BrainPop: Rock Cycle
• Write down 5 facts.
Relevancy
• Why Study Minerals, Ores, and
Fossil Fuels?
– Building supplies
– Basic consumer consumption: gas, oil, etc.
– Land worth $
– Jobs: mining, gemology, mineralogy, oil rigs
– Health: minerals necessary for a healthy body
– Toxicology reports of poisons or harmful
minerals in drinking water
Common Earth Resources
• The following resources have importance based
on their properties:
–Minerals
–Ores
–Fossil Fuels
• Minerals:
–Natural, solid materials found on
Earth that are the building blocks of
rocks
–Each has a certain chemical
makeup and set of properties that
determine their use and value.
Some Minerals Under
Black Light
State Mineral Production
• South Carolina
– Cement, stone, cement, sand and gravel, gold.
• North Carolina
– Stone, phosphate rock, sand and gravel, feldspar.
• Georgia
– Clays (kaolin), stone, cement, clays (fuller's earth), sand and
gravel.
• Tennessee
– Stone, zinc, cement, sand and gravel, clays (ball), coal.
• Michigan
– Iron ore, cement, sand and gravel, stone, crude oil,
magnesium compounds.
In addition to providing
fuel, there are nearly
3,000 different products
made from coal, oil, and
gas. They are used to
make virtually all of
our synthetic and
plastic materials, along
with products such as
inks,
crayons, bubble gum,
detergents, deodorants,
eyeglasses, tires, and
a thousand other
things.
Ores mined

COPPER (Cu) 
•Ores:
Minerals that are mined
because they contain
useful metals or
nonmetals.

Ore Example:
Bauxite is an
Aluminum Ore
• Aluminum: Is the most abundant metal element in the
Earth’s crust. Bauxite is the main source of aluminum.
Aluminum is used in the United States in packaging,
transportation, and building. Guinea and Australia have
about one-half of the world’s reserves. Other countries
with major reserves include Brazil, Jamaica, and India.
Ore Example:
Azurite is a
Copper Mineral
•
Copper: Used in electric cables and wires, switches, plumbing,
heating, roofing and building construction, chemical and
pharmaceutical machinery, alloys (brass, bronze, and a new alloy with
3% beryllium that is particularly vibration resistant), alloy castings,
electroplated protective coatings and undercoats for nickel,
chromium, zinc, etc., and cooking utensils. The leading producer is
Chile, followed by the U.S., and Indonesia.
• Fossil Fuels:
–Natural fuels
that come from
the remains of
living things
–Fuels give off energy
when they are burned.

Properties of Earth’s Resources
• Earth’s resources (minerals, ores, and
fossil fuels) have the following properties
that make them important and useful:
BrainPop: Mineral Identification
• Write down 5 facts.
• Physical
properties:
–hardness
–luster (shine)
–color
–texture (the look
and feel)
–the way the
mineral splits:
fracture (jagged)
or cleavage (flat)
–density
• Chemical
properties:
–ability to react
to acid
–ability to burn
