Rocks are made of
minerals
the smallest part of an element that has all the properties of the element
atom
minerals that contain a combination of the elements are
sililcate minerals
what are ways of describing and identifying different minerals
properties
the way a mineral break along flat, smooth edges.
cleavage
a naturally formed, inorganic solid that has a definite crystalline structure
mineral
substance made of two or more elements that have been chemically joined
compound
name three silicate minerals
quarts
feldspar
mica
list seven different properties
color, luster, streak, cleavage, hardness, density, taste, magnetism, fluorescence, chemical reaction
the resistane of a mineral to being scratched
hardness
substance contains the element carbon
organic
give example of a mineral containing only one element
gold, silver, copper, iron
minerals that do not contain a combination of the elements silicon and oxygen form a group called
non-silicate minerals
minerals come in a variety of
colors
the amount of matter in a given space
density
substances that does NOT contain carboin
inorganic
give an example of a mineral containing more then one element
quarts, feldspar, mica
name 3 non silicate minerals
gold
silver
copper
iron
way a mineral reflects light
luster
taste, megnetism, fluorescence, optical properties, radioactivity, chemical reaction
special properties
pure substances that cannot be broken down into simpler substances
elements
two most common elements in the earth's crust
silicon and oxygen
2 major group of minerals and how they differ
silicate and non silicate
silicate contains silicon and oxygen as the other do not.
color of a mineral in powdered form
streak
how do you determine a minerals streak
strike it on a piece of unglazed porcelain
