Document Summary
Earth 119- chapter 23: global change in the earth system. Earth system: the global interconnecting web of physical and biological phenomena involving the solid earth, the hydrosphere, and the atmosphere. Global change: the transformations or modifications of both physical and biological components of the earth system through time. Supercontinent cycle: the process of change during which supercontinents develop and later break apart, forming pieces that may merge once again in geologic time to make yet another supercontinent. Sedimentary sequence: a grouping of sedimentary units bounded on top and bottom by regional unconformities. Biogeochemical cycle: the exchange of chemicals between living and nonliving reservoirs in the earth system. Steady-state condition: the proportion of chemical in different reservoirs remain fairly constant even though there is a constant flux (flow) of the chemical among reservoirs. Global climate change: transformations or modifications in earth"s climate over time. Global warming: a rise in the average atmospheric temperature.
