coal!
What type of organism is coal mostly made from
plants
What type of organism is crude oil mostly made from
Whats another term for Natural Gas, what is its chemical formula
Methane
CH4
what is fission
breaking apart atoms
COAL
Pros- easy to build near cities, controllable energy source, cheap and easy to maintain, lots of uses
Cons- imported from unfriendly countries, releases CO2, non-renewable, expensive to recover, and environmental risks.
What time period is most of our coal from
carboniferous period
Which two elements are the main components of crude oil
High temp and Pressure
what are two structures we build to recover natural gas
pipelines and storage tanks
what element is typically used for nuclear power
Uranium 235
CRUDE OIL
pros- easy to build power plants, controllable energy, lots of uses, cheap and easy to maintain power plants
cons- imported from unfreindly countries, releases CO2 and sulfer, non renewable, environmental risks, expensive to recover.
name the order of the types of coal
1. peat
2. lignite
3. bituminous
4. anthracite
source rock- contains the oil
trap rock- prevents the oil from coming up
explain the process of hydraulic fracking
process of using water and sand to break open rock, releasing the Natural Gas trapped inside.
How do we make this element necessary for nuclear power plants? What is this process called?
Enrichment
NATURAL GAS
Pros- easy to build power plants near cities, controllable energy, cheaper than oil, land ess pollution.
Cons- releases CO2, non-renewable, expensive to recover, environmental risks, explosive, pipelines required.
Describe all 4 kinds of coal
peat- light brown, used for gardening, 60% carbon, not quite rock yet, partially decomposed plant matter, visible plant matter.
Lignite- brown rock, immature form of coal, lighter/thicker/more moisture and plant fragments than coal, softer than coal. 75% carbon
Bituminous- black and dull, harder and thinner than lignite, softer and thicker than anthracite, doesn't burn as hot or as long, sedimentary rock. 85% carbon
Anthracite- hard coal, black and shiny, expensive, thinnest and hardest, metamorphic rock, 90% carbon.
What is an oil shale
How does it differ from crude oil
Natural gas can quickly be converted to CO2 if exposed to the atmosphere. explain how we have so much of it in PA
Natural gas is found in the Marcellus Shale under the ground in PA. Oxygen must be ABSENT
What is half-life? How long is uranium's half-life?
the time it takes for 1/2 of the radioactive atoms to become stable
NUCLEAR
pros- limited pollution, efficient, easier to build near cities, long term, lots of energy, controllable, cost per KWH/efficient, lots of jobs
cons- waste, radiation danger, causes cancer, labor/ maintance cost, $$ to build, potential accidents.
explain how coalification turns dead organic matter into coal
explain how oil is formed
algae and plants die and sink to the sea floor and are mixed with other sediments, which then gets burried. Millions of years + heat + high pressure transform the organisms into fossil fuels.
What are the Marcellus and Utica shales, and which layer is closest to the surface?
Marcellus- a giant rock full of dry natural gases
Utica- a giant rock full of condensation and oils.
Marcellus
explain how a nuclear reactor works
-fuel rods insirted into core wich contains water
- rods removed and struck by nuetrons to start fission
- heat from fission heats water creating steam
whats the best non renewable option in your opinion
nuclear power
