3.(10%) Brunsden(1989)曾提出10條地形學定律，如下所示。請挑選其中2條為例,就自己的所知說明需要遵守或不遵守的理由? (1) The style and location of landform change is determined by the type, location and tate of tectonic movement. (2) Landforms are shaped by tectonic and denudation processes proceeding concurrently. (3) The lower boundary for landforn development is set by varying sea levcls. (4) For any given set of environmental conditions there will be a tendency to produce a set of characteristic landforms. (5) Landforms are contirually subject to perturbations. These impulses are episodic and compliex. (6) Within each tectono-climatic regime. landforns are produced by specific process events called formative events. (7) New landforms are produced when an event is reached on the frequency-magnitude scale of a given tectono- climatic regime and a geocatastrophe occurs. (8) When a perturbation exceeds the resistance if the system will react and relax toward a new stable state or characteristic form. (9) There is wide spatial variation in landform sensitivity to change. Hence landscape stability is diverse and complex. (10) The ability of a landscape to resist impulses of change tends to increase with time.
