chapter 26 Flashcards
is naturally occurring inorganic solid with a crystalline form
mineral
the color of a mineral in powered form is called
streak
when a mineral brakes along preferred planes of wakness creating set of smooth parallel sides, it has
cleavage
minerals that break with irregular surfaces exhibit
fracture
the physical property that measures a minerals resistance to scratching is called
hardness
molten rock material inside earth is called
magma
a mineral is
naturally occurring, inorganic solid, with crystalline form
what are two most abundant elements that make up earths crust
silicon and oxygen
what does the arrangement of an atom and the bonds between them reflect a mineral
how a mineral brakes, how hard it is, types of crystal shape it has
what are all of the ways to identity minerals
luster,streak,cleavage, fracture,atomic arrangement, hardness, crystal shape
what are two types of luster
metallic, non metallic
how does metallic luster reflect light
metal surface… very easily
how does nonmetallic luster reflect light
glass appearance waxy
not as reflective
how do you preform a preform a streak test
rub a mineral on a un gazed porcelain
what are two types of breakage that can happen to minerals
cleavage and fracture
