Transcript Natural Resorces

NONRENEWABLE
AND
RENEWABLE
RESOURCES
Earth’s Resources
• Mankind and Its’ societies have
become increasingly dependent on
Energy resources for the:
– production of manufactured goods
– raising of agricultural product
– mining, drilling and mineral exploration
– distribution of these products
– transportation
– services provided by utility companies
HMMMM....
What do you think
nonrenewable
resources are?
Break it down...
Nonrenewable?
Resource?
NONRENEWABLE RESOURCES
A nonrenewable resource is…
a natural resource that cannot be remade or re-grown at a scale
comparable to its consumption.
COAL, PETROLEUM, AND GAS
Coal, petroleum, and
natural gas are
considered
nonrenewable because
they can not be
replenished in a short
period of time. These
are called fossil fuels.
It takes fossil fuels 300 million yeares to form
• Dino’s first appeared during the Triassic
period, approximately 230 million years
ago, and for 135 million years, from the
beginning of the Jurassic (about
200 million years ago) until the end of
the Cretaceous (65.5 million years ago)
• Therefore fossil Fuels “DID NOT” form
from DINOSAURS
HOW IS COAL MADE ???
HOW ARE OIL AND GAS MADE ???
WHAT WAS THE DIFFERENCE
BETWEEN COAL AND OIL/GAS?
States of Matter
• Solid – Coal
• Liquid – Oil –
• World’s #1 fossil Petrolium
fuel source
• “Black Gold”
• Swampy plants • Marine plants &
animals
• Gas – Natural
gas
• Marine plants
and animals
• Mining
– Coal
• Drilling
– Oil
– Natural gas
Reserves
• Amounts that can be extracted from
the Earth in a profitable manner.
• Fuels can not be considered
“Reserves” unless they can be
extracted Economically.
NUCLEAR ENERGY
Nuclear fission uses
uranium to create
energy.
Nuclear energy is a
nonrenewable resource
because once the
uranium is used, it is
gone!
Nuclear Reactions
•Fission: fizz apart
•Splitting of an Atom
•Reactors and bombs
•Fusion: fuse together
•Combine two atoms
•Star Power(SUN)
Problems with Nuclear Production
• Radio Active Waste Products
• Human Safety
• Non-Renwable
HMMMM....
If nonrenewable
resources are resources
that cannot be re-made
at a scale comparable
to its consumption,
what are renewable
resources?
RENEWABLE RESOURCES
Renewable resources are
natural resources that can be
replenished in a short period
of time.
● Solar ● Geothermal
● Wind ● Biomass
● Water
SOLAR
•Energy from the
sun.
•Solar Panels,
batteries, voltage
invertors
•Why is energy from
the sun renewable?
GEOTHERMAL
•Energy from
Earth’s heat.
•Drilling and
piping of steam
•Why is energy
from the heat of the
Earth renewable?
WIND
•Energy from
the wind.
•Wind mills
and turbines
•Why is energy
from the wind
renewable?
BIOMASS
•Energy from
burning organic
or living matter.
•Corn and sugar
cane
•Why is energy
from biomass
renewable?
WATER or HYDROELECTRIC
Energy from the
flow of water.
Potential and
Kinetic energies
Why is energy of
flowing water
renewable?
Fontanna Dam N.C. Mountians G.S.M.N.P.
Shuckstack Fire Tower from Fontanna
Dam
Wave, Ocean Currents and Tide Action
Twin underwater turbines should be generating 1.2 megawatts
of electricity, a demonstration of tidal power technology.
Wave Action – Bobbing
A giant buoy that generates
electricity
by bobbing up and down in the
ocean’s waves
Ores
• An ore is a type of rock that contains
minerals with important elements
including metals. The ores are
extracted through mining; removing
metals from ores is smelting
• Must be Profitable
• Bauxite Ore - Aluminum
Reclaimation of the Land
• to make the land where a location of
resource extraction, such as, a mine,
a strip mine or a drilling operation
has been left environmentally
suitable for future use.
Stewardship
• A concept of sustainable development,
using state-of-the-art mining and extraction
techniques that produce essential natural
resources while preserving the
environment. The development plans take
into account the surrounding landscape
and communities so that the community
benefits from the project environmentally
for the future.
