chapter 26 Flashcards
Minerals
a naturally occurring inorganic solid with a crystalline form
streak
the color of a mineral in powder form
fracture
minerals that break with an irregular surfaces exhibit
hardness
minerals ability to resist scratching
magma
Molten rock mineral inside earth
cleavage
when a mineral breaks along preferred plane of weakness creating sets of smooth parallel sides
a mineral is
a naturally occurring inorganic solid with a Crystalline form
what are two most abundant chemicals that make up earths crust
oxygen and silicon
what does inorganic mean
material that is not living
what does the arrangement of an atom and the bond between then reflect on the mineral
break hardness and what shape it has
what are all the ways to identify a mineral
streak, atomic arrangement, cleavage, luster, hardness, fracture, crystal shape
what are the two types of luster
metallic and non metallic
how does metallic luster reflect light
like a metal would reflect light
how does non metallic luster reflect light
very poorly like a glass or very earthy
how do you preform a streak test
you rub the mineral onto another solid object
what are the two types of breakage that can happen to a mineral
fracture and cleavage
whats the naMe Of the scale of HardneSs
Mohs hardness scale
range on Moh’s hardness scale
1 to 10 10 being diamond
how many crystal shape systems are there
There are 6
minerals grow from the
what are the three ways minerals can form
magma, water evaporation, and
what are the two mineral groups
metallic and non metallic
which minerals mineral group is the most abundant in earth
what elements are silicates made of
