GEOG 106 Chapter Notes - Chapter 12: Anaerobic Digestion, Kerogen, Peak Oil
Document Summary
Aerobic decomposition: air, bacteria & other organisms that use oxygen breakdown plant & animal remains into simpler carbon molecules. Anaerobic environment: one that has little or no oxygen. Kerogen: oil precursor formed by organic matter that accumulates at the bottoms of water bodies. Developed nations consume more energy than developing nations. Developing devote more energy to subsistence activities (agriculture, food production, home heating) Net energy: difference between energy returned and energy invested to achieve it. Coal: organic matter (generally woody plant material) that was compressed under very high pressure to form a dense carbon- rich solid material. Strip- mining: heavy machinery removes earth in long horizontal strips to expose layers to extra coal. Natural gas: consists of methane (ch4) and other volatile hydrocarbons. Oil, crude oil, petroleum (oil + natural gas formed within a wind of temperature, pressure conditions found 1. 5- 3km below surface. Found by creating powerful vibrations or wave patterns.
