Geography of Natural Resources

Resource: naturally occurring material useful to society Gold Ore

Renewable Resources: Resources that be regenerated more quickly than they are being used

Renewable Resources Soil Plants Animals Water Sun Wind

Nonrenewable Resources: Resources that exist in finite amounts and can be used up Natural Gas

Nonrenewable Resources Fossil fuels Nuclear fuels Metals Other minerals (gems, special stones)

Nonrenewable Energy Resources Petroleum Natural Gas Coal Oil Shale Oil Sands Nuclear Energy

Sources of Energy in the U.S.: 1775-2011

Major Sources of Energy in the U.S. Early 1800s: wood Late 1800s through early 1900s: coal Today: petroleum

Crude Oil: Nigeria

Crude Oil: North Sea

Crude Oil Movement

Regional Shares of Proved Oil Reserves

Oil Production and Consumption

Leading Major Oil Producers Saudi Arabia Russia U.S.

Leading Oil Consumers United States China Japan

Major Coal Basins

Largest Coal Producers China United States India Australia South Africa

Dependence on Coal for Electricity in 2011

Coal Development

Coal Ranks: from softest to hardest 1. Peat 2. Lignite 3. Bituminous 4. Anthracite

Coal Grades Low sulfur: less polluting, found in the Rocky Mountains High sulfur: more polluting, found in the Appalachians, not allowed in certain urban areas

Natural Gas Movement

Proved Natural Gas Reserves

U.S. Natural Gas Pipelines

Natural Gas Location associated with petroleum The cleanest fossil fuel Difficult to transport

Synthetic Fuels Oil Shale: enormous potential for energy production, profits depend on the proximity to the surface Oil Sands: expensive to mine, investors commonly lose money in extraction process

Oil Shale Deposits

Oil Shale in Australia

Oil Shale in Australia

Oil Sand Deposits

Mining Oil Sands

Leading Producers of Nuclear Energy

Nuclear Power Plants in the U.S.

World Nuclear Power Plants

Nuclear Power: Milwaukee, Wisconsin

Nuclear Power: Three Mile Island

Chernobyl, Ukraine

Radiation Model After Chernobyl

Renewable Energy Resources Wood Waste Hydroelectricity Solar Energy Geothermal Energy Wind

Wood: its continued use is leading to the depletion of forest resources

Wood for cooking in Malawi and Guatemala Malawi Guatemala

Waste: Anaerobic digester used to create methane

Waste: fermented to create methane

Hydroelectric Power: falling water powers generators to produce electricity

Hydroelectric Power

China: Three Gorges Dam

Three Gorges Dam

Solar Energy: Mainly possible in sunny climates. It is pollution free, but it is difficult to harness.

Solar Energy Photovoltaic System

Solar Energy Parabolic Trough

Geothermal Energy: steam produced when water contacts heated rocks in the earth s crust

Geothermal Energy

Geothermal Energy California

Geothermal Energy: New Zealand

Geothermal Energy: Iceland

Wind Power: wind turbines drive generators to produce electricity

Wind power in California and Alberta California Alberta, Canada

Metals: The U.S. is becoming more dependent on other countries for is metals

Depletion of Metal Resources

U.S. Metals Imports

U.S. Copper Ore Concentration

Copper Mining: Bingham Canyon, Utah

Naturally Fertile Soils

Fertile Soils Grassland soils have more nutrients since rainfall is low. Nutrients are not leached from the soil quickly. Alluvial soils that have been formed by river water are continually replenished with nutrients

Grassland Soils: Mollisols in the U.S.

Profiles of Grassland Soils

Alluvium: Nile River, Egypt

Floodplains: Alluvium being deposited
