noun

The act of coming into view: appearance. See see/not see.

The creation of new phenomena, requiring new laws and principles, at each level of organization of a complex, and often non-linear, system. This concept from physics has been applied to geomorphology (Harrison, Transactions of the Institute of British Geographers 26), where attempts to extrapolate from relatively brief-process measurements to the lengthy evolution of macro-scale landforms have been problematic. One explanation for these problems is that of scale: as the scale of a landform increases, so new qualitative properties emerge, which may not be predictable on the bases of analyses at smaller scales. Thus, braided channel switching may be totally underivable from the character of the micro-scale sediment transport events. The implication is that the analysis of macro-scale geomorphic systems is only possible on a macro time-scale; correspondingly, the analysis of micro-scale geomorphic systems is only possible on a micro time-scale.
