geomorph midterm
earth's changing surface
| Term | Definition |
|---|---|
| geomorphology | the investigation of landforms, processes, and implications for people and the environment |
| geosciences foundation | -interlinked with colonization and oppressive systems -validated intense racism |
| landscape evolution | -climate -biology -tectonics -geology -topography |
| uniformitarianism | -geologic processes that occurred in the past can be explained by current geologic processes -present = key to the past -processes that have shaped the Earth in the past are essentially the same as those operating today -day to day |
| catastrophism | -geologic processes occur suddenly -episodic |
| geographic cycle / cycle of erosion | -evolution of landforms stating a progressive cycle of erosion, stages are sequential and non-reversible and is driven by climate -young ->mature -> old -> peneplain |
| general systems theory | -how different parts of a system interact and influence each other -A system as a set of objects which are related to one another and operate together as a complex entity -analysis focuses on the relationships between objects or characteristics. |
| morphological system | -relationships btwn elements & attributes in vague sense, only on measured features/correlations -understand form/morphology of a feature as system based on connections btwn elements -don't understand exactly how processes work to transfer energy/matter |
| cascading system | -flow of energy/matter from one element to another and understand processes causing mvmt -don't fully understand quantitative relationships that exist between elements related to the transfer of energy and/or matter. |
| process-response system | -integrates characteristics of morphological & cascading systems -model the processes involved in the mvmt, storage, & transformation of energy / matter btwn system elements -understand the form of system in terms of measured features and correlations |
| control system | -a system that can be intelligently manipulated by the action of humans |
| earth as a system | |
| exogenic processes | |
| endogenic processes | |
| 5 principles of process geomorphology | |
| equilibrium | |
| energy, force, resistance | |
