Mineral Resources (2 types)
Metal
Anything classified as a metal
on the periodic table.
1.
Shiny
2.
Conductor of heat and
electricity
3.
Bendable and ductible
Nonmetal
Mineral Resources (2 types)
Metal
Anything classified as a metal
on the periodic table.
Nonmetal
Compounds of metals and
nonmetals, or nonmetals on
periodic table.
1.
Shiny
2.
Conductor of heat and
electricity
SiO2 ~ glass
Bendable and ductible
H2O ~ water
3.
CO2 ~ carbon dioxide
Ores
Deposits of minerals, from which metals and
nonmetals can be profitably removed.
Ores
Deposits of minerals, from which metals and
nonmetals can be profitably removed.
Differentiation
As magma cools, the more
dense metals sink to bottom
of magma, or Earth.

Contact Metamorphism
Hot water spreads throughout
cracks in rock. Water evaporates
and leaves mineral.

Small bands of minerals. Small.

Vein
Mother lode
Small bands of minerals. Small.
Lots of veins in one place.

Ores are deposited in
one of two ways.
Contact Metamorphism
Hot water spreads throughout
cracks in rock. Water evaporates
and leaves mineral.
1.
Settle in curve of a
stream
2.
Settle in “pockets”
in a stream.
Vein
Mother lode
Small bands of minerals. Small.
Lots of veins in one place.
THE ONLY SURE WAY TO CONSERVE MINERALS IS
CONSERVATION (WHICH MEANS TO USE LESS).
1. Recycling is not bad
2. Using other types of resources is not bad.
3. Conservation is best.
Section 11.1 Review
1. What is an ore?
2. Explain how some ores from through the process of
contact metamorphism.
3. What are some uses of the metals gold, silver platinum
and copper?
4. Explain what is meant by renewable and nonrenewable
resources.
Section 11.1 Review
1. What is an ore? Minerals that can be mined profitably.
2. Explain how some ores from through the process of
contact metamorphism.Ot water will move through
cracks in rocks. The water will evaportate, and leave the
minerals behind.
3. What are some uses of the metals gold, silver platinum
and copper? Gold can be used for conductors, Silver
can be used for jewelry, and photographic film, Copper
can be used for wiring and pipes.
4. Explain what is meant by renewable and nonrenewable
resources. Renewable means it can be replaced in one
human lifetime (like a tree), nonrenewable means it
cannot be replaced in a lifetime (oil, coal, gold).
