what are the two most abundant elements that make up earths crust
silicon,oxygen
what does inorganic mean
materials are not living
what does the arrangement of an atom and the bonds between them reflect about a mineral
how it breaks, how hard it is, and what crystal shape it has
what are all of the ways to identify a mineral
luster,hardness,streak,cleavage,atomic arrangement,crystal shape

metallic nonmetallic
how does metallic luster reflect light
like a metal surface
how does nonmetallic luster reflect light
has a waxy or earthy appearance
how do you preform a streak test
rub the mineral on an unglazed porcelain tile
what are the two types of breakage that can happen
cleavage and fracture
