There are two categories of resources. Name the two

types, give their definition and list 2 examples of each.

1. Renewable resources- can be replenished over a short period of time (ex. Food, plants, animals)

2. Non-renewable resources- takes millions of years to replenish (ex. Fossil fuels- coal, oil, natural gas)

What are fossil fuels? List three examples.

• Fuels that come from remains of organisms that lived long ago (coal, oil-petroleum, natural gas)

What does coal form from? Give the 4 stages of development for

coal.• Decomposed plant and animal material

that has been buried and undergone extreme heat and pressure over millions of years– Peat– Lignite– Bituminous coal– Anthracite

Define Ore

• A useful metallic mineral that can be mined at a profit

Why are non-metallic resources extracted and processed?

• Extracted and processed for the nonmetallic elements they contain or for their physical and chemical products (used for building materials and industrial minerals)

List two reasons why a person may choose solar energy over

another type of alternate energy.

• Fuel is “free” and it is non-polluting

List two reasons why a person may not choose solar energy over another type of alternate

energy.

• Equipment is expensive and can not be used at night

Explain nuclear fission.

• Process in which uranium nucleus splits in two releasing heat energy

Nuclear energy has its pros and cons too! List them

• Pros– Produces large amounts of energy– Clean

• Cons– Expensive to build nuclear plant– Disposal of waste is dangerous

List the “the good and the bad” about wind energy

• Good– Clean – Can be used at night

• Bad– Causes noise pollution– Need large amounts of land

In the future, wind energy could produce what percentage of the nation’s demand for electricity?

• 5-10%

Hydroelectric power Explain where the power comes from and give the advantages and

disadvantages.• Comes from the force of falling water• Advantages

– Clean– Water is plentiful/renewable

• Disadvantages– Dams must be rebuilt– Not many areas for development

Prefix geo means:

• Earth

How is geothermal energy harnessed? Give an example of

geothermal energy.

• Tapping into natural underground reservoirs of steam and hot water

• Geysers/springs

List the advantages and disadvantages of geothermal

energy.

• Advantages– Produces large amounts of power– Doesn’t harm environment

• Disadvantages– Source eventually runs out

How is tidal power harnessed?

• In and out flow of tides produces power

How do we use fresh water on a daily basis?

• Cook, clean, grow food

How much of Earth’s water is fresh water?

• 3% but only 1% is available for us to drink

Explain the difference in point source pollution and non-point

source pollution. Be able to identify each.

• Point-source= know the source of the pollution

• Non-point source= source of pollution is unknown

What is runoff?

• Water that flows across the land

What helps maintain life on Earth?

• Atmosphere

Why is the ozone important?

• ozone layer protects us from sun’s harmful rays

What are the lands resources?

• Soil, forests, mineral and energy resources

How does mining for resources damage the land?

• Destroys plants and habitats for animals

• Causes soil erosion

Explain conservation. List 2 examples of how we can

conserve resources.• Careful use of resources

Explain pollution prevention and give examples of how to

prevent pollution.• Avoid polluting

When were the first laws passed to decrease water pollution?

• 1970s

Clean Water Act/Safe Drinking Water Act/Clean Air Act

• Clean Water- reduced water pollution

• Safe drinking water- protected our drinking water

• Clean air- reduced the amount of pollution in our air

Resource Conservational and Recovery Act

• Decreased unsafe dumping

Comprehensive Environment Response, Compensation and

Liability Act• Requires the clean up of hazardous waste

sites

Know the 6 pollutants that are known to cause health

problems• Ozone, carbon monoxide, lead, sulfur

dioxide, nitrogen oxides, fine particles

What is compost?

• Decomposed organic matter natural fertilizer

Explain recycling. Be able to identify examples of recycling.

• Reusing items

What is a landfill?

• Area in which waste is dumped has a plastic or clay liner that prevents waste from seeping into ground
