Document Summary
America during one of the ice ages o the last ice age ended rapidly at 11 ka, yielding the present interglacial period (the holocene epoch: the cenozoic era: age of mammals: o recovery after k t impact led to new species o dinosaurs extinct, but early bird descendants radiated o grasses newly appeared, rapidly expanded o rapid diversification of mammals. H c bonds are created via photosynthesis by reaction of water and co2 to form sugar and oxygen o 6co2 + 12 h2o + light c6h12o6 + 6h2o +6o2: biomass (oceanic and terrestrial) o buried plants, algae and other organic remains can progressively be converted to fuels. These fuels, which include oil, gas, and coal, are called fossil fuels to emphasize that they come from ancient organisms preserved in the rock for geologic time: energy involving gravity o tidal energy.
