GEOL 101 The Human Impact on Earth’s Environment I & II I. Recourses and Reserves Resources – the entire amount of material that may be available for use sometime in the future o Types Energy –oil, natural gas Mineral Metallic – iron copper Nonmetallic – sandstone, granite Water o Renewable – resource that can be replenished over a short time spans (months, years, decades) Solar Wind Geothermal o Nonrenewable – resources that are created by processes that take long spans of time to form(thousands of years) Fossil fuels Nuclear energy Quad unit of measure to measure energy o 1015 BTU Reserves – known resources that can be recovered economically and legally today o Will always be smaller than total resource Sources of energy on Earth o Incoming solar radiation o Geothermal energy o Gravitational energy Fossil fuels o Those energy resources that have formed as the result of the burial and subsequent transformation of organic material - Conventional – ones we have been using for a long time Oil Natural gas Coal Non – conventional Shale oil Oil shales Tar sands Gas hydrates II. Coal Process of making coal o Production of large amounts of biomass o Preservation in an oxygenpoor environment - EX; peat o Burial and compaction Thermal condition of Oil – temperature and duration - Oil – wet gas – dry gas – gone Effect of burning coal - Release of carbon dioxide - Release of sulfur that contributes to acid rain - Strip (surface) miming III. Oil and gas Form oil and gas o Production of large amounts of biomass o Preservation in a reducing (oxygen –poor) environment o Burial increases heat and pressure, causing maturation (breaking down of organic matter into liquid or gas) in a source rock - What happens after formation? Migration out of the source rock into a porous and permeable reservoir rock Tapping of fluids by an impermeable deal Shale gas – natural gas trapped within shale - Increasingly important source of natural gas in the US over the past decade - Interest has spread to potential gas shales in the rest of the world IV. Alternatives to Fossil Fuels Nuclear energy Advantages Virtually inexhaustible supple Low carbon footprint o No CO 2 Disadvantages Potential for nuclear accidents How to deal with spent nuclear fuel - SC is a nuclear state Less than 50% of our energy comes from nuclear power 3 overall in the states, 1 overall per capita Solar Energy Advantages Virtually inexhaustible supply Disadvantages Very expensive with current technology No as portable as hydrocarbons Geothermal energy Advantages Cheap and clean Disadvantages Cannot be transported long distances Sample Exam Questions Most sediment accumulates __. a. In rivers and streams b. On continental shelves c. At the base of the continental slope d. On the abyssal plain Coal forms from ____. a. Large accumulations of dinosaur bones b. Large accumulation Plant material c. Large accumulation Coral fragments d. Large accumulation Bacterial matter Petroleum and natural gas are considered ____ energy resources. a. Non – renewable b. Renewable c. Geothermal d. Hydrothermal The main component of natural gas in __. a. Nitrous oxide b. Methane c. Carbon dioxide d. Sulfur dioxide Formation of oil and gas occurs within which part of the earth a. Near the surface b. 5 – 10 km depths c. 1020 km depths d. 2030 km depths Oil and gas deposits can be found in ___. a. Anticlines b. Synclines c. Monoclines d. Homoclines
