Rocks and Minerals pt.1 Flashcards
non-silicates
minerals that don’t contain silicon +oxygen bonded together
ores
natural rock or sentiment that contains valuable minerals or metals
specific gravity
the ratio of the weight of the mineral to water
fracture
minerals that don’t break evenly
cleavage
tendency to break along distinct planes/area
ferromagnesian
always contain either iron, magnesium, or both
non-ferromagnesian
do not contain iron or magnesium
polymorphous
minerals that contain the same elements and ratio, but atoms arranged differently
extraction
take out ores + minerals
luster
the way a mineral reflects light
silicates
minerals that contain BOTH oxygen +silicon bonded together
reclamation
return land to it’s condition before mining was done
crystal form
external shape
hardness
resistance to scratching
streak
color of a mineral in its powered form
color
the hue it gives off
silicates tetrahedron
an ion with 4 oxygen atoms joined to one silicon atom
what is the difference between graphite and diamond
diamond has a tightly packed, three-dimensional network of carbon atoms, making it extremely hard, while graphite has layered sheets of carbon atoms that can slide over each other, resulting in a soft, slippery texture
