Chapter 26 Flashcards
molten rock
magma
minerals that break with irregular surfaces
fracture
color of a minerals powdered form
streak
naturally occurring inorganic solid
minerals
a mineral breaks along preferred planes of weakness creating sets of smooth parallel sides
cleavage
what are the two most abundant elements in earths crust
silicon oxygen
what does inorganic mean
not living
what the arrangment of an atom and the bonds between then refect about a minearls
how hard it is the way it breaks what type of crystle shape it is
what are all of the way to identify minerals
hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
what are the two types of luster
metallic and non-metallic
how does metallic luster reflect light
light is highly reflected off the surface
how does non-metallic luster reflect light
absorb more and reflect less light
how do you preform a streak test
rubbing a mineral on an unglazzed porslin tile
what are the two types of breakage
cleavage, fracture
what is the name of the scale that maesures hardness
Mohs Hardness Scale
measure a metrials resistance
hardness
what is the range on Mohs scale
1-10
how many different crystle shapes are there
seven crystal
minerals grow from
salty water solutions Earth’s surface and underground
what are the three ways minerals can form
volcanic gases,magma,oxidation
what are the mineral groups
which mineral group is the most aboundent in earths crust
silicate minerals
what element are silicons made up of
silicon
nonsilicates do not contain what element
silicon-oxygen
