary where new oceanic lithosphere forms
Divergent boundaries
Releases CO2 when acid is applied
Calcite
phaneritic igneous rock which contains quartz, feldspar, and hornblende
granite
rock type made of rounded clasts bigger than 2mm
conglomerate
layers in the lithosphere
crust and upper mantle
Why volcanoes don't form at Continent to Continental plate collisions
No water for Flux melting
Cleavage angle of ~ 90 degrees, found in granite
Potassium Feldspar
Occurs at divergent plate boundaries
Basalt
ROCK TYPE feels smooth (no grit) when put between your teeth!
SHALE
2 biggest sources of interior heat
radioactive decay and residual heat from accreation
What type of plate boundary is the San Andreas Fault?
Transform
This mineral causes acid mine drainage and acid rock drainage
pyrite
Erupted in great quantities at Mt Pinatubo
volcanic ash
process which chemically weathers mafic minerals
oxidation
rock type found on Earth's ocean floors and the moon
Basalt
causes melting at divergent plate boundaries
thiningg of lithosphere, decompression melting
is the first mineral to crystallize in Bowens reaction Series
Olivine
texture indicating 2 stage cooling history
porphrytic
type of sandstone composed of 25 % or more feldspar
arkose
observation that is explained by the doppler ffect
red shift
