chapter 26 Flashcards
a mineral is
naturally occurring,inorganic solid, with a crystalline form
what are the two most abundant elements that make up earth’s crust
oxygen and silicon
what does inorganic mean
non living materials
What does the arrangement of an atom and the bonds between them reflect about a mineral
how the mineral breaks, how hard it is, an what crystal shape it has
mineral
a solid inorganic substance of natural occurrence
streak
a long, thin line or mark of a different substance or color from its surroundings
cleavage
a sharp division
fracture
the cracking or breaking of a hard object
hardness
the quality or condition of being hard.
magma
hot fluid or semi-fluid material below or within the earth’s crust
What are all of the ways to identify minerals
luster, streak, cleavage, fracture, hardness, and crystal shape
What are the two types of luster
metal and non-metillac
How does metallic luster reflect light
very easily, like a metal surface…
How does nonmetallic luster reflect light
glassy appearance
How do you perform a streak test
by rubbing a mineral on a unglazed, porcelain tile
What are the two types of breakage that can happen to minerals
cleavage and fracture
What is the name of the scale to measure the hardness of a mineral
mohs
What is the number range on Mohs Scale of Hardness
1-10
How many different crystal shape systems are there
6 shapes
Minerals grow from the
inside out
What are the 3 ways minerals can form
hot water, molten rock, and evaporation
What are the two mineral groups
Silicates and Nonsilicates
Which mineral group is the most abundant in Earth’s crust
silicates
What elements are Silicates made up of
oxygen and silicon
Nonsilicates do not contain what element
silicon
What mineral is used to make glass
quartz
