Study Notes
Earth's Resources
- Earth's resources are categorized as renewable and nonrenewable.
- Renewable resources replenish within short spans of time (months to decades).
- Nonrenewable resources take millions of years to form.
Fossil Fuels
- Fossil fuels are hydrocarbons used as fuel (coal, oil, and natural gas).
Oil Traps
- Anticlines are common oil traps.
- Oil, gas, and water are trapped within layers of rock.
Tar Sands and Oil Shale
- Tar sands and oil shales can become substitutes for dwindling petroleum.
Mineral Deposits
- Important mineral deposits form through igneous processes and hydrothermal solutions.
- Ore is a useful metallic mineral that can be mined profitably.
Mineral-Rich Hot Water
- Mineral-rich hot water seeps into rock fractures.
- Hydrothermal deposits can form in these fractures.
Nonmetallic Mineral Resources
- Nonmetallic mineral resources are extracted for their nonmetallic elements or physical/chemical properties.
Uses of Nonmetallic Minerals
- A table lists various nonmetallic minerals, their uses, and geological occurrences.
Alternate Energy Sources
- Solar energy is free and non-polluting.
- Nuclear fission splits heavy atoms (like uranium-235) when bombarded with neutrons, and releases heat energy.
Wind Energy
- Wind power can meet 5-10% of electricity demand in the next 50-60 years.
Hydroelectric Power
- Hydroelectric power is generated by falling water.
- Stored water behind dams releases energy to produce electricity.
- Strong water flow drives turbines to generate electricity.
Geothermal Energy
- Geothermal energy taps natural underground steam and hot water reservoirs.
- Hot water heats buildings or turns turbines.
Tidal Power
- Tidal power is harnessed by constructing dams across bays or estuaries.
- The strong in-and-out flow of tidal water drives turbines.
Water, Air, and Land Resources
- People use fresh water for daily activities.
- Freshwater pollution has point (specific source) and nonpoint (unspecific) sources.
- Runoff is water flowing over land.
Pollution in the Air
- Increased carbon dioxide alters the carbon cycle and contributes to global warming.
- Air pollutants react to form acids, causing acid rain.
Major Primary Pollutants
- A pie chart shows the percentages of major primary pollutants and their sources.
Land Resources
- Land provides soil, forests, minerals and energy.
- Mining can damage land resources through soil, vegetation and contour damage as well as erosion and pollution.
- Surface mining significantly impacts Earth's surface.
Protecting Resources
- Conservation involves careful resource use.
- Pollution prevention stops pollutants from entering the environment.
- Laws like the Clean Water Act and Safe Drinking Water Act were established to protect and improve water quality.
Saving Energy
- Ways to save energy include recycling, using solar energy, energy-efficient light bulbs, and turning off appliances.
Caring for Land Resources
- Protecting land resources includes preventing pollution and managing resources wisely.
- Composting and recycling are methods of managing resources wisely. Note: The provided OCR contains some unclear/partial data, so this summarized info is based on the provided text.
