2
Examples: metals arable land fossil fuels old-growth forests coal oil water power Air Sun crops
3
Advantages: Stays for a long time They are constant Disadvantages: Expensive Can harm wildlife Not reliable Some put off carbon dioxide (biomass) Examples: Sun Wind Water Geothermal energy trees
4
Advantages: We need it to make gasoline Examples: Fossil fuels Natural gas Nuclear energy Disadvantages: Acid rain Pollution
5
Advantages: a chemical energy is changed into heat and light Examples: Coal Oil Natural gas Oil + Natural Gas=Gasoline Coal + Natural Gas= combine to make petroleum Disadvantages: pollutes the atmosphere
6
Advantages: changes a chemical to heat and light Examples: Lignite Bituminous Anthracite Disadvantages: pollutes the atmosphere
7
Advantages: Changes into heat and light Power vehicles Power stoves, ovens, fireplaces Examples: Lamp oil Gasoline Diesel fuel Crude oil Disadvantages: Develops over long periods of time Air pollution Water pollution
8
Advantages: Renewable Does not cause hazardous/toxic pollution Examples: Solar panels Flat mirrors Disadvantages: We do not have the technology to harness all of its energy Cover large areas with solar panels Noise pollution Doesn’t work at night or on overcast days
9
Advantages: Renewable Nonpolluting (air, land) Not harmful to the environment Does not produce waste Inexpensive Examples: Windmills wind farms Disadvantages: Few regions have winds strong enough to generate electricity on a large scale Noise pollution Depends on the weather
10
Advantages: does not cause pollution and it is renewable *Environmental Friendly Examples: Niagara Falls Water falls Dams Doesn’t use “fuel like” oil Disadvantages: Reservoirs behind the dam can fill up with sediment Increased erosion Dams are expensive
11
Advantages: Iceland and California use hot water and steam from geysers to heat their homes. Examples: Geysers Hot springs Disadvantages: Sometimes not found, close to Earth’s surface **Found below the earth’s surface Can release hot, salty water at Earth’s surface
12
Advantages: only makes up 8 % of the total energy used in the U.S. Power entire cities Examples: power plants uranium nuclear weapons Disadvantages: makes its use limited Radioactive wastes Nuclear accidents
13
Advantages: part of water cycle, so it is renewable *free to harvest Example: Used in industries and on farms Disadvantages: it takes a long time for it to move through rock layers *huge effort to harvest *if not much rain an area will not have much of a resource (crops need rain)
14
Advantages: take in carbon and stores it *Purifies the air Examples: Yellowstone Yosemite Amazon Regulates the water cycle Disadvantages: no forests = more carbon in the atmosphere (might cause global warming)
15
Advantages: Sometimes large deposits of valuable minerals are found in one place Can be mined for profit Example: hematite makes motorcycle parts and saw blades, diamonds, gold, etc. Salt Copper Iron Disadvantages: Costs a lot to get the minerals out of the rocks Air pollution Water pollution
16
Definition: any nonliving part of the environment Examples: Air current Temperature Moisture- water Light Soil
17
Definition: any living or once living organism in the environment Examples: Animals Plants Insects Humans
