What processes drive the movement of water in the hydrosphere of the earth?

convection and conduction

what are the power units??

Watt and Horsepower

First Law of Thermodynamics

energy can neither be created nor destoryed only transfered or transformed (photosythsis)

Second Law of Thermodynamics

a significan fraction of evergy is lost as heat, when it moves from one medium to another

steamm to turbine, what energies aare being used?

kinetic to mechanical

Hwo does a generator work in an electicity producing powerplant?

the generator consists of copper wire coils and magnets, one is stationary (stator) and the other rotates (rotor). as the turbine spins, it causses the mmagnnets in the generatorr to passs oover the wire coils (or vice versa), generating a flow of electrons through the copper wire, and thus producing an alternating current that passes into electrical transmission lines

What are the three main sources for the global production of electricity?

fossil fuels 64%
Nuclear 17%
renewable energy sources 19%

What fuels provide the world's energy?

fossil fuels- 80%

oil 35%
natural gas

where is coal found

underground in seams, where there used to be large deposits of plant matter

WHat does the amoint of resource that can be extracted depend on?

The technology available and the cost of extraction

what is a proven reserve

an estimate of how much fuel can be obtained from an exploratory well

what is utilized to extract oil after the easy stuff is extracted?

pressure extraction

Describe the impacts of drillling for oil on the ennvironment.

moderately damaging because little land is needed, however during trnasport is when the worst damages can occur

Worst envi oill disasted in the UU.S

Deep Water Hrizon Drilling Rig

rank (least to best) the different types of coal and desscribe aa bit

peat lignite (brown coal) subbituminous bittuminous (black coal) anthracite (black coal)

What is the cost of mining and remving coal frrom the eart?

it leaves hazardous slag heaps containing sulfur that can be leeched out and enter the water table

How can the by-producs of coal be removed?

through the actions of scrubbers which contain alkaline substances that percipitate out much of the sulfur dioxide


burning coal with limestone

What aare two wastes produced by coal?

fly ash and boiler residue

What is natural gas used for?

home heating and cooking, but can be burned to generate electricity.

T/F Some powerplannts are designed to switch between oil and natural gas fuelss, deependingg on the cost


T/F The engines of Car can be modified to burn Natural Gass


By products of natural gas

only produces CO2 and water no NoX or SO2 associated with coal and oil (because it has a simple molecular structure)



How llong willl oil last? natural gas? coal?

nuclear accidents

Chernobyl and Three Mile Isle

Name 2 Saftey issued of nuclear reactorss and describe them

1. Redioactive elements: Gamma rays produced by radioactive decay can damage cells and DNA, which can cause lukemia and thyroid cancer

2. Concern's for one's saftey: people suffer from stress by concerns for their saftey resulting in NIMBY

what percentage of oour energy needs are ccurrently met using renewable sources?


What is the llargest used rrenewable resourcee used today?

biomass (wood, Charcoal, poop)

what is an ineffficient way to use biomass?

the use of gasohol (90% gas 10% ethanol)

becuase it is produced by fermenting agricultural wastes which is energy intensive
plus is releases CO2


1. produces no air pollution but does produce thermal pollution

WHat's the double ended sword of dams?

1. it changes the rate at which the river flows
2. leads to the destruction of habitats


1. as water is held behind, new habitats, in the form of wetlands are created

Describe silting

an issue with dams in which as water sits behind a dam, the normal sediments the river carries gets trapped behind the dam and settle to its bottom, therefore, the sediment that was used to fertilize the flood plains around the river is not passed farther down the river

What is 3 issues that occur with dams

1. silting
2. the reservoir behind it has a greater serface area therefore a higher rate of evaporation and water loss then before
3. fish that spwan normally in the river's water no longer have a place to do so.

What are fish ladders?

things dams use to let fish return upriver through a dam to spawn

Why is the development of hydropower as an alternative fuel source limited

because there is a limited number of rivers of sufficient power in the world that can be used for these purposes

What do solar panels do?

absorb solar eneryg and pass the energy on to tubes in which water is circulating

What is direct collection of solar energy? describe

Photovoltaic cells, which produces elecrticity that is stored in a battery.

works by electrons are energized and can flow freely, producing an electrical current

regional electric grid


(if not connected) stored in abtteries for llater use )

When was wind energy first used?

17th century

What is the base of a windmill called?


What are the crack that geothermal heat escapes frrom called?

geysers, hydrothermal vents or hot springs

How does goethermal heat produce electricity??

by using the naturally heated water, and converting it into steam

Where is Geothermmal heat most heavily used?


Why is Geothermal heat a limited source of energy?

Because if the ground water is used faster then it can be replaced then is source is limited and only a few areas have geothermal sources to tap into

What are some cons of geothermal heat?

1. salts that are dissolved in the water corrode machinery parts
2. some gases that are trapped in the water may be releeased when the water is utilized

How can ocean tides be used for energy?

dams must be errected to harness the energy of the tides

or a protocol desgin called LIMPET ( land installed marine powered energy transformer) may be used (Scotland)

Describe how energy would be harvested throuugh hydrogen cells.

through a process of electrolysis to release the Hyrdrogen from water and then producing the electricity through a process of reverse electrolysis

energy conservation

reducing our use of fossil fuels and practicing sustainability (less impact we have on producing energy)

Fuels that can be used in cars that you didnt know from before. pollution?

natural gas

CO2 and water vapor

What happens when a car is retorfitted with a natural gas fuel tank?

can use wither gasoline or methane fuel

energy input is

always equal to energy output

What is the ratio of nonrenewable sources to renewable sources in developed countries today?

80% : 20%

what can uranium be used for?

nuclear weapons and to generate electricity (fission)

arrange the following energy sources in order in relation to their deisovery and use by human kind

animal powerr
nuclear power
wind and water power
