eggs mini test 3(geology, minerals, & mining)

Published by admin on

geology
study of earths physical features, processes, and history
why study geology?
-controls distribution of mineral resources
-controls location of many geological hazards
earths internal layering
-CRUST:thin outer layer rose to top

-fairly dense rock stayed in the middle:MANTLE

-heavy metals sank to the CORE(iron and nickel)

true
layers were formed when earth was molten
core
outer=liquid
inner=solid
crust
continental=less dense/thick
oceanic=more dense/thin
tectonic plates
-not the same as the crust
-based on how materials behave
lithosphere
plates=stiff and cool
aesthenosphere
below=mushy and hot
plate tectonics
-divergent(plates move apart)
-convergent(plates move toward each other)
-transform(plates slide past each other)
plate tectonics
-volcanos and earthquakes
-mineral deposits
-oil and natural gas
-climate
true
rocks and mineral resources are used ALL OVER our homes and businesses
true
if it doesn’t grow it came from a mine
mineral resource
concentration of naturally occurring mineral in or on the earths crust in a form that can be extracted economically
non metallic mineral resources used for:
-agriculture and industry
-construction
-ceramica/abrasives
